Psoriasis is a chronic skin condition that manifests in different forms. These include plaque psoriasis, guttate psoriasis, inverse psoriasis, pustular psoriasis, and erythrodermic psoriasis.
Scientists believe the hormone hepcidin, when produced in the skin, may be the root cause of psoriasis -- a chronic and sometimes debilitating skin disease that affects 2-3% of the global population.
