Psoriasis is a chronic skin condition where the skin makes new cells in days rather than weeks. This causes an accumulation of cells creating thickened, silvery-white scaly plaques on the skin’s surface. Typically seen on the scalp, knees, elbows and torso, these plaques can be found anywhere on the body including the nails and joints. In some cases, pustules can develop.
Genetic and environmental factors affect the severity of flare-ups and remissions. Psoriasis can have a substantial impact on self-esteem and depression.
