Phototherapy
Light therapy is a medical treatment that is used to treat various skin conditions, including acne and psoriasis. Light therapy also is used to help treat mood disorders, such as Seasonal Affective Disorder (SAD).
Various types of light therapy are used to treat numerous skin conditions, including psoriasis, acne, and eczema. The amount of light that is distributed depends on the severity of the condition and the health of the patient.
