Psoriasis is a disorder of the immune system that leads to accelerated growth of skin cells. The most frequent type, known as plaque psoriasis, involves this quick cell reproduction that results in dry and scaly patches.

  • Injury to the skin can come in many forms, for example, a cut or scrape, a bug bite, or an extremely unpleasant sunburn.
