Detailed answer

Skin brighteners contain ingredients that target melanocytes, the cells responsible for producing melanin. These ingredients inhibit the enzyme tyrosinase, which is involved in melanin production, leading to a reduction in melanin levels. Additionally, skin brighteners often contain exfoliating agents that help remove dead skin cells and reveal a brighter complexion. This exfoliation process further enhances the skin's radiance and evenness of tone. It is important to note that prolonged and consistent use of skin brighteners, along with sun protection, is usually required to see noticeable results.
