Palmitoyl tripeptide-1, as a matrikine signal peptide, exhibits significant anti-wrinkle and anti-aging properties, while effectively improving the texture of the skin. This ingredient exerts its biological effects in the dermis, promoting the synthesis of the extracellular matrix, including collagen and glycosaminoglycans, thereby strengthening the structural integrity of the dermis. The result is an increase in skin thickness and firmness, and wrinkles are significantly reduced. In addition, palmitoyl tripeptide-1 also enhances the skin's protection against ultraviolet radiation.
