Acne Phototherapy Reviews (Light Therapy)

The Science of Acne Phototherapy (Light Therapy)

In 2000, the British Association of Dermatologists published a meta-analysis of the available research on Acne Phototherapy. The study concluded that the UV light from sunlight demonstrated a 70% improvement in moderate acne; however, due to the damaging effects of UV radiation, the authors recommended the milder treatment of blue or red light, which has shown similarly positive effects (50-60% improvement) with fewer risks. In patient trials, blue light was most effective at destroying the P. acnes bacteria near the surface of the skin, while red light was more effective at reducing inflammation. Combinations of red and blue visible light proved most effective. Unlike control patients, who were given Benzoyl Peroxide, patients treated with phototherapy did not report dry, itchy skin or other side effects.

The authors conclude that it is “clearly supported by the data” that “a mixture of blue and red light, and also blue light alone does help acne patients with mild or moderate disease” through “antibacterial and anti-inflammatory action” (Cunliffe and Goulden, 2000). The researchers recommend 15 minutes of light per day on the affected areas.
