“Arbutin is a molecule extracted from the bearberry plant that prevents the formation of melanin,” Lin explains. He compares arbutin to two other gentle brighteners: kojic acid (derived from mushrooms) and licorice root (derived from the licorice plant). “[They] are derived from different natural ingredients, but they all function as tyrosinase inhibitors to provide skin lightening and brightening effects,” he says. Basically, brown spots come from pigments that are produced in cells called melanocytes, which contain enzymes called tyrosinase.
They can activate anytime they come in contact with UV light, which is why you’ll notice freckles and sun spots starting to develop if you spend too much time in the sun. That’s when arbutin comes in—it blocks tyrosinase and keeps dark spots at bay.
It's important, however, to learn how to distinguish between alpha-arbutin (the good stuff) and other, similar-sounding ingredients, notes King. "There's beta-arbutin, which is a cheap version and not stable, thus it is important to distinguish the forms of arbutin," she notes.
Arbutin is a widely used skin lightening agent derived from hydroquinone. It is all-natural and can be extracted from bearberry, cranberry, blueberry, and pears. However, synthetical production is also possible through the action of acetobromoglucose on hydroquinone.
Arbutin’s power in reducing hyperpigmentation has been proven and confirmed by various studies over the years. A 2018 study published in Cosmetic Facial Surgery found that arbutin effectively reduced melanin content to approximately 39 percent.
Aside from skin lightening, arbutin also has antioxidant properties that improve skin texture. It’s also used in anti-aging products because of this characteristic.
Natural Alpha Arbutin is a great substitute to hydroquinone as a safe and natural alternative for skin lightening. Arbutin is ‘non-phenol’ which means, unlike some chemical ingredients it does not cause damage to the skin through bleaching or chemical burn.
Blocking of melanin synthesis will result in lighter skin.
Effective in reversing problems like freckles, patches from prolonged sun exposure, age spots, and liver spots.
Alpha Arbutin successfully blocks skin’s tyrosinase activity resulting to the prevention of melanin formation. This natural ingredient can be very beneficial in treating melasma characterized by a dark or tan skin discoloration.
Even skin tone. When deeper penetration into skin layers is needed, Alpha Arbutin is then mixed with other active agents to help in skin repair. This will correct many hyperpigmented conditions to have a more even skin quality. Some examples of this condition is vitiligo and linea nigra caused by pregnancy.
