Diet can play a supportive role in managing melasma by promoting overall skin health and reducing inflammation, which may help minimize pigmentation. While diet alone may not directly treat melasma, certain nutrients can help protect the skin and enhance the effectiveness of other treatments. Antioxidants, such as those found in vitamin C-rich foods like citrus fruits, berries, and leafy greens, can support skin health by reducing oxidative stress, which can trigger melanin production. Omega-3 fatty acids found in fatty fish, flaxseeds, and walnuts can also reduce inflammation, potentially improving the skin's response to treatment.

In addition to antioxidants and omega-3s, staying hydrated by drinking plenty of water can help maintain skin moisture and support overall skin function. A balanced diet that includes vitamins and minerals essential for skin repair, such as zinc, vitamin E, and selenium, can further enhance skin regeneration and help reduce the appearance of dark spots. Although diet alone cannot cure melasma, making healthy food choices can complement other treatment methods and protect the skin from further damage. It's important to pair a nutritious diet with other preventive measures, such as sun protection, for the most effective management of melasma.
