What is Acetyl Tetrapeptide-3?Acetyl Tetrapeptide-3 (short for Acetyl Tetrapeptide-3, AT-3) is a water-soluble biomimetic signal peptide and the core active ingredient of Capixyl™, a well-known hair care complex. In vitro, it mimics human signal peptides to stimulate fibroblasts to synthesize type III collagen, type VII collagen and laminin, reinforcing the epidermal-dermal junction structure, boosting hair follicle anchoring capacity and extending the hair growth phase. In formulations, it helps maintain hair follicle stability and assists in improving the sparse appearance of eyebrows and eyelashes. Meanwhile, it can promote dermal collagen production to help maintain skin firmness in skincare formulas.
