Though psoriasis patches appear on the skin, the disease actually starts inside the body. Psoriasis is an autoimmune disease that causes the immune system to send out faulty signals, which makes skin cells multiply faster than normal.
An overactive immune system causes skin cells inside the body to multiply faster than normal, leading to inflammation.
As skin cells build up, they appear on the skin as red, raised patches.
The cells die and take on a silvery, scaly look associated with psoriasis.
Though there’s no cure for psoriasis, there are treatment options that can help make it easier to live with.
