Science
Mechanism of Action
Tripeptides generally operate by signaling skin cells to engage in crucial biological processes, including the synthesis of key structural components. They stimulate fibroblasts, leading to increased production of collagen and elastin, which in turn enhances skin firmness and elasticity while visibly diminishing fine lines and wrinkles. Beyond structural support, tripeptides are also understood to promote the synthesis of hyaluronic acid for augmented hydration and to fortify the skin barrier, reducing transepidermal water loss. Some specific tripeptides can also help regulate melanin production for a more uniform skin tone and contribute to cellular repair mechanisms.

Formulation
Stability
The optimal pH range for TRIPEPTIDE-50's stability is not specifically documented. Peptides generally exhibit stability around a neutral pH, such as pH 7.4. It is noted that certain copper tripeptides (e.g., Copper Tripeptide-1) can become ineffective under strongly acidic conditions.
Conflicts
- Strong acids (e.g., lactic acid, salicylic acid, fruit acid, mandelic acid, lactobionic acid, malic acid) (Note: specifically for Copper Tripeptide-1)
- VA alcohols and derivatives (Note: specifically for Copper Tripeptide-1)
- VC (ascorbic acid) and derivatives (Note: specifically for Copper Tripeptide-1)
Safety
Safety Profile
TRIPEPTIDE-50, as a distinct INCI name, has not been directly assessed by the CIR Expert Panel or SCCS. However, closely related peptides like Tripeptide-1, Palmitoyl Tripeptide-1, and Palmitoyl Tetrapeptide-7 have been reviewed by CIR and deemed safe for cosmetic use within current practices and concentrations, typically below 10 ppm. No specific FDA status for cosmetic TRIPEPTIDE-50 was identified.
