Topical human platelet extract and vitamin C both help rejuvenate skin on the dorsal hands: Study

This prospective, long-term study used photographic documentation was used at baseline, 6, 12, and 26-week evaluations to evaluate typical aging-related skin issues. The primary finding of this study was found that at 12 weeks following twice-daily topical application, topical HPE was not inferior to topical vitamin C for improving the fractional areas of wrinkles, brown spots, and luminosity on the dorsal hands. Despite their different function, vitamin C and HPE were both useful skin-rejuvenation therapies.

While vitamin C serves as an antioxidant and free radical seeker, protecting cells from oxidative stress, HPE offers other benefits for skin rejuvenation, including angiogenesis, collagen formation, and inflammatory management. Both compounds in a topical serum, brighten and level out skin tone while reducing photoaging symptoms including wrinkles, erythema, and brown spots when applied consistently as part of a skin care regimen. Only 50% of the overall sample population completed the research between 12 and 26 weeks, and there were few darker skin types (8% Fitzpatrick IV or V, 0 type VI), as well as a limited number of men. Overall, after 12 to 26 weeks of twice-daily topical use, HPE is equally effective as vitamin C to rejuvenate the skin on the dorsal hands.
