Psoriasis is a chronic, benign, inflammatory disease of the skin where the skin grows much faster than it otherwise would.Because of that very, very rapid growth, it can't exfoliate off like normal skin can. It's growing 1 times faster than normal skin.So because of this, all this sort of thick, adherent scale sticks on the skin.The extent of skin involvement in psoriasis can range from small, minute patches to very, very large areas of the body, sometimes covering over 5 percent of the entire body surface area.
