The principle of red and blue light treatment for acne

Red and blue light treatment for acne uses blue light with a wavelength of 415nm to act on the surface of the skin, inducing apoptosis of Propionibacterium acnes and playing a bactericidal role. In addition, it can also effectively inhibit the secretion of sebaceous glands. The red light will penetrate the surface of the skin, act on the scar tissue, stimulate the cells to secrete collagen and fibrous tissue, thereby removing acne marks, repairing acne scars, and restoring the skin to a translucent and elastic appearance.

Most red, blue and yellow light devices use light-emitting diodes (LEDs) or xenon lamps as light sources, so red, blue and yellow light is often referred to as LED light.
