Sunspots are mainly caused by prolonged exposure to ultraviolet radiation (UVA/UVB). When the skin is exposed to sunlight, melanocytes are stimulated to produce melanin as a natural defense mechanism. However, when melanin accumulates in the outer layer, dark spots begin to form.
How to Prevent Sunspots:
Use a broad-spectrum sunscreen with SPF 50 to block both UVA and UVB rays. Reapply every two hours, especially during outdoor activities, as sweat or water can reduce protection.
Combine this with physical sun protection—such as hats, long sleeves, and avoiding direct sunlight during peak hours.
In addition, using skincare products with brightening and hydrating ingredients helps repair the skin barrier, reduce pigmentation, and maintain a fair, radiant complexion.
