VITAMIN C In Your Skincare Routine: Brightening, Hyperpigmentation & Clear Skin


Hey guys, it’s Felicia, and Rowena! So welcome back to our third series of A, B and C’s of skincare. (*both singing*) A, B, C, it’s easy as 1, 2, 3! In our previous episodes, we’ve covered vitamin A, otherwise known as retinol or retinoids, vitamin B3 known as niacinamide, and today, you guessed it! We’re on that vitamin C! So vitamin C is one of those cult favorite ingredients, but has made a name for itself in the skincare world to be a little hard to work with because of its, unstable nature. Maybe like that unstable, sensitive friend that you might have. But when you probably figure out how to, use or incorporate it into your skincare routine. It can completely, brighten, lighten and protect your entire face and skin from premature signs of aging. So, today we’re going to explore what is vitamin C. How does it help with restrain collagen, increasing brightness and more? What are the different types of vitamin C and its derivatives? The best ways to incorporate it into our skincare routines. Skincare ingredients that work best with vitamin C. Debunking a popular myth. And, of course, product recommendations for your specific skin type. 🙂 So, let’s jump into what is vitamin C. So when we think of vitamin C, most often We just think of like oranges or any kind of citrus fruits. (Grapefruit my favorite!) *laughs* As well as an ingredient in our favorite serums or moisturizers But let’s explore it a little more because there are so many, different forms that they actually appear in. First of all, vitamin C in its purest form is also known as Ascorbic or L-Ascorbic acid. It’s a naturally occurring nutrient in our bodies. And we need it to function normally to repair itself and restore tissue in our bodies. Vitamin C also helps our body produce protein, and it’s recommended to help fight colds when we feel a little under the weather. Felicia: When it’s sniffles time. 🙂 Vitamin C is water soluble which means that our body, doesn’t actually produce or store it, but when we consume it, it’s completely absorbed in the small intestine during digestion. And it also helps to absorb other nutrients that we consume in the body. So you’ll find a lot of vitamin C in fermented foods, in raw fruits and veggies, like citrus fruits, spinach, yellow peppers, strawberries, brussel sprouts, black currants, kiwi, guava. Rowena: I’m hungry 😀 So, there’s a lot of things but when we apply vitamin C to our skin topically in you know, our skin care products, that’s when things start to get a little interesting! So, first of all, What is vitamin C even good for? Vitamin C is well known for its ability to brighten the skin tone, even out skin texture and smooth out fine lines and wrinkles. It’s also known as the MVP of protecting the skin against free radicals and UV ray damage, from the sun because of its high levels of antioxidants. On top of that, it’s involved in helping the skin produce collagen and, Elastin in the dermis layer of the skin, which are two of the most important factors, for maintaining bouncy, soft and youthful looking skin. But even with all the studies and raving reviews that you see everywhere about vitamin C, many dermatologists acknowledge that vitamin C helps with radiant skin, but other ones, such as Dr. Dray, argue that there’s a lack of evidence to actually determine whether the amount of Vitamin C, used to formulate the serums is able to be completely absorbed into the skin and, whether or not it actually shows promising results because of its unstable nature. How does vitamin C work in our skin? Collagen and elastin both lie in the dermis layer as proteins that give structure to our skin. While elastin keeps the skin firm, bouncy and retain its shape, collagen acts as the glue that binds the cells together. And what vitamin C does is interact with the amino acids, within the collagen cells and adds hydrogen and also oxygen to boost the collagen production. So, it’s kind of like a booster shot to the skin system to regenerate and, you know, give that healthy glow, healthy skin. So, it’s just like instead of the downward spiral of skincare, it’s an upward! Yay! So, now that we know how vitamin C works, let’s dive into the many different types of vitamin C we can use for our skin. As we said before vitamin C actually comes in pure and derivative forms, and depending on different products, you’ll see different types. So, let’s first take a look at vitamin C and it’s purest form. Felicia: *whispers* Pure! Purest! So it’s also known as Ascorbic Acid or L-Ascorbic Acid. So these two terms are kind of interchangeable and it just refers to the strongest and purest form of vitamin C. This means that it’s the only form that your body can actually recognize and utilize right away. Kind of like with vitamin A, how there’s retinoic acid and if you use retinol, it has to turn into a retinoic acid, you know, it’s like a two-step. So this is PURE.
Because it’s super concentrated and potent, it means that it works almost immediately to bring all the benefits, we mentioned of lightening, brightening, boosting collagen, fending off free radicals, etc into the skin. But the downside of Ascorbic Acid and L- Ascorbic Acid is that they’re very, unstable ingredients unlike our retinol and niacinamide buddies. What unstable means is that the ingredient itself is very sensitive, it can change very easily depending on temperature, light, air in the environment. This means it’s much more likely to oxidize, change in color and turn in consistency. Basically, go bad quickly compared to things like vitamin A, retinols and niacinamide, which is super stable. This is part of the reason why you’ll hear that vitamin C is hard to use. What are the vitamin C derivatives and how do they work? Because of its instability that we said before no one wants to deal with unstable things. Formulators and scientists behind a lot of different skincare brands have developed more stable forms of vitamin C known as derivatives. So this just means that because it isn’t the pure form, it won’t go bad as easily when formulated with other ingredients in the product. But it also won’t cause things like inflammation when used in your skincare routine because we have so many different products. And this inflammation can be a result of using the pure ascorbic form of vitamin C. When derivatives are absorbed into the skin the body breaks down the derivative into ascorbic acid Which can then act to function just like the actual antioxidant. And with that being said, it’s once again less irritating to those of you with sensitive skin, or for those of you who haven’t used any sort of vitamin C. Derivatives can also come in oil and water-soluble forms. Now that we know this, there are actually a lot of different vitamin C Derivatives used in popular skincare products. Let’s look at three common examples and where we can find them. So one of the many forms of vitamin C Derivatives includes the Tetrahexyldecyl ascorbate, otherwise known as THD, just for sanity’s sake. And this is known to be the gold standard form of vitamin c derivative, because THD is known for its skin brightening and hyperpigmentation lightening properties. It also has fatty acid components that make it oil-soluble and it helps to penetrate deeper into the layers of the skin It’s also oxygen stable which means when the ingredients in the product are exposed to air, it won’t go bad THD is found in many oil serums as well as moisturizers and often gives the product a creamy texture with Moisturizing properties for the skin. So it works really well with people who have dry skin or for spot treatments to target hyperpigmentation or melasma, But also with most other skin types. So you can find this derivative in products like the Biossance Squalane and Vitamin C Rose Oil. This contains THD as well as sugar cane squalane to hydrate the skin, rose extract that also helps to soothe and even out skin tone. There’s also the Supergoop Antioxidant- Infused Sunscreen Mist with Vitamin C Broad-Spectrum SPF 50 This is a mist that contains a bunch of citrus extracts and oils as well as the THD derivative. And one that we’ve both tried is the Sunday Riley CEO Cream with 5% THD ascorbate. This moisturizer is powerful at fighting the first visible signs of aging and restoring vital skin radiance. Felicia: It’s definitely rich and a little bit greasy but not really greasy. (Rowena: It’s not like overwhelmingly so where you can’t handle for oily skin.) Yeah, so it like helps with hydration and gives you the antioxidant protection to the skin. Another derivative is Magnesium ascorbyl phosphate or MAP. This is a water-soluble and stable form of ascorbic acid. MAP is known to increase hydration levels as well as brighten and sooth an even skin tone. The texture for this ingredient resembles a cream and it’s good for moisturizers, although it does come in serum form as well because vitamin C is actually very popular in serum form. And some examples of this derivative comes in The Ordinary Magnesium Ascorbyl Phosphate Solution 10% but also contains Omega-6 and 3 fatty acids as well as vitamin A and E. It’s also high in linoleic acid so it should work really well for those with oily or clogged pores. And after researching this I’m definitely gonna try this one because your girl has clogged pores and has oily skin. There’s also the Osea Vitamin C serum. Although it is further down the list in the ingredients because I guess it’s a hyaluronic serum mainly aimed for hydration and moisture, and in terms of brightening it also contains a small amount of turmeric extract. And another derivative you’ll most often seen a lot of products is a Ascorbyl Glucoside. This is also a water-soluble derivative, and it’s recommended to pair Ascorbyl Glucoside with vitamin B or niacinamide for the best results. And examples where you’ll see this derivative is The Ordinary again because they just seem to have every ingredient, and derivative under the sun. The Ordinary has an Ascorbyl Glucoside Solution 12%, Skin Inc. Supplement Bar Vitamin C Serum, First Aid Beauty Hello Fab, Ginger and Turmeric Vitamin C Jelly Mask, which is something that I just put on two days ago. Rowena: And how was it? Felicia: It was good! It’s a very pleasing mask and the texture is very light very much like jelly and it is slightly brightening because it also has turmeric. Now those are just three examples of vitamin C derivatives where many products fall under but there are actually quite a lot more. Like the one we see in Tatcha’s most recent Violet – C, The one in that beautiful purple-orange sunset dusk packaging. So that one is a brightening serum which contains 20% Bis-Glyceryl Ascorbate, which is another vitamin C derivative and this acts like vitamin C to brighten and protect with high levels of antioxidants, but Tatcha also includes 10% AHA from fruit extracts to gently exfoliate and reveal new skin so that it’s also naturally brighter. And the OleHenriksen contains ascorbic acid as well as another vitamin C derivative called 3 – O ethyl ascorbic acid which helps brighten the skin through reducing melanin production. And this derivative also works to stabilize that ascorbic acid which we know is rather unstable. Yeah, so that one melanin just is in control with producing hyperpigmentation, dark spots, you know sunspots and things like that. So how to use vitamin C in your skincare routine? Good news is vitamin C is not as intimidating to use as vitamin A aka retinols, Because the majority of us can experience its benefit, so it’s not like you have to be of a certain age or specific skin type to use. Because we all want to look bright and sparkly, right? like Edward Cullen? So if you are a newbie to using vitamin C products in general, you’re going to want to start off, kind of like with a chemical exfoliant, right? You want to start with the lowest percentage or concentration of products with ascorbic or l-ascorbic acid to avoid irritation. If you’re still a little hesitant because you don’t know if your skin will like it, start off trying a product that contains one of the derivatives we mentioned before as it’s much less irritating and suitable for sensitive skin. And vitamin C boosters, like we mentioned, are also a great option because then you can just concoct and mix to your own desire. Then once you know what your skin reacts well with and you see subtle changes, then you can start working your way up the percentage level, and perhaps consider going for a product that contains 10 to 15 or even 20% of ascorbic acid, but keep in mind these levels are pretty potent. So now, are you wondering, “Does it work better during the day or the night?” The answer is both!! But we would recommend using it during the day with a sunscreen because of the Antioxidant properties and the ability to fight off free radicals, and prevent sun damage from UV rays during the day. So it’s essentially an armour on your skin during the day. But if you do prefer it at night, or there’s vitamin C products that are designed to use at night, this is also fine, because the skin and the body during the night time is in recovery and repair mode. So if you have a serum with a high concentration of L-ascorbic acid given that it’s tolerable to your skin, of course. This is a great opportunity to help the skin replenish and rejuvenate itself while you catch some sleep. (*sleep gesture*) While the day allows the vitamin C serum to act as a shield, the night allows the serum to reverse the damage of your skin from the day’s work. This brings us on to what other ingredients does it work well with. Like with other ingredients, vitamin C actually works well with niacinamide, Vitamin E, Ferulic acid which is a plant-based antioxidant. And Ferulic acid is actually highly recommended for bringing out all of the goodness of vitamin C like delivering more antioxidants to the skin and speeding up vitamin C’s effects on the skin. And vitamin E works really well with vitamin C, which is why you will see them paired together very often in products. (Felicia: They’re best friends!
Rowena: Yay!) And if you choose to incorporate niacinamide, it shouldn’t be a major problem, unless of course you are using pure vitamin c serum with a really high concentration of like 20%. Then your skin will most likely become irritated, because it is also so high in terms of pure vitamin C but keep in mind that everyone’s skin tolerates up to you know a differing degree of percentage. So definitely do your research, do your patch test, and stop as soon as you see any sort of irritation. Felicia: Now… products! What you love!
What we like to buy!! Rowena: Yay! Felicia: I have only used a few because back in the day actually reacted negatively towards vitamin C and it was only recently that I started like slowly incorporating it again. Because I have very tanned skin, so it’s not like going to brighten.
Rowena: Or like remove freckles for me. Felicia: Yeah, I won’t remove freckles…
Rowena: You don’t have them to begin with. Felicia: Yeah, well, I kind of do but you don’t see [them like you do on you]. So one that I want to mention is the Paula’s Choice vitamin C15 Booster So this one has 15% L-ascorbic acid as well as vitamin E, Ferulic acid and peptides What I love about these boosters because they have a whole range… I like that you can kind of customize it into what you want to boost. So you can like add it into your serum make it like a hyaluronic vitamin C’s concoction. Rowerna: Niacinamide…
Felicia: Yeah! Or you can add it into your moisturizer. So like depending on which step of the routine you feel comfortable with, you can you know decide on that yourself. But then you can also decide on the amount. It can be like one drop, which is tiny a little bit, or Three drops if you feel comfortable.
Rowena: (*mimics squeezing dropper*) Or like the whole tube… Felicia: Yeah… I’ve never tried that. That would be a little bit scary Another product that we’ve both tried. (to Rowena) Probably you can talk about this, is the Drunk Elephant C-Firma Vitamin C Day Serum Rowena: It’s great for a dry mature skin and has 15% l-ascorbic acid, 1.5% Ferulic acid, 1% vitamin E. I think like when I used it consistently every single morning like a year ago, it worked beautifully. Felicia: Really?
Rowena: Yeah, and then I stopped for a few months and I went back to it to finish because I was like Oh, Is vitamin C, it’ll go bad, I need to finish it. That also worked really well. But then when I went back to it, maybe a few months ago, it didn’t really do much, so I stopped using it. When you first used it, was it already that orangey color? I don’t know if it was formulated that way… I think in the very beginning it’s like a light oil. It’s kind of like a light oil texture. And then as you use it, you can start seeing little specks of more oranjey things in there. Felicia: Okay.
Rowena: And then at the end which will show you guys in the b-roll, if it goes bad, it’s just straight like Dark brown orange.
Felicia: Yeah, and actually just to mention the ingredients of this one. You always see vitamin C, and E, and ferulic acid. And we’re gonna explain why these ingredients actually work really well with Vitamin C If you guys are into CosRX, they also have a Triple C Lightning Liquid, which is good once again for dull skin and also hyperpigmentation, and any skin types who can tolerate a 20% of ascorbic acid.
Rowena: I feel like I want to try. Felicia: Yeah! And the good thing about CosRX is that they’re super affordable. As well as the pure ascorbic acid, it has 72% of black chokeberry and this ingredient helps to stabilize the high concentration of pure ascorbic acid. That bottle is black, and vitamin C because it’s so unstable, which means air heat, light, anything will affect its stability, right? So the fact that it’s in this black bottle is definitely to help the longevity of it. So another one that we have is the Klairs Freshly Juiced Vitamin C Serum. And this one is completely it’s clear and watery and it’s great for sensitive and combination skin types. It’s also a really good vitamin C product for those of you who are starting out because it does have a lower percentage of L-ascorbic acid As well as really calming ingredients like centella asiatica extract, which is one of those like just soothing calming, reducing redness, as well as usual fruit extract. Felicia: This one, I’ve also tried but also not long enough that like see results. I think with vitamin C. I’m very not dedicated to keeping it going.
Rowena: I think it’s just a reflection also of our generations’ impatience, and how we want immediate results. But another really popular and more like high level of ascorbic acid product is the Timeless 20% vitamin C and E, ferulic acid serum that you can get on Amazon. Super inexpensive and it’s great for mature skin as well as just any skin that tolerates 20% This product is also much lower on the pH level because vitamin C products normally range around the 3 pH level, This one is 2.4, which means that 1: It’s very unstable, it’ll probably only last you up to three months before it starts to like decompose in the way that vitamin C does. But it can also be quite irritating, because of the low pH level, because it’s so acidic, and because of the high levels of ascorbic acid. So just keep that in mind, if you are like a vitamin C lover guru, then this is also a good one. As well as that, Ordinary Vitamin C Suspension 23% with the HA Spheres 2%. So this has 23% ascorbic acid powder. It’s also got sodium hyaluronate. And the consistency is like a kind of heavy serum formula, because of the fact that they add powder vitamin C. But it also absorbs quite quickly. So that’s also an inexpensive option. When will I see results after using Vitamin C in my routine? So results definitely vary from person to person. Vitamin C generally takes around two weeks or a month of daily use to see brightening benefits and about three months to see the benefits including tone improvement and collagen production. Felicia: I would prefer using niacinamide. Because it is so much more stable, easier to use, it almost gives the same benefits, you know. It produces collagen, it helps even skin tone. It also helps minimize pores because it helps to control oil. So all those things actually help me much better than vitamin C, and so like vitamin C is kind of just an add-on. So with like the ABCs you kind of just like pick and choose which one according to your own kind of needs We always hear vitamin C is not compatible with niacinamide. So what’s the truth and the myth about this vitamin C pairing? The myth is vitamin C and niacinamide are a dangerous combination to use for our skin because the effects of both are going to cancel each other out, and also create nicotinic acid aka Niacin, which can cause redness and tingling to the skin. Actually the combination of vitamin C and niacinamide is perfectly safe. It’s like a sinergy, because they both boost each other’s ability to brighten and protect the skin, and also fend off from free radicals and harmful UV rays. These claims are actually made back in the day and we’re talking like nineteen sixties of when skincare researchers and product developers were working with very Unstable forms of vitamin C and the pure forms in an isolated and a controlled environment so basically the form of ascorbic acid they were dealing with was nowhere near close to what we have today in the products that we see today which are actually designed and formulated to be used in conjunction with other ingredients. Of course, just test it out on your own skin. See if there’s any tingling, redness and if it is a high level of pure ascorbic acid, then maybe skip out niacinamide. Very easy. Just use one at day one at night. So that was our comprehensive round up of vitamin C. This concludes our ABC’s of vitamins, which is actually pretty exciting because these are the most probably well researched ingredients, would you call it? Or nutrients? That we can ingest but also apply topically, and they kind of work in different ways. Felicia: Let us know if vitamin C works for you guys…
Rowena: And how you use it. And when do you see the most benefits? Felicia: Yeah, and like what age range you felt like it was most useful. Because we’re also curious. Ya know? But don’t go anywhere because we also have the most hyped products playlist, helping you guys figure out which ones are actually worth it. Our basic skincare… If you have any questions, we’ve probably made a video about it. So make sure you check that out! It will be here on the screen soon. Rowena: And there’s a lot more to come so stay tuned and don’t go anywhere. Felicia: (*sings) Don’t go anywhereeee… Rowena: You can just go home and wash your face. Felicia: They’re probably at home anyway~ Rowena: And, we’ll see you next week. Bye!!!

    Is Vitamin C safe to use with Azelaic Acid? My skin can handle the strong products, I'm more concerned about the products not cancelling each other out or reducing the effects?

  • Rifa sain

    Lovely video, I also want to know about the ingredient glutathione on skin serums and creams. Is it good? Thank you <3

  • Nanor Balian

    What do you think about the 'The Ordinary Ethylated Ascorbic Acid 15% Solution 30m' for acne prone skin?

  • skincareaddicted

    When I used it and not sure if it has changed, Drunk elephant added ingredients that color their vitamin c. IMO, it’s deceptive because the color change isn’t as obvious at first. It turned really quickly on me and when I contacted their customer service, they kept telling me it was fine to use. Shortly after, they officially changed their shelf life recommendation. I should have returned it to Sephora but did not save the packaging. After this experience, I will never purchase drunk elephant again. I just don’t think they are ethical despite their branding.

  • darkdistiller

    Thank you for pointing out it's instability. Vitamin C is over blown, and while you will see some benefits, they are often short lived thus you have to keep buying endlessly or your skin will go back to how it was prior. You see this 100% of times with people who buy it for dark spots and wrinkles. People think the dark spots and wrinkles are gone., they move on to another product, and the same spots and wrinkles come back soon after. It's a temporary fix that can end up costing you more money than it's worth. Even the more stable derivative will have temporary benefits. As you said the instability of vitamin C means you may end up with a product with a much shorter shelf-life and benefit than you though and it's really hard to say when the vitamin C will turn and is no longer going to be giving you any benefit. This can be from as soon as a few days of opening your product to a few weeks. If the product lets say changes color, loses or changes odor that likely means the vitamin C has now expired and thus has lost it's potency. Which means if you spent $50 on a cream or serum that boasts vitamin C as it's main active ingredient and it turned within that first week, you now have a very expensive bottle of mostly wasted product. I find that tea extracts and some plant extracts can get the job done and are a lot more stable. Load up on products that contain a lot of antioxidants to protect your skin and always use sunscreen to avoid further damage! However I do want to add that there is no cream, or serum on gods green earth that will ever totally get rid of all your dark spots and wrinkles permanently. The more damaged an area is the deeper into the tissue that damage has occurred at. Topical products can not absorb deep enough into the tissue and reach the damaged layer where some of these issues stem from. So essentially you will see some of these spots and wrinkles come back up and surface over time. If you have the money to get professional (at a dermatologist office, not a spa and definitely not at home if it is over 0.25ml) micro-needling done to treat dark spots, wrinkles and see far longer lasting benefits it's worth the money. It's the closest thing to permanently reducing those problems.

  • Annmarie Normile

  • Louise Querubin

    I got sooo into the channel after I watched the vitamin b niacin-amide episode. So thankful with your channel as I am learning on how to better take care of my skin. I didn’t really do much to my skincare at the beginning when I was a teenager. but I have experimented way too much since then that it made my face so sensitive that I would get really dry and patchy skin every season changes (I live in Canada) this happened when I was 20-23 and since I turned 24 I have been very careful with my skincare. Although I was still confused on how to take care of my skin especially now that i am turning 25. I have to learn more on how to take care of my skin. And with your videos I have learned so much and will make some changes in my skincare routine. I just want to ask how to incorporate retinol, niacinimide and vitamin c in the korean skincare routine as it is what I am doing. I would like to know Step by step so I don’t make the same mistake as I did, putting the wrong ingredients to my face.

  • Alexandra Charlton

    Probably not going to answer but is too many vitamins in skincare bad for you? I have a cleanser with vitamin e in it and a serum with vitamin c and b. Even my moisturiser had vitamin e in it. I'd really like to know thank you.

  • Paige Huzyak

    I was a little disappointed that y'all presented the argument that some doctors don't believe that vitamin C works when applied topically, but didn't offer any evidence to the contrary. You made the point that there wasn't great evidence, then went on talking about vitamin C and it's derivatives like they were a sure thing. It was better than not mentioning the doubts surrounding vitamin C's efficacy at all, but if you treat the topic so confidently, I would like to hear why you believe these ingredients give real results.

    It sounds like it may be best to avoid vitamin C because it's pretty irritating, but the benefits aren't well-supported, let alone proven. There is some evidence that they may be harmful. I'm doubtful of an ingredient that oxidizes so easily being a powerful antioxidant on the skin. It may interact with oxygen to produce harmful by-products. https://www.oumere.com/blogs/news/the-3-reasons-why-vitamin-c-serums-are-bad-for-your-skin

    I could be wrong! I just haven't found any good evidence from reliable sources about topical vit C's efficacy. I'd like to hear some.

  • Nicole Jade Gonzaga

    I love your videos. You two bounce off each other really well. As a newcomer into the skin care world/realm, your videos have helped inform me about certain products! I love the animations and the aesthetic of the videos. You both are goals! Would love some advice on what you guys think of brands like ultravioletteau, natio skin care, josie maran, TATA harper, estee lauder advanced night cream, KIELHS, Jurlique, Then I met you, Neogen, Biologique Recherche Lotion P50, Youth to the People, Sunday Riley and MURAD!!!

  • Cashmere4500

    Just discovered your channel! Brilliant!! Filling a gap in skin care education online. Great ‘scaffolding’ of clear information. I’m 40+ years old and never too old for ‘beauty school’! Love it.

  • Assia Haa

    I do use vitamine C in several steps of my skinroutine. My cleanser, serum, nightcream and mask all contain vitamin C (brand: image skincare) and I have defiintely experienced the benefits! My skin is brighter and it has reduced some darker spots on my face…

  • Bhanavi Mathur

    I want to start using the Klair’s freshly juiced vitamin c serum. But I’m currently using The Bodyshop’s Tea tree daily solution because I had a very random spurt of acne for the first time in years. Can these work together? Or should just use the vitamin c? Help! @beautywithin

  • Sam Salt

    Hey girls, you have been my bible when it comes to skincare. I need your help coz I can't seem to find the answers on my own. I am currently using Pyunkang Yul Acne Cleanser in the morning, Cosrx Salicylic Acid Daily Gentle Cleanser in the evening, Pyunkang Yul Mist Toner and because I used to get a few acne cystic acne and I got some dark scars, I use Tiam's My Signature Red Vitamin C Serum on some parts of my face and on some I use Niacinamide from a local brand called Apotheke Science with the following ingredients (Niacinamide 10%
    Niacin in a bed of aloe vera extract, aloe vera gel, and
    Sea weed extract).

    I apply both serums in the morning and the evening as I stay at home all day.

    So far I haven't had any pimple for a few weeks now and the marks are slowly disappearing but when I saw this video and the one on what chemicals shouldn't be mixed together, I realised that maybe my vitamin C is not that potent because my cleanser contains salycilic acid, my toner has butylene glycol and sodium hyaluronate and other ingredients that were not supposed to be mixed.

    Am I sabotaging my skin care routine by pairing ingredients that don't go well together? Im worried what this might do to my skin in the long run.

    Can you recommend a cleanser and toner that would go well with my Vitamin C serum?

    So i used the ordinary salicylic acid serum in morning and euk 134 and retinoid on alternative days. How should i incorporate vitamin c into my routine pls?

  • Tenshi's Kiss

    I started using Vitamin C a month ago (I’m 26 this year) and I can see a difference in my skin texture and it looked lightened. Mom touched my face yesterday and she said it was as smooth as my baby brother’s butt….now that I think about it, I hope she washed her hands before she touched my face…😓😓😓😓

    i am really a total new be….in everything that a normal girl does……and i mean the beauty routine and make up stuff……i have never worn make up in my life, except in college when i was forced by my classmates to ware an eye liner and it was really a good thing that i studied in an all girls college in India…… and i admit that i am a total tomboy and in school i studied in a co-educational school and so i had two groups as in one group was all boys and the other was all girls……..but i mainly felt comfortable on my own, and on occasion, i would go to my best friend ,who was my classmate since 5th grade, to just have some all girls time, but the leader of the all boys group, and also my FAMILY FRIEND and CLASSMATE from 7th grade till 9th grade, would always wait for me and my friends would laugh and say "Becky…..i think someone is waiting for you" and they would point and when i looked in that direction, i always so him and his group at the door waiting for me and it always got me into trouble because both my groups would tease me by calling him my guy and it used to get me so mad that i even caught another guy by the collar and threatened to break his nose if he dared to tease me or my family friend again, once and he caught me in that pose and after that he always kept an eye on me………so back to my college days, the only thing i used to ware was just a lip balm and that was it……and then one day, one of my ex schoolmates and college classmate asked me "Rebecca, why don't you wear any makeup?" and i just told her "that's because i don't like makeup….and also my mum would kill me if she saw me with makeup" and my best friend and college classmate who was also my batchmate and classmate in school told me "Rebecca, we know that you were a total tomboy in school….but now we are in college and i think that it is time that you STOP ACTING LIKE A TOMBOY AND ACT LIKE THE GIRL you are" and so i ended up wearing eyeliner just to make my ex school mates happy and when i looked at my best friend with the eye liner on, she just was like "WOW! YOU LOOK BEAUTIFUL" and i immediately took the eyeliner off and when the other girls in my class heard her say that they were like "Really?Rebecca, look at me?" and i looked at them and told them "i am really sorry, but i just took it off" and they forced me to apply the damn eyeliner again in front of them and then when i looked back at them, the girl who asked me why i didn't wear eyeliner, just went speechless and she was like "God! Ankhi was right! no wonder why you don't wear makeup! and why your mum doesn't like you wearing makeup!" and the other girls in our college group looked at me and one of them actually told me "if i was a guy I HONESTLY WOULD HAVE SERIOUSLY FALLEN FOR YOU! YOU REALLY LOOK GORGEOUS!" and the other girl was like "i really think that you should take that eyeliner off before you leave college or you might get into deep trouble with the guys outside our college gates" and that was the end of things…….and i of course told my mum this and she was angry but she said that it was good that i took it off before she saw it because she would have kicked my bottom…..and also i have had too much of unwanted attention from the guys out side my college gates and inside school that just before my family friend joined my school, my school had to use metal sheets to block the grills in the gate because i had been groped on my chest by some guy during my sports day in my 6th grade and everyone knew about it because it happened in front of everyone and not only that when ever i tried to run away from that guy, he would always follow me and finally i was cornered, but i saw a teacher just in time and i ran to her and told her everything……so yeah, i can't wear makeup because either way, i get groped and other such dirty stuff…… but i still would like to have a good beauty routine just to maintain my skin…… 🙂

    Can you please suggest which vitamins C are better for acne-prone skin. I read Drunk Elephant vitamin C caused a lot of break-outs/acnes to people who have acne prone skin

  • Camille A.

    Great video but now i'm confused. i'm using some products from the ordinary and they have this contraindication for niacinamide:
    "Contraindications: If topical Vitamin C (L-Ascorbic Acid and/or Ethylated L-Ascorbic Acid) is used as part of skincare, it should be applied at alternate times with this formula (ideally Vitamin C in the PM and this formula in the AM). Otherwise, Niacinamide can affect integrity of the Vitamin C" What are your specific thoughts on this since you mentioned not pairing these products was a skincare myth?

  • _different _girrl

    What about serums that combine vitamin c 20% ,niacinamide 3.5% , retinol 2.5% and salicylic acid 2% are they safe and effective?

  • Steffi Reyes

    Can I use the Drunk Elefant Vitamin C Serum with the Paula's Choice Niacinimide Booster???? Or should I just switch out to a Niacinimide Serum? I have acne scarring I would like to get rid of.!!

  • Marla Luna

    Can someone please help me! So I bought the Vitamin C Serum from Klaris a while back, and when I first got it it was clear. Now it has turned into a light yellow color. Has anyone else experienced this, if so is this normal or do I have a faulty one? Thanks!

    Hello can you do a video comparing the rosehip seed oil and niacinamide?I've heard you rave about niacinamide. But would like to know how it compares to rosehip seed oil

  • Cindy Amarasangghadewi

    What if the combination between L-ascorbic acid powder from The Ordinary mixed with niacinamide, is it safe?

  • ikkial

    I wanted to lighten my dark skin since I tan so easily on the face.
    Usually I use Niacinamide as a main ingredient it did good with lightening but just quite slow to be effective.
    So I wanted to try & experiment with something new.
    I tried Vitamin C solely because of the rave from people,
    but dang I'm so regretting my decision.

    Well it did even out the skin tone,plump up the texture,refine pores & fine lines but nothing close to lightening.

    If you naturally have a tan skin it will emphasize that bronze tone of the skin as it's main function is to brighten.

    I wanted to use Vitamin C in the morning instead of night since it fights against the harsh free radicals & all.
    But geez the tacky feeling was so unsettling.

    Starting now just like Felisha had said,Vitamin C is going to be just an addition instead of a main ingredient for me.

    Can't wait for my next payday to restock my Niacinamide babies.

    Since Vitamin C works well with Vitamin E. And can work well with Niacinamide. Can Vitamin E and Niacinamide be used together on thier own?
    I feel like I just gave you a math problem lol. Sorry.

  • Emerson San Pedro

    Niacinamide for the win for me. So cheap so easy to use. I'm on my second bottle now of the ordinary. My pores are smaller. Less oilier skin.
