1 Visible blue light kills acne bacteria. 2  Three blue light treatments kill about 99.99% of acne bacteria that the light reaches, although some acne bacteria live deep in pores. 3  Red light therapy can help shrink the sebaceous glands that produce the oil that clogs pores.cne bacteria are killed by visible blue light, that is, light you can see, not UV light, of wavelengths between 407 and 420 nanometers. The bacteria have pigments in their protective cell membranes that resonate at those frequencies. These pigments break down the membrane, eventually killing the bacterium.
