Detailed answer

Arbutin is a skincare ingredient that helps to treat uneven skin tone by inhibiting the production of melanin, which is responsible for dark spots and hyperpigmentation. It is a natural derivative of the bearberry plant and works as a tyrosinase inhibitor, the enzyme involved in melanin synthesis. By reducing the activity of tyrosinase, arbutin helps to prevent the formation of new dark spots and lightens existing ones. It is a safe and effective ingredient for brightening the skin tone, and it is commonly used in skincare products like serums, creams, and masks. With regular use, arbutin can help to even out the skin tone and promote a more radiant and uniform complexion.
