The skin cells accumulate on the surface of the skin, causing patches of psoriasis to appear. While patches can appear anywhere on the skin, most patches appear on the elbows, knees, back, and scalp. Psoriasis can also affect the nails, leading to pits, crumbling, and separation of the nail plate from the nail bed. Treatment of psoriasis varies from patient to patient and ranges from topical creams and ointments to systemic therapies in some cases. Lifestyle modifications, including proper exercise and a healthy diet, can improve a patient’s psoriasis. While there is no known cure for psoriasis, the providers and staff of Thomas Dermatology can develop a long-term treatment plan that helps you control your psoriasis and improve your quality of life.
