Can light therapy help treat acne?

Dr. Mehmet Oz, MD

If you are considering a cosmetic procedure or treatment, you should consult a dermatologist about which one is right for you. Phototherapy, such as blue-light therapy and pulsed-light therapy, can help treat acne by killing acne-causing bacteria and shrinking the sebaceous glands, which make the sebum that can clog pores. Light can be used alone or in combination with other heat-generating devices that deliver heat deep within the tissue, or with chemicals that increase the skin's sensitivity to light. The light doesn't use potentially damaging wavelengths such as ultraviolet light. Treatments are given in a doctor's office by a trained clinician.

Seek a physician’s assistance for medical concerns.
