Blue light therapy acne treatment is currently being used successfully to prevent and even reverse mild to moderate cases of acne vulgaris. Acne blue light therapy treatments generally are given once a week for four to eight weeks, depending on the severity of the acne and how well the patient responds. A topical cream may be used in addition to the acne blue light treatments to help reduce lesions, pustules, and papules.

One of the main benefits of blue light therapy acne treatment is the minimal incidence of side effects. Acne blue light therapy is very gentle and surrounding tissues are not harmed, unlike other treatments previously employed.
