What the HECK is a LED Light Therapy Facial?
The variation of these light therapy treatments depends on the wavelength/frequency of the light, heat and penetration of the skin. To better explain the use of light therapy, think of a rainbow. When a rainbow appears we are seeing all the visible wavelengths and frequencies of light. The full spectrum of light is what you see during the day. It's appears as a daylight. We isolated different colors of the rainbow to produce different results in the skin.
