Throughout its lifetime P. acnes bacterium produce porphyrins. The blue light will cause photo excitation of these P. acnes porphyrins. This will form singlet oxygen within the microorganism itself, leading to the selective destruction of bacteria. Shorter wavelengths (blue light – 420 nm) are capable of the greatest absorption that specifically target bacteria; whereas longer wavelengths (red light – 560 nm and 590 nm) produce deeper penetration into the skin, targeting inflammation. The heat soothes the acne lesions, initiating a natural healing process that causes the rebuilding of a new collagen in the skin with smoother texture and improved acne scars appearance.
Considering that P. acnes is rarely present without concomitant inflammation, the treatment combination of blue and red light plus the heat has demonstrated considerable success in treating mild to severe inflammatory acne.
During each treatment session clients may feel a slight tingling sensation.
Recommended initial course: 1 treatment every week for 6 weeks.
Destruction of P.acnes continues for a few weeks following the last BBL treatment and the effects of the treatment will be maintained until bacterial populations rebuild to their initial concentration.
Some clients may require maintenance treatments at 3 - 6 months intervals after the initial course of treatments.
BBL acne treatment can be performed not only on the face, but on the back, shoulders and chest as well.
Lori Haddad, D.O., a dermasurgeon in private practice in Birmingham, Mich., considers BBL “the Rolls Royce of pulsed light systems for superior results in less time.” Dr. Haddad treats acne with BBL, for which patients come in every two weeks for about six sessions. “We use a combination of blue light, yellow light and red light,” Dr. Haddad conveyed. “After three treatments, we notice about a 70% improvement in acne, and by six treatments there is a 90% or greater improvement.”
