Science
Mechanism of Action
This phenolamide molecule interrupts the melanogenesis pathway by inhibiting tyrosinase, the primary enzyme responsible for pigment production. Beyond brightening, it acts as a high-performance antioxidant that scavenges superoxide and hydroxyl radicals, shielding dermal structures from degradation and supporting the skin's natural detoxification processes.
Research
Clinical Evidence
High confidence0.1%
Key findings
- 01 Clinical evaluation published in the Journal of Agricultural and Food Chemistry confirmed that a 0.1% concentration provides significant tyrosinase inhibition and radical scavenging activity.
- 02 KISTI stability assessments verified that the molecule maintains 80-90% potency over 90 days in both O/W and W/O emulsions under thermal stress (40°C).
Transparency
Dusting Analysis
Because this ingredient is effective at exceptionally low concentrations (0.1%), brands may include it at trace amounts below 0.01% simply for label claims. For clinical results in brightening and antioxidant protection, a concentration of 0.1% is the established benchmark.
The Formula
Formulation
Stability
Demonstrates excellent thermal stability up to 40°C. However, it is sensitive to UV exposure and alkaline environments; advanced formulations often utilize encapsulation to ensure deep penetration and long-term integrity.
Synergies
- Sunscreen UV filters
- Vitamin E
- Ferulic Acid
- Liposomal delivery systems
Conflicts
- Strong oxidizing agents
- High pH formulations (>7.5)
Safety
Safety Profile
While not yet formally reviewed by the CIR, it is approved for use in the EU (CosIng) and has a long history of safe application in high-end global formulations at concentrations of 0.1% or less.
