Laser Irradiation
Lasers work by using various “soft pulsing light” wavelengths and intensities to help “reshape” scar tissue, making raised scars go down, and reducing the redness of the skin around healed acne postules.
The acne lasers actually emit a low, constant frequency of red light which helps to stimulate collagen, making scarring less visible, and helping to stimulate the healing of existing acne, and speed the whole recovery process.
Konftec utilizes patented, proprietary technology to deliver coherent blue and red visible light that efficiently activates porphyrins within the P. acnes bacteria.
When used in a series of brief exposure sessions, it provides a simple, non-invasive treatment regimen.

Phototherapy with blue (415 nm) and red (660nm) light in the treatment of acne vulgaris

Papageorgiou P, Katsambas A, Chu A.

Unit of Dermatology, Imperial College of Science, Technology and Medicine, Hammersmith Hospital, DuCane Road, London W12 0NN, U.K.

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 660nm) 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.
