One of the most promising looking articles about the possibilities of the promising field of Light Emitting Diode Theray. The article mentions the Omnilux, Delphia del SOL, Max7, Medilite, Gentlewaves, LumiPhase-R, Revitalight, Soli-Tone, BLU-U and ClearLight.

Introduction: Several lamps that generate visible light, many of them using light-emitting diodes (LEDs), have recently found their way to the dermatologic armamentarium. Claims of their value in the treatment of a variety of conditions ranging from cosmetic (antiwrinkle) to acne, rosacea, and skin cancer are made to market them. The literature promoting these claims is limited and often questionable, however, dermatologists who own these units often report demand for their use, high customer satisfaction, and a sense that they deliver on their promises, despite a lack of clinical evidence from properly controlled studies. This article reviews promotional as well as relevant scientific literature (indexed on Medline) regarding LED-based devices and other units that deliver visible light at sub-intense fluences. Both types of literature were evaluated for their scientific validity of content. Photodynamic therapy used with exogenous photosensitizers such as aminolevulinic acid is beyond the scope of this review.
Conclusions: The level of evidence for the use of sub-intense fluences of visible light in dermatology is weak. As few randomized controlled trials have assessed the safety and efficacy of these devices, the dermatologist is left to infer the worthiness of incorporating LED-based technology from in vitro observations, anecdotal evidence, and commentaries appearing in trade (mostly non-peer-reviewed) publications.
The uncontrolled proliferation of services based on these devices at cosmetic/aesthetic locales where the personnel have little if any knowledge of dermatology and photobiology may be dangerous. Regulations that apply in many states to the use of lasers and intense pulsated light sources should be expanded to include these devices as the benefits (and risks) of their use in acne, rosacea, wound healing, aging, etc. (mostly medical diagnoses) relate to altering the structure and function of the skin, which constitutes the practice of medicine.
