Melanin is what gives our skin its color. Pigmented lesions are dark in colour simply because melanin is abnormally concentrated in one area of the skin. High concentrations of melanin can be due to various factors. Some types are present at birth, but most occur with age or as a result of overexposure to the sun’s damaging rays.
Lentigines or age spots are premature ageing brown marks, which appear on the backs of hands and the face. Sunburn freckles are the result of sun damage and occur on the back, upper chest and shoulders. Most are harmless but all are ageing and may be unattractive. Although most brown spots are easily ignored, many are quite conspicuous and can detract from your skin’s natural beauty.
