Psoriasis is a chronic inflammatory condition that causes raised, scaly, silvery plaques on the skin’s surface. It does not always result in scarring, but it can if the itching is extreme and the person scratches the region. Although psoriasis does not cause scars, the lesions can be itchy and cause a person to scratch them. The skin might also become dry, cracking, and breaking. Both of these causes have the potential to cause scarring, and any scars that develop are permanent.
