Palmitoyl-Pentapeptide-4, more commonly known by its trade name Matrixyl, is a peptide used in skincare formulations to address signs of aging. It’s part of the matrikine peptide family, which plays a key role in repairing and maintaining the skin’s youthful appearance. Peptides are short chains of amino acids, the building blocks of proteins, which can penetrate the skin’s outer layer to send signals to cells to let them know how to function properly.

Matrixyl specifically is made up of a chain of five amino acids linked to a 16-carbon chain (palmitoyl) to increase its oil solubility and thus, its ability to penetrate the skin’s lipid barrier. This design helps it to effectively reach the deeper layers of the skin where it can stimulate the production of collagen and elastin. Collagen and elastin are critical components of the skin’s structure, providing it with firmness and elasticity.

By promoting the synthesis of these essential skin proteins, Palmitoyl-Pentapeptide-4 helps to reduce the appearance of fine lines, wrinkles, and other signs of aging, leading to a more youthful complexion. It’s widely used in anti-aging products, including serums, creams, and lotions, for its efficacy in enhancing skin condition and appearance with regular use.

Beyond its anti-aging benefits, Matrixyl also supports the skin in retaining moisture, improving skin texture, and reducing skin damage, making it a versatile ingredient in skincare formulations aimed at improving overall skin health and appearance.
