The term pigmentation literally means any form of pigment (or colour) that appears on the skin.
The term is most commonly used however to refer to the brown pigmentation – melanin – that occurs on the skin as we age. It is almost always associated with sun damage in the past. A lot of people underestimate how much sun exposure they have however it is the cumulative effect of the sun, over a great number of years, that finally results in the characteristic appearance of sun damaged skin. The best treatment option will depend on the extent of the sun spots, and the other associated signs of ageing that are also present.
