| PEP-GHKP01 | Gly-His-Lys-Pro tetrapeptide, classic cosmetic active tetrapeptide that boosts collagen secretion in fibroblasts, for skin anti-aging and in vitro cosmetic efficacy evaluation research | Gly-His-Lys-Pro is a well-documented cosmetic active tetrapeptide. It targets dermal fibroblasts in skin dermis, significantly upregulates type Ⅰ/Ⅲ collagen and elastin expression to accelerate extracellular matrix synthesis. Meanwhile, it scavenges reactive oxygen species and inhibits matrix metalloproteinase (MMP) expression to reduce collagen degradation. Widely applied in research on skin aging mechanism, fibroblast in vitro culture, anti-aging skincare efficacy screening and skin barrier repair cell assays, commonly used in cosmetic raw material development and skin pharmacology studies | Skin pharmacology, cosmetic active ingredients, skin anti-aging, collagen regulation, fibroblast culture, anti-oxidation research | Dermal fibroblasts, type Ⅰ collagen gene, MMP metalloproteinase, Nrf2 anti-oxidation pathway |
