What is Psoriasis?

Psoriasis is a condition that causes the body to produce new skin cells more quickly than is normal (in days as opposed to weeks). As a result, these cells may build up on top of one another, resulting in patches that appear thick or scaly. These are called plaques. Although there are many types of psoriasis, the most common form of psoriasis is plaque psoriasis, which affects between 80% to 90% of psoriasis patients.
