Role: ASSETS

Family: ALPHA-ARBUTIN

Comedogenic index: 0

Alpha-arbutin is a plant-derived or synthetic ingredient known for its ability to brighten skin, reduce discoloration and promote even skin tone. It is produced from hydroquinone and the alpha form of the glucose molecule.

Alpha-arbutin acts by interfering with the activity of tyrosinase, an enzyme responsible for melanin production, helping to reduce spots and discolorations on the skin. It also has antioxidant properties, neutralizing free radicals and strengthening the skin's natural defenses.

Alpha-arbutin is an optical isomer of natural arbutin (or beta-arbutin).
Arbutin is a compound with a chemical structure in which a D-glucose molecule is linked to hydroquinone. Arbutin is mainly found in bearberry and pear, while α-arbutin is a compound of hydroquinone and the α-anomer of D-glucose. There are two isomers of arbutin: alpha-arbutin (not found in nature) and beta-arbutin (naturally occurring). Alpha-arbutin and beta-arbutin have similar properties, notably in terms of antioxidation, skin lightening and conditioning.

Arbutin was first isolated from bearberry leaves in 1852.
