EGF

EGF stands for epidermal growth factor, a signaling protein involved in cell growth and repair pathways. Cosmetic ingredient lists may use recombinant peptide-style names such as sh-Oligopeptide-1, and delivery into intact skin is a key practical consideration because growth factors are relatively large and fragile molecules.

Systematic reviews describe promising aesthetic and wound-related applications of EGF-containing products, but formulations, delivery methods and study quality vary. Topical cosmetic EGF should therefore be presented as an emerging repair and age-support technology rather than a guaranteed regenerative treatment.
