“There are two isomers of arbutin, the alpha and beta forms,” Dobos says. “They differ in structure and properties.” She also states that alpha arbutin is about 10 times more effective than beta arbutin when it comes to skin-brightening effects, which is why so many are reaching for this powerhouse ingredient when it comes to bettering the skin. But since it is a form of hydroquinone, it’s best to steer clear of this ingredient while pregnant and/or breastfeeding. Dobos also adds that even though alpha arbutin is suitable for most skin types, those with sensitive skin may want to avoid using high levels or combining with products containing other potentially irritating ingredients, like retinol. And as always and to no surprise, you’ll want to pair this ingredient (and all other skin care products) with the daily application of a broad-spectrum sunscreen. Not only can sun exposure worsen dark spots and cause new spots to form, but it will help to safeguard the results you may see when using alpha arbutin. But before you buy, it’s always best to consult with your local dermatologist to make sure this ingredient is right for you and your skin concerns.
