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 .
