What is alpha arbutin?
Arbutin is a natural compound found in plants such as bearberry. Alpha arbutin is a lab-made form of this molecule that is considered more stable and more effective than beta arbutin. Chemically it is related to hydroquinone but acts much more gently.
Benefits for skin
Alpha arbutin inhibits tyrosinase in melanin production, slowing the formation of new spots and helping existing ones fade over time. It is used for sun spots and dark marks after breakouts. It usually works better combined with ingredients that act differently, such as niacinamide, vitamin C or tranexamic acid.
How to use it
Apply a thin layer of serum to clean skin over the whole face including the spots, then moisturise. It can be used once or twice a day. Results usually appear in 8–12 weeks. Spot treatment doesn't work without sunscreen: apply broad-spectrum protection every morning and reapply during the day.
Things to watch out for
The EU's scientific safety committee considers alpha arbutin safe up to 2% in face creams; avoid higher-strength products. It is usually well tolerated. Hormone-related pigmentation such as melasma is more complex to treat; talk to your dermatologist. Data on use in pregnancy is limited.
Frequently asked questions
Can you use alpha arbutin with niacinamide?
Yes. They work on dark spots through different pathways, which makes them a popular combination.
Is alpha arbutin hydroquinone?
No. They are chemically related, but alpha arbutin is considered much gentler and safer at cosmetic strengths. Hydroquinone is banned in cosmetics in many countries and used only as a medicine.
Is alpha arbutin good for melasma?
It can be supportive, but melasma is a stubborn condition with hormonal factors. It is best to plan treatment with your dermatologist.
