LED treatments work by using an array of bright light-emitting diodes that send low-level light energy into the deeper layers of the skin. Red light LED stimulates cellular activity, including the fibroblasts that produce collagen, which gives young skin its plump look. That helps minimize fine lines and wrinkles, treat sun-damage and stretch marks. Yellow light addresses skin problems, helps rejuvenate the skin, hastens wound healing, improves blood circulation to the skin tissues, and reduces signs of aging, like fine lines and wrinkles. Blue light LED works by killing the bacteria that lives below the surface of the skin and is responsible for acne.
These wavelengths are highly effective when part of a series—usually six to ten treatments, spread over 3-6 weeks followed by a maintenance treatment every month or two.
