Pal-KTTK is a synthetic lipopeptide consisting of a short peptide sequence (Lys-Thr-Thr-Lys, KTTK) linked to a palmitoyl (Pal) fatty acid. This design enhances the peptide’s stability and allows better penetration into the skin, making it highly effective in cosmetic applications.
Pal-KTTK is primarily used for anti-aging and skin repair purposes. It works by stimulating collagen and elastin synthesis in the skin’s extracellular matrix, which helps improve firmness, elasticity, and overall skin texture. Additionally, it can reduce the appearance of fine lines and wrinkles and support skin regeneration and hydration.
 
Applications: Used in anti-aging and skin-repair products such as serums, creams, lotions, and eye treatments to stimulate collagen and elastin synthesis, improve skin firmness, reduce fine lines and wrinkles, and enhance overall skin texture and hydration.
