Vitamin C in Skincare A Biochemist Perspective

[@KennaWhitnell]

The two ingredients I mention in the video are trans-resveratrol (antioxidant) and arbutin (Skin brightener)! Sorry for not having titles I will get better at this YT thing I promise 🤗

[@sellatagala640]

Hi kenna! That is very informative. Thank you so much. I have a request, though. Can you make a video about exfoliators? What ingredients to look for? Thank you!!!! More power to you and your channel

Thank you so much for adding the names of the two ingredients. I was trying to sound out phonetically what you said, but I would have failed.

Would you consider doing a deep dive on the ingredient dimethicone? I always see it so high on the list of ingredients in a lot of drugstore skincare. Is it bad? Comedogenic? Id love to know your thoughts! Thanks 🖤

[@Omg-Em]

Yes!!

[@davidmota8835]

Yeah, I love many products that have dimethicone and I’ve heard that is not so great and also noticed that is widely used in hair serums and antiácid like melox or riopan

My korean grandmother has been using vitamin c her whole life and her skin is literally always been flawless and now she’s 60 and barely had wrinkles and discoloration ! I recommend vitamin c ✌🏼😌

[@leecruz6781]

At last, somebody actually said it straightforward about vitamin C. 😊

[@daniak6699]

I saw a similar clip from Dr Dray about vit c, she basically said the same thing and I appreciate their honesty. She is a bit controversial apparently due to her weight(not a fan of that either), but I can tell you that her skincare advice is spot on. The problem from my perspective with the doc is that her videos are long.

[@brattynicky8672]

So should we not use vitamin c 🤣 I’m confused

[@Losshe]

@@daniak6699 As someone who is naturally thin and healthy and won't gain much weight unless I eat junk food and tons of sugar every single day, I find the controversial around Dr Dray's weight very unfair and hurtful. Everyone is built different. I do find her thinner than what I consider thin, but that's her business and her body, as long as she's not out there promoting that her body size is the ideal size, I'm fine with it

[@Popicat527]

@@daniak6699 we don't know what she's dealing with in her private life. Her weight shouldn't make her controversial as long as she doesn't claim that everyone should be like her (which she doesn't). If she has an eating disorder it's not a reason to say that she is controversial and to stop following her. She doesn't promote an unhealthy lifestyle and that's the only thing we should care about

I have been struggling lately with the fact that my skin has never liked vitamin-c products. They all had l-asorbic acid as the vitamin c component. It always irritates my skin, but as a beauty professional I always felt like that step was missing in my routine. Also, because everyone I have encountered in the skin care realm preaches Vitamin C for anti aging and brightening. I am so glad to learn there are other better antioxidants on the market!

The thing I always wonder is wether it may actually be a bad thing to lower the amount of melanin in our skin. It seems that almost all commonly used actives, retinoic acid, ascorbic acid, niacinamide, licorice extract, sunscreen etc, they all in different ways reduce the amount of melanin. And I wonder wether that's a good thing, because melanin is also beneficial for skin, it may only provide an SPF3, but still it doesn't degrade or rub off like sunscreen, it protects the skin cells, has an antioxidant benefit. Very pale skin is more sensitive to uv radiation. Wouldn't it be more beneficial to find ingredients that actually stimulate melanin production?
