Arbutin

Phytochemical

What is it

Arbutin is a glycoside of hydroquinone found in bearberry (Arctostaphylos uva-ursi), pear, and several other plants. It is used in skin lightening products and traditional urinary herbal preparations.

Evidence for 2 uses

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Skin pigmentation (topical)

Limited Evidence

Topical arbutin can modestly reduce hyperpigmentation through hydroquinone release. Evidence is moderate; results are slower and weaker than direct hydroquinone.

Urinary tract antiseptic (traditional)

Limited Evidence

Traditional use; limited clinical evidence for mild urinary infections. Not a substitute for antibiotics when needed.

How it works

Arbutin is hydrolyzed in the body or by topical bacteria to release hydroquinone, a tyrosinase inhibitor that reduces melanin production in skin. Topically applied arbutin is the basis of many skin-brightening cosmetics. Orally, arbutin from uva ursi is excreted in urine where it can have a mild antiseptic effect; this is the traditional rationale for its use in urinary tract complaints.

Dosage

Topical: 1-5% in cosmetic preparations. Oral uva ursi: 400-840 mg of dried herb up to 3 times daily for short periods. DSLD label data did not include a typical dose for isolated arbutin.

When and how to take it

Topical: typically applied once or twice daily as part of skincare routine. Oral: short courses only, with plenty of water.

3 commercial forms

Compare the main delivery options and what they’re best suited for.

Alpha-arbutin (cosmetic)

Modern cosmetic ingredient.

More potent and stable than beta-arbutin.

Beta-arbutin (natural form)

Found in plant extracts.

Less stable; hydrolyzed by enzymes in skin.

Uva ursi extract (oral)

Traditional herbal use.

Releases hydroquinone in urinary tract.

Safety

Hydroquinone has been linked to skin and possibly systemic toxicity at high doses. Topical arbutin at typical cosmetic concentrations is generally considered safe. Oral long-term use of arbutin-containing herbs is not recommended due to hydroquinone exposure.

Who should be cautious

Avoid oral arbutin and hydroquinone use in pregnancy and lactation. Limit topical use to short-to-medium term and avoid combining with strong exfoliating products without guidance. People with darker skin tones should use only under dermatologist supervision due to risk of paradoxical hyperpigmentation (ochronosis with hydroquinone).

Interactions

May enhance the effects of other tyrosinase inhibitors or skin-lightening agents. Limited oral interaction data.

Frequently asked questions

Is arbutin safer than hydroquinone?⌄

Topically, arbutin's gradual release of hydroquinone tends to produce less irritation than direct hydroquinone, but the underlying mechanism is the same.

Can I take arbutin pills to whiten my skin?⌄

Oral arbutin for skin lightening is not well supported by evidence and exposes you to hydroquinone systemically, which is not recommended.
