According to Traditional Chinese Medicine, blemished skin in adolescence is caused by heat in the lungs with toxic heat or damp heat in the Yang Ming (Stomach and large intestine) meridian. The first pattern is mainly seen on the chin, the nose, on the sides of the nose and on the forehead. When damp heat is in the Yang Ming meridian, the affected areas are mostly around the mouth and on the cheeks. The pimples/pustules are more distinct and tend to cover the entire face. A mixed form of both patterns often occurs.
