BLUE LIGHT THERPAY
Blue light therapy is a noninvasive treatment for acne that uses light to kill certain bacteria on the skin. Blue light is a part of visible light. It has a very important role in how our body adapts to light and dark cycles. Our modern lifestyle has increased our exposure to blue light. Not all colors of light have the same effect. Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night and can disturb sleep. The proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown.* Despite these negative effects, the appropriate use of blue light has several therapeutic benefits.
