Tetrapeptide-21 Solution is a novel bioactive and pure tetrapeptide with anti-aging properties based on the skin's own structures for use in skin care formulations. It activates collagen production and therefore stimulates dermal filling, repair and renewal mechanisms of the skin.
Formulations with Tetrapeptide-21 Solution lead to an increased elasticity and a decreased volume of wrinkles and fine lines. Those formulations containing 100 ppm (about 5% usage rate) Tetratrapeptide-21 Solution showed a 25% improvement in skin roughness and depth of fine and coarse wrinkles.
It is an ideal active ingredient to prevent and minimize the appearance of skin aging based on its collagen boosting activity, outperforming the current market standard (Matrixyl).
Tetrapeptide-21 Solution is a preservative-free peptide solution. The cosmetic raw material should be kept under refrigeration until used in a properly preserved cosmetic formulation.
Tetrapeptide-21 Solution is suitable for oil-in-water and water-in-oil formulations claiming anti-aging and anti-wrinkle properties.
