Palmitoyl hexapeptide is a synthetic bioactive peptide composed of hydrophilic peptide bonds and lipophilic fatty chains, and palmitate is usually linked to proteins through covalent modification. This ingredient can significantly promote the migration and proliferation of dermal fibroblasts, while promoting the synthesis of matrix macromolecules (such as elastin, collagen, etc.), thereby enhancing the skin's repair ability. In addition, palmitoyl hexapeptide can also guide fibroblasts and monocytes to migrate to specific parts to achieve wound repair and tissue regeneration. This ingredient is mainly used in the preparation of beauty anti-wrinkle products to reduce fine lines and wrinkles by promoting the production of collagen and inhibiting the activity of collagen degrading enzymes.
