Our Blemish Fighting Blue Light destroys the bacteria which causes spots and helps in the prevention of breakouts. Exposure to blue light at 415nm interacts with the p.acnes bacteria creating a photodynamic reaction resulting in bacterial destruction! In addition it helps balance sebum production and improve skin clarity. Applied in combination with Red and Near Infrared light, a Dermalux treatment offers enhanced anti-blemish results and is excellent as a post treatment procedure to help minimise breakouts and reduce redness.
