Arbutin

Arbutin is antioxidant that may be derived from plants (most commonly the bearberry plant) or made in a lab. The plant-derived form is known as beta-arbutin and the synthetic forms are alpha-arbutin and deoxyarbutin. Each is backed by research for addressing hyperpigmentation issues (i.e. fading dark spots and other discolourations), as well as improving skin’s overall radiance. Arbutin’s main benefit comes from the fact that it naturally breaks down into hydroquinone (which is known to inhibit excess melanin). This allows it to even out skin tone and minimise blotchy/patchy spots that are caused by factors such as unprotected sun exposure. Studies have shown the synthetic derivatives alpha-arbutin and deoxyarbutin are more effective in this regard than the pure natural form of beta-arbutin due to having better stability, longer efficacy, and no risk of sensitivity when exposed to human skin cells. As a raw material, arbutin comes in powder form, with a colourless to faint yellow appearance. The Scientific Committee on Consumer Safety recognises up to a 2% concentration of alpha-arbutin and 7% concentration of beta-arbutin as safe in facial skin care products.
