Acne And Lasers. Bacteria That Produces Inflammation Connected To Acne Is Known As Propionobacterium Acnes.
Chronic inflammatory disease acne affects the sebaceous hair follicles. Multiple sebaceous glands and a tiny hair occupy each follicle. In a perfect world the sebum slides up the hair and out on the surface of the skin. When sebum becomes trapped in he follicle the skin bacteria multiplies in the clogged pores creating acne. There are areas of the body that are more susceptible to acne because of the number of sebaceous glands; they are the upper arms, scalp, neck, chest, back, shoulders and of course the face. While onset of acne can begin in the twenties or thirties it is fairly normal for it to start with adolescence.
The bacteria that produces the inflammation connected to acne is known as Propionobacterium Acnes or P. Acnes and one treatment is to aim at that bacteria. A naturally occurring molecule in the body known as porphyrins are released by P. acnes. Free radical damage that destroys bacteria; this happens when wavelengths of light are absorbed by the porphyrins.
Light that is in the blue wavelength range of 400 nm to 430 nm is best absorbed by the porphyrins. The treatment of mild to moderate inflammatory acne has been studied using a low intensity blue light source of 405 nm to 420 nm. 80% of patients experienced a 60% acne reduction after a study conducted for four weeks; each patient had 2 fifteen minute exposures. A 3 to 8 month acne remission was experienced. Damaging the sebaceous glands by a thermal or heat effect was another method proven effective by laser technology. After a six-month analysis of a recent study sixteen of seventeen patients experienced 100% clearing. This was a direct result of a 1450 nm diode laser that did 4 treatments 1 month apart. Right after the treatments biopsies were done and showed a lesser amount of oil as a result of the heat altering the sebaceous glands.
One dermatologist explained that lasers being used for scarring are not new, but using them to control acne that exists is a breakthrough. This treatment is not yet available and still being investigated. Insurance does not cover it and it’s not available to all patients.
Who can and cannot do laser/light source? Many states have not yet determined that. It is strongly recommended that they be only conducted by a doctor or under the doctor’s supervision. Don’t hesitate to ask your physician who will conduct the procedure and confirm that he or she is qualified.
