Blue light kills acne bacteria. How? When blue light strikes acne bacteria cells it sets off a chemical reaction that causes the bacteria to self-destruct. No harm is done to any other cells on or in the skin. Here is a more scientific explanation from the AAD: "[Blue] Light gets at the core of what causes acne eruptions: P. acnes, the bacterial responsible for causing acne inflammation, pumps out tiny molecules called porphyrins. When those porphyrin are exposed to certain wavelengths of light, they produce free radicals that kill the bacteria. Without P. acnes around to cause inflammation, acne clears up." American Academy of Dermatology 2002Blue light acne treatment
The P. Acnes bacteria excretes a waste product. When blue LED light is introduced into the pore, it activates this waste product to release free radicals, which turn and kill the bacteria. Red light has a therapeutic effect on the acne. The speed at which the skin heals is greatly increased when it is exposed to visible red light. Red LED light uses non-thermal, low-energy light to increase blood and oxygen flow, which stimulates the skin natural healing process, and reduces the pain associated with acne.
Blue light acne treatment uses blue light (405nm-470nm) to kill acne bacteria on and under the skin instead of topical or oral medications. Throughout the treatment, the skin is exposed to a blue light source for a short period of time ranging from only a few seconds up to 15 minutes depending on the product. In-home treatments are recommended daily until acne is either cleared or under control, then the frequency is reduced to maintenance treatments twice to three times per week. Blue light is an effective acne treatment, but it's not a cure, so consistent treatments will be necessary to keep acne under control.
Give LED therapy for 15 minutes a day help you to be rid of Acne. The treatment procedure consists of a combination of red and blue light. The blue light kills the bacterium and the red light has a healing property. Treatment:- It is suggested that you treat yourself for 15 minutes every day or alternate days.
