Detailed answer

Kojic acid is a natural skin-lightening agent that helps manage melasma by inhibiting the production of melanin, the pigment responsible for dark spots. It works by blocking the enzyme tyrosinase, which is involved in the synthesis of melanin. By reducing melanin production, kojic acid helps fade existing melasma spots and prevents the formation of new ones. However, it is important to note that kojic acid should be used in conjunction with broad-spectrum sunscreen to protect the skin from further sun damage, as sun exposure can worsen melasma. Additionally, it is advisable to consult a dermatologist before using kojic acid to ensure its suitability for individual skin types and conditions.
