Detailed answer

Niacinamide, a form of Vitamin B3, helps manage melasma by decreasing the production of melanin, the pigment responsible for causing dark spots. It inhibits the transfer of melanin to the skin's surface and reduces the activity of melanocytes. By regulating melanin production, niacinamide can gradually lighten the dark patches associated with melasma and improve overall skin tone. Additionally, niacinamide has anti-inflammatory properties that can help calm and soothe the skin, reducing redness and irritation often associated with melasma. It is important to note that while niacinamide can be beneficial in managing melasma, results may vary depending on the individual and other factors such as daily sun protection and consistent skincare routine should also be considered.
