LED light therapy is a painless, relaxing, non-invasive skin-care treatment that has multiple benefits—particularly stimulating collagen and treating mild to moderate acne. It works by using an array of bright light-emitting diodes (originally developed by NASA!) that send low-level light energy into the deeper layers of the skin.
Red LED stimulates cellular activity, including the fibroblasts that produce collagen, which gives young skin its plump look and the Blue LED works by killing propionibacterium acnes, the bacteria that lives below the surface of the skin and is responsible for acne.
Both are highly effective when part of a series—usually six treatments one to two weeks apart, followed by a maintenance treatment every month or two. LED treatments last about ten to twenty minutes, and can be a stand-alone treatment or part of a facial.
