P. acnes, the bacteria responsible for causing acne inflammation, pump out tiny molecules called porphyrins. When those porphyrin are exposed to certain wavelengths of light (Dr. Cocco Light in this case), they produce free radicals that kill the bacteria. Without P. acnes around to cause inflammation, acne clears up.
An Overview
Dr. Cocco Light Therapy is an FDA approved skin treatment that harnesses specific bands of the light spectrum in order to target and eliminate acne bacteria, accelerate wound healing and induce collagen production. For years, it was clear that direct sunlight could help diminish the signs of acne, but for obvious reasons, sustained exposure to the sun could also do as much damage as good. This is why scientists set to work on pinpointing which parts of the spectrum helped trigger the chemical reaction that was breaking down Propionibacterium acnes. They found that it was visible near violet light, rather than ultraviolet light, that was killing the bacteria. This meant that acne patients could be treated with high intensity, narrow-band Blue Light Therapy, without having to worry about the skin damage risks of UV light. Dr. Cocco Light Therapy can also treat skin conditions like dark circles under the eyes by increasing the elastin protein in skin.
