2). The skin does not show any other change.
3). Lesions are usually located on one or more of the following sites, the bridge of nose, both cheeks, upper lip and the forehead.
4). On the forehead a linear area just above the eyebrows is frequently involved, while an area of upper lip below the nose and skin around the eyes are as a rule spared.
5). Precipitating factors for melasma to develop are pregnancy, OC pills and UV light.
