WHAT IS PSORIASIS?
Psoriasis is a medical condition that occurs when skin cells grow too quickly. Faulty signals in the immune system cause new skin cells to form in days rather than weeks. The body does not shed these excess skin cells, so the cells pile up on the surface of the skin and lesions form.
A family history of psoriasis seems to increase the risk of developing psoriasis. It is important to know that a family history of psoriasis does not guarantee that someone will develop psoriasis.
Psoriasis can begin at any age, from infancy through the golden years. There are, however, times when psoriasis is most likely to develop. Most people first see psoriasis between 15 and 30 years of age. About 75% develop psoriasis before they turn 40. Another common time for psoriasis to begin is between 50 and 60 years of age.
