Psoriasis is a skin disease that causes scaling, inflammation, and dry, cracked skin.
Unlike healthy skin that flakes and rebuilds every 28 to 30 days, psoriatic skin builds upon new skin continuously every 3 to 6 days, and psoriasis lesions form. You may have patches of thickened red areas of skin covered by scales and silvery dead skin. These patches can vary in size. Commonly affected areas include elbows, knees, scalp, back, and stomach, and these areas will itch. To confirm whether your skin is psoriatic, consult with a dermatologist .
