An anti-pigmentation serum is a specially formulated skincare product designed to help reduce the appearance of dark spots, uneven skin tone, and other types of hyperpigmentation on the skin. These serums typically contain a variety of active ingredients such as vitamin C, niacinamide, kojic acid, and alpha arbutin that work together to inhibit the production of melanin in the skin, which is responsible for causing pigmentation. Regular use of an anti-pigmentation serum can help to brighten and even out the skin tone, leaving the skin looking more radiant and youthful.
