Science
Mechanism of Action
SH-POLYPEPTIDE-76, often identified as Nicotiana Benthamiana Hexapeptide-40 SH-Polypeptide-76, is a sophisticated fusion peptide produced in Nicotiana benthamiana plants. It combines Hexapeptide-40 with a recombinant human peptide engineered to mirror Transforming Growth Factor Beta-2 (TGF-β2). This unique structure enables it to act as a plant-based retinoid alternative, signaling the skin to activate its natural repair mechanisms. Specifically, it promotes fibroblast proliferation and stimulates the synthesis of type I collagen and epidermal lipids, essential for robust skin structure and barrier function, leading to enhanced skin condition, improved texture, and sustained hydration.

Stability
This peptide demonstrates enhanced chemical stability compared to traditional retinoids, positioning it as a robust alternative suitable for both daytime and nighttime applications without degradation concerns.
Safety
Safety Profile
Generally considered safe for topical cosmetic use, plant-based polypeptides are typically well-tolerated with a low risk of irritation or allergic reactions. EWG rates its cancer concern as 'Low', with 'unknown/unassessed' for immune effects. As with any new ingredient, a preliminary patch test is advised. Data on safe usage during pregnancy and breastfeeding is limited; professional medical consultation is recommended for these populations.
