Mount Sinai Dermatology offers a wide range of skin health services, with a recently opened dermatology and rheumatology clinic offering care for psoriatic arthritis and other autoimmune conditions. This dermatology center is one of the world's best for treating psoriasis. Here you'll find the same treatments you'll find at most other psoriasis care facilities such as topical ointments, phototherapy, biologics and more. However, Mount Sinai also has excimer lasers at most of its campuses that can treat areas of the skin that have been damaged by psoriasis plaques. The center also employs specialists who work with people who have psoriasis on specific parts of the body, such as the hands and feet. Mount Sinai is also active in the research of new biologic therapies and offers numerous clinical trials as a result.
