The field of laser surgery has changed the horizon for many skin disorders especially acne. Scientist are constantly working on new laser acne treatments to deal with all types of acne prone skin from mild to severe.

Here is the summary of a study conducted by the Unit of Dermatology in the Imperial College of Science, Technology and Medicine in London.  Which trials different color laser lights in the treatment of acne.

Summary of Laser Acne Treatments:

In this study we have evaluated the use of blue light (peak at 415 nm) and a mixed blue and red
light (peaks at 415 and 660 nm) in the treatment of acne vulgaris. One hundred and seven patients
with mild to moderate acne vulgaris were randomized into four treatment groups: blue light, mixed
blue and red light, cool white light and 5% benzoyl peroxide cream. Subjects in the phototherapy
groups used portable light sources and irradiation was carried out daily for 15 min. Comparative
assessment between the three light sources was made in an observer-blinded fashion, but this could
not be achieved for the use of benzoyl peroxide. Assessments were performed every 4 weeks. After
12 weeks of active treatment a mean improvement of 76% (95% confidence interval 66±87) in
inflammatory lesions was achieved by the combined blue±red light phototherapy; this was
significantly superior to that achieved by blue light (at weeks 4 and 8 but not week 12), benzoyl
peroxide (at weeks 8 and 12) or white light (at each assessment). The final mean improvement in
comedones by using blue±red light was 58% (95% confidence interval 45±71), again better than
that achieved by the other active treatments used, although the differences did not reach significant
levels. We have found that phototherapy with mixed blue±red light, probably by combining
antibacterial and anti-inflammatory action, is an effective means of treating acne vulgaris of mild to
moderate severity, with no significant short-term adverse effects.
