The sodium salt form of skincare superstar, vitamin C. If you do not know what the big mother about vitamin C is, you are missing out and you have to click here and read all the geeky details about it. Pure vitamin C ( aka ascorbic acerb, AA ) is capital and all, but its miss of stability is a big challenge for the cosmetics industry. One solution is to create stable derivatives that can be absorbed into the bark, convert there to AA and do all the magic trick AA is proven to do ( which is being an antioxidant, a collagen booster, and a skin brightener ). SAP ( the vit C derivative, not the enterprise software, obvs ) is a promise derivative that has great stability up to pH 7. The challenge with it though is skin penetration. unfortunately, it seems to be limited, or to quote a great article from the Journal of Cosmetic Dermatology “ locally applied ascorbyl phosphate salts are, at identical best, ill absorbed in comparison with AA ”. Regarding conversion to AA, there seems to be no datum about it, so we can neither deny nor confirm it.

We have better news regarding the three magic abilities of vitamin C : there is in-vivo ( tested on real people ) data showing that SAP does have photo-protective (aka antioxidant) properties, though less than pure AA. SAP might besides aid collagen boosting; in-vitro ( made in the lab ) data shows that it works, but is less effective than another vitamin C derived function, called MAP ( that seems to be a effective as saturated AA ). As for skin-brightening, there is a trade publication with in-vivo data showing that SAP can fade brown spots.

Another thing blackjack might be able to do is to help with acne. A 2005 study showed in vitro ( in quiz tube ) that 1 % SAP has a strong antimicrobial activity on evil acne causing P. acnes and it besides showed in vivo ( on real people ) that 5 % SAP can powerfully improve the inflammatory and non-inflammatory lesions of acne vulgaris. In fact, the results were comparable or even slenderly better than with 5 % benzoyl peroxide.

And there is even more regard SAP and acne. A dainty double-blind study from 2009 showed that 5 % SAP reduced the inflammatory lesions by 20.14 % and 48.82 % within 4 and 8 weeks respectively and when combined with 0.2 % retinol the results were even better. With this combination treatment, the improvement was 29.28 % after 4 weeks and 63.10 % after 8 weeks of lotion .
apart from inquiry studies, anecdotal evidence besides supports SAP being a promise vitamin C derived function. One of the best-selling ( vitamin C ) serums in Sephora is the Ole Henriksen Truth Serum, while on Amazon it ‘s the OzNaturals Vitamin C 20 Serum. Another democratic choice is the Mad Hippie Vitamin C serum, and all of these check vitamin C in the imprint of SAP .
overall, we think SAP is a goody!   In terms of anti-aging, it ‘s credibly not american samoa effective as pure Ascorbic Acid, but it ‘s wholly deserving a test. however, if your peel is acne-prone, SAP is your form of Vitamin C and it ‘s a must-try .
