A nice 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. In fact, the results were comparable or even slightly better than with 5% benzoyl peroxide.Īnd there is even more regarding SAP and acne. acnes and it also showed in vivo (on real people) that 5% SAP can strongly improve the inflammatory and non-inflammatory lesions of acne vulgaris. A 2005 study showed in vitro (in test tubes) that 1% SAP has a strong antimicrobial activity on evil acne causing P. As for skin-brightening, there is a trade publication with in-vivo data showing that SAP can fade brown spots.Īnother thing SAP might be able to do is to help with acne. SAP might also aid collagen boosting in-vitro (made in the lab) data shows that it works, but is less effective than another vitamin C derivative, called MAP (that seems to be as effective as pure AA). 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.
Regarding conversion to AA, there seems to be no data about it, so we can neither deny nor confirm it.
Unfortunately, it seems to be limited, or to quote a great article from the Journal of Cosmetic Dermatology "topically applied ascorbyl phosphate salts are, at very best, poorly absorbed in comparison with AA".

The challenge with it though is skin penetration. SAP (the vit C derivative, not the enterprise software, obvs) is a promising derivative that has great stability up to pH 7. PEG-240/Hdi Copolymer Bis-Decyltetradeceth-20 Ether
