Alpha-Arbutin
Alpha arbutin (AA) is a skin care product that's most often used to reduce uneven skin tone and hyperpigmentation.
It's most often extracted from the bearberry plant, which is a plant in the genus Arctostaphylos. It contains beneficial compounds that regulate skin's pigment. It can also be extracted from certain other plants and fruits, including pears, berries and those in the Ericaceae family, as well as made synthetically in a lab. You can use AA on its own — plus you'll find it in some skin care serums, masks and creams. What does alpha arbutin do to your skin? It's considered a "tyrosinase inhibitor" and a natural skin lightener. It works to improve skin's tone and texture by preventing the formation of melanin, which gives skin its pigment.
