Skin lightening serum is designed to reduce the appearance of hyperpigmentation and lighten the skin. The serum works by inhibiting the production of melanin, the pigment that gives color to the skin. This can help to reduce the appearance of dark spots, age spots, and other forms of hyperpigmentation. In addition, some skin lightening serums also contain ingredients that help to exfoliate and brighten the skin, resulting in a more even, radiant complexion. Apply pea-sized amount on cleansed skin (Face & Neck) on affected areas in the morning and evening. Massage in circular motion for better absorption. Can be used along with other serums and followed with moisturizer. Safe for daily use under makeup.
