What is blue light?
Blue light is a kind of visible light, and dermatology uses blue light mainly for inflammatory skin diseases, especially acne, with a wavelength of about 470nm. Blue light has the effect of rapidly inhibiting inflammation in the formation of acne, and for inflammatory acne, it is mainly the parasitization and reproduction of Propionibacterium acnes. Blue light can efficiently destroy Propionibacterium acnes without any damage to skin tissues, minimizing the formation of acne and promoting the healing of inflammatory acne in a short period, allowing inflammatory papules to be significantly reduced.
Blue light eliminates acne through a series of natural physical processes, including the elimination of Propionibacterium acnes, changing the pH level inside the cells, and also improving the immune mechanism of the muscle. Therefore, because of these mechanisms of action, the effect of blue light during the treatment process is very obvious. There is no discomfort during the whole treatment process, and the effect will continue after the treatment is stopped. Independently treating acne with blue light can reduce inflammatory lesions by more than 50%. When combined with red light, the treatment can better clear inflammation and post-acne hyperpigmentation. Blue light mainly plays a role in sterilization and immune regulation, while red light, in addition to being anti-inflammatory, can reduce acne marks and the possibility of post-acne scar formation.
