Benefits of Alpha-Arbutin for Skin

Gentle on skin: While other skin brightening agents can dry and irritate the skin, arbutin is less irritating.
Improves uneven complexion: Since arbutin inhibits tyrosinase, an enzyme that helps with melanin production, it can prevent dark spots or even help fade them, leading to a more even complexion.
Safe to use with other skincare products: There are no known negative interactions between arbutin and other skincare ingredients.
Effective at fading scars: Much like its ability to fade dark spots, arbutin is also great at fading those red-purple acne scars that stick around long after a zit is gone.
Brightens skin: As explained above, arbutin prohibits the formation of dark spots, offering a brightening effect on the skin.
