Detailed answer

Exfoliation can help improve the appearance of melasma by promoting the shedding of dead skin cells and facilitating the penetration of topical treatments. It removes the top layer of skin, encouraging the turnover of pigmented cells, and may also enhance the effectiveness of brightening ingredients. However, caution must be exercised as excessive exfoliation or aggressive methods can worsen melasma and lead to skin irritation. It is recommended to consult a skincare professional to determine the appropriate exfoliation method and frequency for managing melasma.
