![]() ![]() 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". #Sente bio complete serum amazon skinThe 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. However, if you are the adventurous type or if your skin is sensitive and cannot tolerate retinoids, Myristoyl Nonapeptide-3 is a promising alternative. Unfortunately, there are currently no in-vivo test results (at least with could not find any), so if you prefer the tried and true, stick with retinol. ![]() They also found that both retinoic acid 0.1% and Retinopeptide 189 5% cream increased epidermal cellular layers in the skin explants showing that both ingredients can increase cell turnover, however retinoic acid did significantly better both in active effects as well as side effects. To further prove their point, Symrise (the manufacturer) went ahead and did some ex-vivo testing (meaning testing on human skin explants). They compared a 0.1% retinoic acid solution with 5% and 10% Retinopeptide 189 cream and found that the 10% cream induces a significant increase (43%) in collagen-1 that is comparable to the effect of 0.1% retinoic acid (which performed even better with more than a 50% increase).
