Science
Mechanism of Action
This synthetic peptide operates by actively counteracting oxidative stress, thereby safeguarding skin cells from potential damage. Beyond its direct antioxidant action, TRIPEPTIDE-66, like other functional peptides, participates in the skin's natural metabolic signaling pathways, encouraging the skin to initiate and support its inherent repair mechanisms.

Stability
While a specific optimal pH for TRIPEPTIDE-66 is not explicitly documented, peptides in general often exhibit enhanced stability in buffer solutions within a pH range of 3 to 5. This range is known to help mitigate deamidation and oxidation, and can provide protection for disulfide bridges. Effective peptide formulation strategies typically involve careful selection of buffers, incorporation of excipients like amino acids or sugars, minimizing air exposure, maintaining low temperatures, and providing protection from light.
Safety
Safety Profile
Comprehensive safety evaluations by regulatory bodies such as the Cosmetic Ingredient Review (CIR), SCCS, or FDA specifically for TRIPEPTIDE-66 are not publicly available. Industry sources indicate that this ingredient is currently 'not rated' due to a lack of reviewed research. The CIR generally notes that the biological activity and, consequently, the safety profile of peptides can vary significantly based on their unique amino acid sequences.
