    Glossary Tripeptide-1

    small protein fragment promoting collagen and hair growth

    Tripeptide-1, also known as GHK (Glycyl-L-Histidyl-L-Lysine), is a small protein fragment composed of three amino acids. It is known for its role in skin and hair care due to its ability to promote collagen production, wound healing, and hair growth. This peptide is often included in anti-aging and regenerative products because it can help improve skin elasticity and reduce signs of aging.
