Mechanism of action

Contains glabridin and liquiritin; inhibits tyrosinase and quenches inflammatory cytokines without affecting cell viability.

Why we tier this moderate

9 cited papers across 5 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.
