LED (light emitting diode) light therapy was originally developed to fast-track the healing of wounds and post-surgery scars. The rejuvenation of healthy skin, too, was a happy coincidence. The complexion is plumped up with new collagen (which pushes the folds of the wrinkles out) and new elastin (which helps to tighten the skin and give it more elasticity). In-salon treatments are recommended 2 to 3 times a week for a course of 4 to 6 weeks
