Science
Mechanism of Action
This phosphinic alanine analogue stabilizes dopachrome and inhibits dopachrome tautomerase (TRP-2). This action prevents eumelanin polymerization, thus interrupting the melanogenesis pathway at a downstream stage.

Key findings
- 01 At 0.1-0.2%, demonstrated up to 25-30% melanogenesis inhibition in reconstructed epidermis models.
- 02 In a 56-day clinical study (n=21), 0.5-1.5% reduced melanin density by up to 70% and increased skin luminosity by up to 8%.
- 03 A 0.5% concentration significantly boosted skin hydration after a single application, maintaining 24-hour moisturization in 95% of participants (n=20).
