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.
