Psoriasis

Psoriasis is an inflammatory disorder in which a flaw within the body triggers the development of new skin cells more quickly than is usual. Psoriasis often manifests itself as patches of red, inflamed, and bumpy skin at different sites over the body.

People with psoriasis often feel embarrassed by the appearance of their skin and try to keep the affected areas covered with make-up or clothing. In many cases, certain types of clothing and social activities – such as bathing suits and swimming – are avoided. In addition to the emotional ramifications, psoriasis can be uncomfortable—even painful, if the skin cracks.

What is Psoriasis?

Psoriasis is a long term, inflammatory skin condition involving the abnormally rapid growth of skin cells. While the usual cycle of growth is 28 to 30 days, in psoriasis a flaw in the immune system signals skin cells to grow in a few days. Excess dead skin piles up.

Psoriasis usually appears on the knees, elbows, lower back, legs and scalp.  The skin may be itchy, dry, and painful and may crack and bleed.  It can also cause broken, crumbling or detached nails.
