There are five different kinds of Acne:
1. Acne vulgaris: it is a clogging of the hair follicles that leads to unsightly, and sometime painful, skin lesions and pimples.
2. Acne conglobata: It usually affects males, it covers the back, chest, and buttocks with pustules and nodules, which often connect under the skin, which might cause a severe bacterial infection, as well as extensive scarring.
3. Acne cosmestica: It is triggered by topical make up. Characterized by small pink bumps.
4. Acne medicamentosa: Caused by sensitivity to drugs and medicines.
5. Acne rosasecea: It is rather an inflammation of the face, neck or chest.
Photo therapy, is most effective in types 1, 2 & 5, in those types a bacterial action is present especially P. acnes which tend to produce endrogenous porphyrins (mostly coproporphyrin III) as a part of its normal metabolism. High intensity broad spectrum light is absorbed in the photo excitation process and releases a sing-let oxygen, who proves to be fatal to the bacteria, and effectively clear inflammation in a fraction of time it takes for standard topical or oral treatments to do the same. This reaction is confined to the bacteria and has no effect on surrounding tissue.
The Acne starts when the opening of the hair follicle is blocked. The bacteria that leave inside the hair follicle (P. Acne) starts to multiply rapidly and the bodies immune system tries to fight the bacteria – starting an inflammation. And the Acne appears. As long as the bacterial activity continues the inflammation continues and the Acne flourish.
The intensive light releases an oxygenator that eliminates the bacteria, thus ending the inflammation and the Acne.
