Science
Mechanism of Action
As a multi-peptide complex, this ingredient is postulated to act as a signaling agent, prompting the body to activate the skin's intrinsic repair mechanisms. Peptides are generally understood to foster the regeneration of mature skin, enhance its structural integrity, and contribute to the visible reduction of wrinkles. Within hair care applications, peptides are believed to permeate the inner hair structure (cortex), thereby fortifying and strengthening the hair.

Safety Profile
The specific complex R-TETRAPEPTIDE-38 HEXAPEPTIDE-40 OLIGOPEPTIDE-152 SH-POLYPEPTIDE-106 has not undergone review by the Cosmetic Ingredient Review (CIR), SCCS, or FDA. While a related ingredient, sh-oligopeptide-1, is authorized for general cosmetic use across various concentrations, its long-term safety profile remains uncharacterized, and concerns regarding preclinical bioactivity studies have been noted.
