Science
Mechanism of Action
Inhibits tyrosinase enzyme activity to reduce melanin synthesis while simultaneously blocking inflammatory signaling pathways triggered by environmental aggressors. Functions as a dual-action brightener that both prevents new pigmentation formation and soothes existing skin irritation from pollution and light exposure.
Research
Clinical Evidence
High confidence0.2%
Key findings
- 01 Significantly reduced UV-induced pigmentation and maintained skin brightness compared to placebo in Asian subjects (Phototypes II-III)
- 02 Demonstrated tyrosinase inhibition in human epidermal melanoma cells with protection against blue light and pollution-induced hyperpigmentation

Dusting Analysis
With proven efficacy at 0.2% and typical use ranges of 0.1-0.5%, concentrations below 0.05% would likely provide minimal brightening benefits
