CAS: 84380-01-8

INCI: Alpha Arbutin

Chemical Structure:

  • Alpha arbutin is a glycosylated hydroquinone, and its chemical name is 4-[(1R)-2,4-dihydroxy-3-methylbutyl]phenyl β-D-glucopyranoside.
  • The chemical formula is C12H16O7.

Natural Source:

  • Alpha arbutin is derived from the bearberry plant (Arctostaphylos uva-ursi), as well as some other plants like cranberries, blueberries, and pear skins.
  • It is a more stable form of arbutin compared to beta arbutin.

Skin-Brightening Properties:

  • Alpha arbutin is known for its skin-brightening and lightening properties. It works by inhibiting the activity of tyrosinase, an enzyme involved in the production of melanin (the pigment responsible for skin color).
  • By reducing melanin production, alpha arbutin helps to even out skin tone and reduce the appearance of hyperpigmentation, dark spots, and discolorations.


  • Alpha arbutin is considered more stable than beta arbutin, making it a preferred choice in cosmetic formulations.
  • Its stability allows for a longer shelf life and better efficacy in skincare products.


  • Alpha arbutin is generally considered safe for use in skincare products when used in recommended concentrations.
  • It is often used as an alternative to hydroquinone, a compound with similar skin-brightening properties, but with potential side effects.


  • Alpha arbutin is compatible with various skincare formulations, including creams, serums, lotions, and masks.
  • It can be combined with other skincare ingredients for enhanced benefits, such as antioxidants and moisturizing agents.

Usage Instructions:

  • Skincare products containing alpha arbutin are typically applied topically to the skin.
  • Users are advised to follow the product instructions and incorporate it into their skincare routine as recommended.


  • Addresses hyperpigmentation: Alpha arbutin is effective in reducing the appearance of dark spots, sun spots, and other forms of hyperpigmentation.
  • Skin brightening: Regular use of alpha arbutin can contribute to a more radiant and even complexion.


  • While alpha arbutin is generally well-tolerated, individuals with sensitive skin should perform a patch test before using products containing this ingredient to ensure there is no adverse reaction.
