Peptides studied for skin aging, pigmentation, and hair follicle biology.
Cosmetic and dermatologic peptides are studied for effects on collagen synthesis, melanocyte and pigmentation pathways, photoprotection, and the hair-follicle cycle. The class spans copper-binding remodeling peptides, melanocortin agonists, and signal peptides that influence dermal matrix turnover.
Research endpoints include measures of skin elasticity and wrinkle depth, follicular density and anagen duration, and UV-response markers. Many of these peptides overlap with tissue-repair biology, reflecting shared pathways in matrix remodeling and angiogenesis.
Synthetic fragment of thymosin β4 studied for cell migration and tissue repair.
View profileEndogenous copper-binding tripeptide widely studied in skin and hair biology.
View profileCopper-binding tripeptide (Ala-His-Lys) studied for hair-follicle stimulation and dermal repair.
View profilePalmitoylated matrikine peptide that signals fibroblasts to synthesize collagen — contains no copper.
View profileSynthetic cyclic analog of α-MSH; non-selective melanocortin receptor agonist.
View profileMC1R-selective α-MSH analog; FDA-approved (Scenesse) for photoprotection in erythropoietic protoporphyria.
View profileThey’re studied for collagen synthesis, pigmentation pathways, photoprotection, and the hair-follicle cycle, spanning copper-binding, melanocortin, and signal peptides.
Endpoints include skin elasticity and wrinkle depth, follicular density and anagen (growth-phase) duration, and UV-response markers.
Skin and hair peptides share matrix-remodeling and angiogenesis pathways with tissue-repair biology, so the two areas frequently intersect.
