Blue light therapy is one of the most popular treatments for acne. It works by destroying acne-causing bacteria from deep within your pores and oil glands to prevent breakouts.
The bacteria responsible for causing acne, the p.Acnes bacteria, contains a naturally occurring compound called porphyrins. Blue lights targets the porphyrins, breaking them down and killing them, banishing breakouts and inflammation.
It’s been clinically proven that blue light at a wavelength of 415nm can target this bacteria underneath the skin to eliminate the bacteria that causes spots.
