1.MECHANISM OF ACTION
Tetrapeptide-14 penetrates the epidermis and acts on dermal fibroblasts to stimulate the synthesis of key structural proteins such as collagen and elastin, enhancing the density and organization of the extracellular matrix. It also modulates signaling pathways involved in matrix degradation, helping to reduce the breakdown of existing collagen and elastin fibers, thereby improving skin firmness and reducing the appearance of wrinkles over time.
2.PRODUCT INDICATIONS
This peptide is indicated for research and development of topical cosmetic formulations aimed at improving skin firmness, elasticity, and reducing signs of aging in mature, photoaged, and sagging skin. It is used in products such as anti-aging serums, firming creams, and eye contour treatments, as well as in in vitro and ex vivo models to evaluate collagen synthesis, skin elasticity, and wrinkle reduction in aged skin conditions.
