Working at a cellular level, bioactive collagen serum immediately improves the skin's hydration levels resulting in a visibly smoother, plumper appearance. Furthermore, it stimulates the skin's natural regenerative mechanisms; encouraging the formation of new collagen and elastin for firmer, more supple skin that glows. Powered by sH-polypeptide-121 or tradename HumaColl21, it is the world's first vegan, collagen peptide that mimics the structure and function of human collagen type 21.  HumaColl21 triggers our skin cells to produce Type 1 collagen in our skin at any age.
