Science
Mechanism of Action
This potent peptide acts by activating latent Transforming Growth Factor-β (TGF-β), which subsequently signals fibroblasts to significantly increase the production of essential extracellular matrix (ECM) components, including collagen I and collagen III, and elastin. This cascade promotes ECM recovery and tissue remodeling, leading to firmer, more elastic skin. Beyond its structural benefits, it actively reduces melanin production to brighten skin tone and prevent pigmentation, boosts natural moisturizing factors like hyaluronic acid to enhance hydration, strengthens the skin barrier, and supports skin cell regeneration and tissue repair while mitigating inflammation.

Stability
The palmitoyl modification of this peptide is crucial for its enhanced stability within cosmetic formulations, ensuring prolonged effectiveness and delivery of its benefits.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated a group of related palmitoyl oligopeptides, including fatty acyl derivatives of tripeptides, and determined them to be safe for use in cosmetic products at current concentrations. Palmitoyl Tripeptide-37 aligns with these assessed ingredients and is generally considered non-irritating for most skin types at recommended doses.
