Effect

Suppresses the action of tyrosinase involved in melanin production, curbing melanin production to help prevent dark spots and freckles.

Concentration

EU limits: 2% in face cream and 0.5% in body lotion (2024/996; applies on the EU market from 1 November 2025). Primary data on a typical use level are unconfirmed.

Effect

Suppresses the action of tyrosinase involved in melanin production, curbing melanin production to help prevent dark spots and freckles.

Mechanism

A type of hydroquinone glycoside that competitively inhibits tyrosinase. The alpha-glycoside is said to have higher inhibitory activity than the beta form (arbutin).

Typical concentration

EU limits: 2% in face cream and 0.5% in body lotion (2024/996; applies on the EU market from 1 November 2025). Primary data on a typical use level are unconfirmed.

Onset

Usually gradual over several weeks to several months of continued use. Immediate effect is hard to expect.

Cautions

Under unstable conditions such as high temperature, low pH, or long-term storage, it may decompose and release hydroquinone, so formulation stability must be managed.
