Tripeptide‑37 is a synthetic lipo‑peptide designed to stimulate collagen and elastin synthesis via activation of TGF‑β pathways, leading to improved skin firmness, elasticity, and a smoother complexion.
It exhibits anti‑aging, wound‑healing, anti‑inflammatory, and antioxidant effects that help condition and revitalize the skin surface.
Safety assessments rate its irritation potential, biochemical toxicity, and allergenicity as low, making it suitable for sensitive skin formulations.
It pairs well with hydrating actives such as hyaluronic acid and antioxidants like vitamin C for enhanced anti‑aging efficacy.

Applications include serums, creams, and essences targeted at anti‑wrinkle, firming, skin repair, and resilience improvement.
It may also support stem cell activation and matrix remodeling in skin tissues.
Regular use over time supports visible reduction in fine lines and enhanced skin texture; results accumulate gradually rather than instantly.
