Psoriasis is a common skin condition that changes the life cycle of skin cells. Psoriasis causes cells to build up rapidly on the surface of the skin. The extra skin cells form thick, silvery scales and itchy, dry, red patches that are sometimes painful.
Psoriasis is a persistent, long-lasting (chronic) disease. There may be times when your psoriasis symptoms get better alternating with times your psoriasis worsens.
The primary goal of treatment is to stop the skin cells from growing so quickly. While there isn't a cure, psoriasis treatments may offer significant relief. Lifestyle measures, such as using a nonprescription cortisone cream and exposing your skin to small amounts of natural sunlight, also may improve your psoriasis symptoms.

Seek medical advice if your signs and symptoms worsen or don't improve with treatment. You may need a different medication or a combination of treatments to manage the psoriasis.
