Your skin might get sun-damaged and acquire dark spots (hyperpigmentation). Your hands, arms, or face may have brown patches caused by an accumulation of melanin. Melanin is a pigment that gives color to your skin. These spots are not painful, but if you don’t like these, there are surgeries and topical treatments that you can help with.

Although it takes months and can irritate your skin, topical retinol lightens sun spots in some people. Visit a dermatologist if you are worried about the dark patches or if the topical treatment isn’t working.
