What it does
Arbutin helps reduce the appearance of pigmentation, such as dark spots. Found naturally in bearberry leaves, arbutin brightens, refines and clarifies the skin for a more even tone. Most skincare now uses alpha-arbutin, a lab-made form that is more stable and effective at lower strengths.
How it works
Arbutin helps brighten the skin and has been widely studied for its effect on the look of uneven tone. It can help fade the look of dark spots and even out skin tone over time, working gradually rather than as a quick fix, so it is best paired with daily SPF to help protect the results. Chemically, it is a hydroquinone molecule bound to a sugar; because it can break down to hydroquinone, EU and Australian rules cap how much can be used in skincare.
MG says
Arbutin is less irritating than many other brightening agents, so it suits sensitive skin. Alpha-arbutin belongs in the targeted-serum step of an evening routine, when actives can work uninterrupted, and you’ll find it among the brighteners in Eighth Day The Eye Renewal Cream, which I tap onto the orbital bone with my ring finger.
Cautions
Generally well tolerated. Brightening results depend on wearing SPF every day. If you’re pregnant, trying to conceive or breastfeeding, check with your doctor, midwife or pharmacist before using arbutin or other brightening actives.
Regional notes
Australia: Alpha-arbutin is limited to 2% in face products and 0.5% in body products, and arbutin to 7% in face products, each with only trace hydroquinone; stronger products are Schedule 6 poisons.
United Kingdom: In the EU, alpha-arbutin is capped at 2% in face creams and 0.5% in body lotions, and arbutin at 7% in face creams (fully in force from 1 November 2025); the UK has not adopted these limits.
