Acne is a skin infection caused by the bacterium Propionibacterium acnes. Gram positive bacilli, which is anaerobic and purple, acts on the sebaceous follicle which when mixed with excess oil releases cytokines, the molecules responsible for inflammation. Using intense pulsed light to treat acne is based on heating the porphyrins produced by the bacteria “Propionibacterium acnes” causing its destruction. Exposure of the porphyrin (chromophore) to the light activates its excited state, resulting in the formation of singlet oxygen, a condition in which the oxygen atom is very reactive in contrast to its ground state which is a triplet state. Singlet oxygen combines with cell membranes to destroy bacteria. The photo-thermal effect also allows for the aseptic treatment of the area. Light filtration between 420 - 1200nm corresponds to an optical penetration depth between 0.5mm and 2mm in order to act intensively on the sebaceous glands that lie on the surface. It filters out all wavelengths except the blue light. In addition, pulsed light works on acne scars by stimulating the production of collagen and elastin by the fibroblasts.

According to our clinical study conducted by the Group for Research and Evaluation in Dermatology and Cosmetology (GREDECO) on volunteers recruited from the Hospital Pitié-Salpêtrière in Paris, the subjects who completed treatment of acne have been satisfied with the results.

Intense pulsed light is generally indicated for retentional or inflammatory acne of either medium or minor severity. It is used as a substitute to long term antibiotics as drugs such as isotretinoin which are already banned in several countries. Medical treatment of acne using pulsed light is a real medical benefit to patients.
