TETRAPEPTIDE-45

Description

Tetrapeptide-45 is an innovative synthetic peptide designed to address multiple skin concerns, particularly focusing on improving skin elasticity and firmness. This small molecule consists of four amino acids strategically sequenced to mimic natural skin-signaling mechanisms. Its primary function is to stimulate the production of key extracellular matrix components, including collagen, elastin, and hyaluronic acid.

Clinical studies have demonstrated Tetrapeptide-45's efficacy in reducing the appearance of fine lines and wrinkles, enhancing skin texture, and promoting a more youthful complexion. The peptide works by activating fibroblasts, the cells responsible for producing structural proteins in the skin. This activation leads to increased synthesis of essential skin-supporting elements.

Tetrapeptide-45 is typically incorporated into advanced anti-aging formulations at concentrations ranging from 0.5% to 2%. It is compatible with various cosmetic bases and can be combined with other active ingredients for synergistic effects. The peptide is stable in formulations with a pH range of 4 to 8 and is suitable for use in leave-on products such as serums, creams, and lotions. Regular application of products containing Tetrapeptide-45 can contribute to improved skin elasticity, reduced sagging, and an overall more refined skin appearance.
