Psoriasis is a perpetual skin disorder that affects at least 6 million people in the United States. This skin inflammation and scaling is driven by the immune system, which contains a T-cell, a type of white blood cell. When psoriasis occurs, T-cells mistakenly stop protecting the body against virus and illness and become too active to work properly. The over-activate T-cells also cause the rapid turnover of skin cells, which results in severe skin inflammation.

Typical symptoms of psoriasis are skin thickness, redness, a sore and / or itchy sensation, and the appearance of silvery scales. If you're experiencing any of these symptoms, consult a physician before the symptoms become too severe.

Psoriasis most frequently occurs on the elbows, knees, scalp, face, palms, soles, lower back and legs, but it can appear anywhere, including the fingernails, the toenails, the soft tissues of the genitals and the insides of the mouth.

Psoriasis mostly affects adults - both male and female. Studies have shown that a family history of psoriasis is one of the main influences. Infections, stress, consuming a certain diet or medication, as well as changes in weather can worsen psoriasis.

Light therapy is a common treatment for people with psoriasis. UV light can cause skin damage, but in this case it helps to kill the over-activated T-cells and decrease cell turnover and swelling. Also, some prescription creams and ointments are useful to encourage the skin to peel and unclog pores.
