Psoriasis is a chronic autoimmune disease that affects the skin. It is characterized by the rapid buildup of skin cells, which leads to the formation of thick, silvery scales and itchy, dry, red patches. This process typically takes days, but in psoriasis, it happens in a matter of days, causing the cells to accumulate faster than they shed.

The exact cause of psoriasis is not fully understood, but it is believed to involve a combination of genetic and environmental factors. The immune system plays a key role, mistakenly attacking healthy skin cells. Psoriasis is not contagious and cannot be spread from person to person.

There are several types of psoriasis, with plaque psoriasis being the most common. Other forms include guttate psoriasis, inverse psoriasis, pustular psoriasis, and erythrodermic psoriasis. The condition can affect any part of the body, but it commonly appears on the elbows, knees, scalp, and trunk.

Psoriasis can have a significant impact on a person's quality of life, causing physical discomfort and emotional distress. While there is no cure for psoriasis, various treatments are available to manage symptoms, reduce inflammation, and slow the growth of skin cells. These treatments can include topical medications, light therapy, and systemic medications. Triggers for flare-ups can vary among individuals and may include stress, infections, certain medications, and skin injuries.
