R-(SH-POLYPEPTIDE-102 SH-POLYPEPTIDE-103).

This ingredient functions as a recombinant human peptide, specifically created by fusing the genes that code for sh-polypeptide-102 and sh-polypeptide-103. While detailed mechanisms for this exact fusion are not extensively documented, sh-polypeptides as a class are understood to promote the proliferation and regeneration of skin cells. They are known to aid in dermal repair and wound healing, stimulate the biosynthesis of collagen and elastin, and consequently reduce the appearance of fine lines and wrinkles while improving skin firmness and elasticity. Additionally, they can enhance moisture retention. Some sh-polypeptides also exhibit potential skin brightening effects by inhibiting melanin production and possess anti-inflammatory capabilities. It is important to note that sh-polypeptides typically do not penetrate the epidermal barrier of intact human skin under normal application, suggesting a primarily localized action.
