Alpha arbutin works to inhibit tyrosinase, an enzyme involved in the production of melanin. When melanin reacts with UV light, it causes freckles, age spots and sun spots. Arbutin can combat these dark spots and the uneven skin tone they cause. It's also a good choice for those who want to fade acne scars or minimise redness from breakouts.
Arbutin is a skin brightener derived from natural ingredients. It's usually extracted from the bearberry plant, although it's found in blueberries and cranberries as well. Alpha arbutin is the most stable form, more effective than naturally-occurring or beta arbutin.
Arbutin is generally safe for all skin types, and can be used with other creams and serums. Be sure that you're using alpha arbutin, other types such as beta arbutin are cheaper but much less potent.
