Alpha Arbutin

Alpha-ArbutinActive

Hydroquinone derivative for tone-evening. Well-tolerated alternative without hydroquinone's regulatory baggage.

What it does

Alpha arbutin slowly releases hydroquinone in the skin at sub-clinical levels, giving brightening benefit with much better tolerance. Works over 8-12 weeks. Often combined with niacinamide or vitamin C for additive effect.
