Blue light (420nm wavelength) kills acne, red light is supposed to "boost overall cellular energy, increasing our body’s natural production of collagen and elastin and increasing microcirculation." Supposedly blue light and red light together kills acne even more effectively than blue light alone. So no, you do not "need" both blue and red, blue works for 90% of people, but blue and red both is supposed to work even better.

answer 4
Blue light kills acne forming bacteria. Red light increases the speed of your skin's healing process. Whether you need both probably depends on what you are prioritizing. The zap is a good place to start to see if light therapy works for you (it works for 90% of people). Now that I've used it and seen it work, I'm looking for a product with both forms of light.
