Formula IngredientSkin Brightening Agent

Alpha-Arbutin

INCI: Alpha-Arbutin

Alpha-arbutin is the synthetic alpha-glucoside form of hydroquinone, and an optical isomer of the naturally occurring beta-arbutin found in bearberry, cranberry, and blueberry plants. It works as a tyrosinase inhibitor, blocking the enzyme responsible for melanin production, thereby reducing hyperpigmentation, dark spots, and uneven skin tone. It is considered a safer and more stable alternative to hydroquinone.

Is Alpha-Arbutin safe? Key considerations

Can Alpha-Arbutin cause irritation?

Low Risk

Alpha-arbutin has an EWG hazard score of 1 (minimal). It is generally well tolerated at concentrations up to 2% in leave-on products. It is considered significantly less irritating than hydroquinone. Rare cases of contact sensitivity have been reported. No EU CosIng Annex II or III restrictions apply, though the EU SCCS has evaluated its safety.

Does Alpha-Arbutin increase sun sensitivity?

Caution Risk

While alpha-arbutin itself does not directly increase photosensitivity, it is a depigmenting agent that reduces melanin (the skin's natural UV defence). SPF 30+ should be used daily during treatment to protect newly brightened skin and prevent re-pigmentation.

Is Alpha-Arbutin safe during pregnancy?

Caution

MANUAL REVIEW: Alpha-arbutin is a hydroquinone derivative. While topical absorption is low and it is generally considered lower-risk than hydroquinone, some dermatologists recommend avoiding hydroquinone derivatives during pregnancy as a precaution. Limited pregnancy-specific safety data available. Consult a healthcare provider.

How does Alpha-Arbutin work?

Individuals with known sensitivity to hydroquinone or arbutin derivatives should review the considerations above before use.
