For your skin
A safer, slower-acting alternative to prescription-strength dark-spot faders. Built for long-term use without irritation.
Want the science? Keep reading ↓Mechanism of action
Hydroquinone-glucoside that competitively inhibits tyrosinase without releasing free hydroquinone.
Why we tier this moderate
9 cited papers across 3 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
