Beauty Tips For Body Care
Hey guys!This is the second post of the wiki update series!Each week a new wiki page will go live and we’ll have a discussion post like this one to go over the research, talk about the ingredient, and give feedback on the wiki page! Click here if you want to check out the post schedule :)Some general advice: don't go on a random shopping spree and buy all the vitamin C products, you might already have a good routine going that just needs more time! Do introduce products 2 weeks apart and patch test before you use it on your whole face.Keep in mind that there are no magic ingredients - vitamin C is pretty rad, but your overall routine is most important. Remember: ymmv!We focused primarily on clinical trials, so the wiki may look a bit different from other vitamin C overviews. Have no fear, though - there are additional overviews listed in the Resources section for all your in vitro and ex vivo needs. Vitamin C - click here!Vitamin C is an antioxidant that may help with various skin concerns. There are quite a few types of vitamin C with different pros and cons for each - we’ve covered some of the most common types below!EffectsAscorbic Acid (L-AA)Lightens dark spots (hyperpigmentation) 1Treats general redness 2Can help even skin tone 2Treats fine lines 3, 4L-AA is a fantastic choice for vitamin C, but it can be a rather unstable ingredient that’s prone to breaking down when exposed to heat, light, and air.5 Fortunately there are ways to improve the stability of L-AA products including:Using products with airless pump packaging and opaque containers (you can also wrap aluminum foil around your container to block sunlight)Storing your L-AA product in a cool, dark placeUsing anhydrous (water-free) formulas (although there isn't much research available on how well they penetrate the skin)Using products that also include ferulic acid 6While L-AA is likely your best bet if you're looking for a vitamin C product with effective antioxidant benefits,7, 8 it may be irritating for some due to its relatively low pH. If you have sensitive skin, you may prefer to use a different form of vitamin C.Sodium ascorbyl phosphate (SAP)SAP is a stable form of vitamin C and is an effective acne treatment.9-11 Since SAP works best at a relatively neutral pH,12 this would be a good option for sensitive skin!Magnesium ascorbyl phosphate (MAP)While there have been some in vitro studies suggesting it may be a good treatment for hyperpigmentation,13 there aren’t many solid clinical trials for MAP. That said, MAP is a stable derivative of vitamin C that works best at a pretty neutral pH (5.5 - 8),5 making it a good choice for sensitive skin.Misc. (ATIP, ascorbyl glucoside, etc.)There are many different types of vitamin C - too many to list here! Many of them don't have a lot of research backing them up, but you can learn more about the different forms of vitamin C in the overviews below :)How to useHow you use vitamin C is totally dependent on the product! There are many different types of vitamin C and many different formulations, but a general guideline for routine order looks like:L-AA Serums - Water Based - These are pH dependent products that work best at a pH <3.5.8 Since they tend to have a thin consistency and are pH dependent, you should try to use them early on in your routine, ideally right after cleansing.L-AA Anhydrous Suspensions - Water-Free - Anhydrous formulas improve stability, although there isn't much research available on how well they penetrate the skin. Since these products tend to be thick, it makes sense to use them later on in your routine - either right before or right after moisturizer.Everything Else (MAP, SAP, etc.) - These products aren't as finicky as L-AA - they tend to be quite stable and generally work best at a relatively neutral pH range. You may want to use these after any thin pH dependent actives you might be using (like AHA or BHA toners), but it mostly depends on the consistency of the product.Product RecommendationsSee our Holy Grail Vitamin C recommendations:Holy Grail Vitamin C Post 2018Ascorbic Acid (L-AA)Water Based SerumsPaula's Choice C15 Super Booster (15% L-AA)Garden of Wisdom Majik C Serum (15% L-AA)Skin Actives L-AA Serums (15% & 20% L-AA)Skinlex 20% L-Ascorbic Acid Serum (20% L-AA)Timeless 20% Vitamin C (20% L-AA)NuFountain C20 + Ferulic (20% L-AA)DIY Vitamin C Serum | NOTE: Measure ingredients by weight, balance the pH, and add preservatives. | Visit /r/DIYBeauty for more information.DIY Vitamin C SerumSkinceuticals Dupe DIY Vitamin C TutorialAnhydrous formulasStratia C+C Serum (10% L-AA + 5% ascorbyl tetraisopalmitate)Making Cosmetics 20% L-AA in Silicone (20% L-AA)Indeed Labs Vitamin C24 (22% L-AA)The Ordinary Vitamin C Suspension 23% (23% L-AA)The Inkey List 30% Vitamin C Suspension (30% L-AA)Sodium ascorbyl phosphate (SAP)Mad Hippie Vitamin C Serum (10% SAP)Ole Henriksen Truth Serum (unknown % of SAP and calcium ascorbate)DermaE Concentrated Vitamin C Serum (unknown % of SAP)Magnesium ascorbyl phosphate (MAP)Timeless Hyaluronic Acid Vitamin C with Matrixyl 3000 Serum (5% MAP)Silk Naturals Vitamin C Serums (3-5.5% MAP)The Ordinary Magnesium Ascorbyl Phosphate 10% (10% MAP)ResourcesL-AA vs the derivatives by u/stressfacedHow do I know if my vitamin c serum has gone bad? & comparison of new vs oxidized vitamin c (ascorbic acid only)Stability, transdermal penetration, and cutaneous effects of ascorbic acid and its derivatives (full text)Vitamin C chart made by /u/BlatantTomato (source post)Vitamin C Masterlist made by /u/Sophrosynia - (it's based on the chart above, but more extensive)If you want to add information to the Masterlist, go hereContributorsu/-punctum-Thank you so much for helping out with the Vitamin C Research Thread!!SourcesOur discussion questions:Did you learn anything new about vitamin C?What are your own experiences with this ingredient?How does the wiki page look?
