Arbutin is a skin-lightening agent that reduces melanin production, but can cause irritation and photosensitivity.
Arbutin is a naturally derived or synthetically produced skin-lightening agent that inhibits tyrosinase, an enzyme responsible for melanin production. It's commonly used topically to reduce hyperpigmentation, even skin tone, and lighten dark spots. While generally safe, potential side effects include mild skin irritation and increased photosensitivity. Proper sun protection and adherence to recommended concentrations are essential when using arbutin.
Key Information
Outside Body Harmful Score
Common Dosage
Typically found in topical creams and serums with concentrations ranging from 0.5% to 2% for alpha-arbutin and up to 7% for deoxyarbutin (though this is less common). Dosage depends on the specific product and formulation.
Source Type
natural
Production Process
Arbutin is extracted from various plants, including bearberry, cranberry, and blueberry. It can also be synthesized chemically.

Outside BodyPotential Benefits
Skin brightening aims to lighten skin tone and reduce hyperpigmentation through melanin inhibition, exfoliation, and protection against UV damage. This results in a more even and radiant complexion.
Antioxidants protect cells from damage caused by free radicals, reducing inflammation, and promoting overall health. They neutralize these unstable molecules by donating electrons and preventing them from damaging cellular structures.
Arbutin lightens the skin by inhibiting tyrosinase, reducing melanin production and promoting a more even skin tone. It helps fade hyperpigmentation, sunspots, and melasma.
Possible Side Effects
Skin irritation involves symptoms like redness, itching, and rashes due to contact with irritants, allergens, or environmental factors. Severity varies based on the cause, individual sensitivity, and affected area; persistent cases may lead to secondary infections.
Photosensitivity is an increased sensitivity to UV radiation, leading to sunburn, rash, or blistering. Reactions can be phototoxic or photoallergic, with symptoms ranging from mild redness to severe blistering and potentially increasing skin cancer risk with prolonged exposure.
Scientific Evidence
Several studies demonstrate arbutin's efficacy in reducing melanin production and hyperpigmentation. Research has focused on its mechanism of action (tyrosinase inhibition) and comparative effectiveness against other skin-lightening agents. Further research could explore long-term effects and optimal formulations. Specific studies can be found on PubMed using keywords 'arbutin,' 'tyrosinase,' 'melanin,' and 'hyperpigmentation.'
