Science
Mechanism of Action
Functions as a multi-modal bioactive that scavenges Reactive Oxygen Species (ROS) and chelates transition metals to halt oxidative chain reactions. It suppresses melanogenesis by inhibiting tyrosinase activity and protects the dermal matrix from UV-induced aging by modulating Nrf2/HO-1 pathways and inhibiting Matrix Metalloproteinase-1 (MMP-1), the primary enzyme responsible for collagen breakdown.
Research
Clinical Evidence
Medium confidence0.01%
Key findings
- 01 In vivo testing of caffeoyl-peptide analogs at a 1% formulation level (using a 100ppm active solution) demonstrated an 8.5% reduction in the melanin index over a 28-day period.
- 02 In vitro data confirms potent tyrosinase inhibition and significant ROS scavenging capacity at concentrations as low as 10 ppm.
Transparency
Dusting Analysis
Due to its high potency at parts-per-million (ppm) levels, this ingredient is frequently 'dusted' in formulations at trace amounts to claim benefits. While effective at low doses, concentrations below 0.1% of a standard commercial peptide solution often fail to provide the targeted physiological response seen in manufacturer data.
The Formula
Formulation
Stability
Stable in aqueous systems within the 4.5–6.5 pH range. Susceptible to peptide hydrolysis at extreme pH levels and oxidation of the caffeoyl moiety if exposed to light or temperatures exceeding 30°C.
Synergies
- Vitamin C (stabilization)
- Sunscreen filters (photo-protection boosting)
- Niacinamide (enhanced brightening)
Conflicts
- Strong oxidizing agents
- Proteolytic enzymes
- Strong acids
- Strong bases
Safety
Safety Profile
While not specifically reviewed by the CIR, its structure as a short-chain peptide is consistent with other peptides generally recognized as safe for cosmetic use under 100 ppm active material.
