6 peptides researched for skin & beauty.
Skin and beauty peptides target the biological processes behind aging skin. declining collagen production, reduced cellular turnover, oxidative damage, and loss of skin elasticity. These peptides range from copper complexes that promote tissue remodeling to compounds that stimulate growth hormone release, which in turn supports skin thickness and hydration.
GHK-Cu (copper peptide) acts directly on skin cells, promoting collagen synthesis and wound healing. it's available in both injectable and topical forms, making it the most accessible option. Epithalon works at a deeper level, potentially activating telomerase to extend cellular lifespan, but evidence is primarily from animal studies. Growth hormone secretagogues like CJC-1295 and sermorelin support skin health indirectly through elevated GH and IGF-1 levels. Melanotan II stimulates melanin production for tanning but carries notable safety concerns.
