A dermatologist is a medical doctor specializing in the diagnosis and treatment of skin diseases involving the skin, hair, nails, and mucous membranes. The name comes from the word "derma" which is the scientific term for skin. A dermatologist may treat skin picking disorder's physical effects including treating wounds, healing scars, alleviating skin irritation, and prescribing medication. A dermatologist may also rule out physical causes for skin picking disorder including allergies, hypersensitivity or other physical causes. Doctors familiar with psychodermatology also understand the connection between stress and the skin. Although dermatologists do not treat the psychological aspects of the disorder, they are an integral member of the treatment team.
