Tripeptide-10 Citrulline

Product Description

Tripeptide-10 Citrulline is a synthetic tetrapeptide that mimics decorin, a protein that regulates collagen fibrillogenesis, enhancing skin firmness and elasticity. It promotes uniform collagen fibril diameter and spacing, improving skin suppleness and resilience, particularly in anti-aging formulations. Its key benefits include stimulating collagen synthesis (types I, III, and IV) and controlling fibril growth to prevent excessive collagen aggregation, which can lead to skin sagging. Widely used in serums, creams, and lotions, it reduces wrinkles and fine lines, with studies showing a 54% increase in skin elasticity after 28 days of use. Tripeptide-10 Citrulline also supports skin hydration by potentially reducing transepidermal water loss (TEWL), though further research is needed. Suitable for all skin types, including sensitive skin, it is typically used at 0.5-5% concentration in cosmetics for optimal efficacy.
