What it is

Arbutin is hydroquinone with a glucose molecule attached, found naturally in bearberry, cranberry and pear leaves and now usually made synthetically. That sugar group makes it gentler and more stable than hydroquinone itself, and skin enzymes release the active part slowly. It is used as a skin-lightening and skin-conditioning agent, and because it is a hydroquinone-releasing substance the EU regulates it specifically.

What it does well

  • Fades dark spots more gently than hydroquinone

    Arbutin inhibits tyrosinase, the enzyme that starts pigment production, so it slows the formation of new pigment rather than bleaching what is already there. Reviews of the mechanism are consistent, but large independent clinical trials in cosmetic use are limited.

    Moderate evidence

  • Also acts as an antioxidant

    Laboratory work shows free-radical scavenging activity alongside the anti-pigment effect. This is a secondary property and has not been shown to matter clinically at cosmetic doses.

    Limited evidence

Worth knowing

  • Releases small amounts of hydroquinone, which the EU explicitly caps

    Skin and bacterial enzymes can cleave arbutin to hydroquinone, a substance banned from EU cosmetics. The EU therefore requires that hydroquinone in an arbutin-containing product stays at unavoidable trace levels and no higher.

    Matters most toAnyone buying arbutin products from outside the EU, where the hydroquinone trace limit and the 7% cap may not be enforced.

  • Skin-lightening actives need diligent sun protection

    Suppressing pigment production without daily sunscreen tends to produce patchy results and lets treated spots return. This is a limitation of the whole category, not a toxicity issue.

    Matters most toAnyone using it for melasma or post-inflammatory marks, particularly on deeper skin tones.

  • Deoxyarbutin, a related molecule, is banned outright

    Tetrahydropyranyloxy Phenol (deoxyarbutin) is listed as a prohibited substance in Annex II of the EU Cosmetics Regulation. Ordinary arbutin and alpha-arbutin remain permitted within their limits.

    Matters most toShoppers comparing imported brightening products that may still list deoxyarbutin.

Where the EU stands

Concentration-restricted

Permitted in face cream up to 7%. Hydroquinone in the finished product must stay as low as possible and no higher than unavoidable trace levels. The restriction was introduced by Regulation (EU) 2024/996 and has applied in full since 1 November 2025.

    Opinion on the safety of alpha-arbutin and beta-arbutin in cosmetic products (SCCS/1642/22)

    SCCS (Scientific Committee on Consumer Safety), European Commission · 2023

    The SCCS concluded that beta-arbutin is safe in face cream up to 7% and that hydroquinone in such formulations should not exceed unavoidable trace levels; this opinion is the direct basis for the EU limit.

    Arbutin as a Skin Depigmenting Agent with Antimelanogenic and Antioxidant Properties

    Antioxidants (Basel) · 2021 · doi:10.3390/antiox10071129

    Reviews the evidence that arbutin reduces melanin by inhibiting tyrosinase and also shows antioxidant activity, while noting that its safety profile is tied to how much hydroquinone it releases.
