Arbutin as a Skin Depigmenting Ag…ioxidant Properties.

Arbutin is a skin-lightening ingredient that works by blocking melanin production and has antioxidant properties. It's generally safe with rare side effects, but the research shows it works better when combined with other ingredients or laser treatments. One important caveat: arbutin can break down into hydroquinone during product use, so formulation quality matters.
