For those with severe acne problems, there are limited treatments. Some dermatologists prescribe certain acne drugs or acne facial soaps or other external treatments. But many dermatologists have taken to using blue light or red light therapies to treat acne.
Besides these two types of light, sunlight is the best acne treatment; but the UVA and UVB rays in sunlight are extremely damaging to the skin, especially during prolonged exposure. Since artificial UV didn’t work as well as real sunlight, blue and red visible rays were found to be effective and safer. These two lights actually have the ability to destroy the bacteria that cause acne in the skin.

The prescribed therapy is generally 3 days of exposure; this can get rid of almost all (99.9%) of the bacteria in the skin. The only real precaution dermatologists need to take with this treatment is appropriate eye protection.
