Science
Mechanism of Action
This tripeptide acts as an antioxidant, diligently inhibiting oxygen-promoted reactions to safeguard skin components from oxidative stress and deterioration. Beyond its protective role, QUINOYL TRIPEPTIDE-35, or a related 'Peptid4 S-Control' peptide, intervenes directly in skin physiology by blocking the melanocortin 5 receptor (MC5R). This mechanism effectively signals the reduction of sebum production, leading to a balanced, mattified complexion and a visible minimization of pore sizes.

Key findings
- 01 A specific tripeptide, 'Peptid4 S-Control', demonstrated a 15% reduction in skin oiliness within 4 hours and a significant 30% decrease in sebum production after 14 days of application. These in vitro and in vivo studies also observed a visible reduction in pore sizes.

Formulation
Stability
Synthetic peptides like QUINOYL TRIPEPTIDE-35 can be chemically modified to enhance their proteolytic stability, improving their longevity and efficacy within a formulation.
Safety
Safety Profile
Direct safety assessments by the Cosmetic Ingredient Review (CIR) for QUINOYL TRIPEPTIDE-35 are not available. While other general tripeptides are typically considered safe at low concentrations (e.g., <10 ppm), specific toxicity data for QUINOYL TRIPEPTIDE-35, including GHS classification or oral/dermal/inhalation toxicity, remains undetermined in public records. It is important to note that this peptide is distinct from 'quinoyl tripeptide-1', which has been reported for different properties.

Verdict
QUINOYL TRIPEPTIDE-35 is a valuable peptide, offering targeted benefits for oily skin through seboregulation and pore minimization, alongside general antioxidant and skin-protecting properties, though more specific safety and formulation data would further solidify its profile.
