Tripeptide-13

Tripeptide-13 is a short chain peptide—a fragment consisting of three amino acids linked together. Peptides are naturally occurring in the body and play important roles in skin structure and function. In skincare formulations, Tripeptide-13 is used as a skin conditioning agent.The ingredient functions primarily to help maintain skin's moisture balance and support the skin's natural barrier. Peptides in general have been studied for their potential to influence skin firmness and elasticity, though individual peptides vary in their specific mechanisms and efficacy.

Tripeptide-13 works as a humectant and conditioning agent, drawing moisture into the skin and helping to lock it in place. Peptides can penetrate the outer layers of skin and interact with existing proteins, potentially signalling to skin cells to maintain or support collagen and elastin production—the primary structural proteins responsible for skin's firmness and suppleness.The precise mechanisms vary between different peptides, and research specifically on Tripeptide-13 remains limited in the published literature. Its conditioning effect is its most established function.

Tripeptide-13 is typically found in serums, moisturisers, and treatment products. Use as directed on the product label. As a conditioning agent, it integrates well into most skincare routines and can be layered with other actives. For best results, apply to clean skin and allow time for absorption before applying subsequent products.

Tripeptide-13 is generally well-tolerated and considered safe for topical use. Allergic reactions are uncommon but possible with any ingredient; patch test if you have particularly sensitive skin.
