Psoriasis: What is it and how to treat it
What is psoriasis?
Psoriasis is a common, chronic skin condition that affects millions of people worldwide. It is characterized by red, scaly patches on the skin, which can be itchy and painful. Psoriasis can occur anywhere on the body, but it is most commonly found on the elbows, knees, and scalp.
What causes psoriasis?
The exact cause of psoriasis is unknown, but it is thought to be an autoimmune condition, in which the body's immune system mistakenly attacks healthy skin cells. This causes the skin cells to grow too quickly and build up on the surface of the skin, forming the characteristic red, scaly patches.
How is psoriasis treated?
There is no cure for psoriasis, but there are a number of treatments that can help to manage the condition and reduce symptoms. These treatments include:
- Topical treatments, such as creams and ointments that are applied directly to the skin
- Oral medications, such as methotrexate and cyclosporine
- Light therapy, which involves exposing the skin to ultraviolet light
- Biologic therapies, which are newer medications that target the immune system
The best treatment for psoriasis will vary depending on the individual patient and the severity of their condition.
