Please note: In my book, Rosacea 101, I wrote a chapter on Light Devices including IPL, Laser and LED which you can read this chapter in my book on page 67.
Low level, light emitting diode therapy has been reported to help rosacea in some of the anecdotal reports in internet rosacea groups. Some rosaceans even build home made devices while others receive therapy from well established cosmetic and dermatological treatment centers. Here is one report on such devices:
"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....
...Blue light (407-420 nm) and red light (633- 660 nm) are promoted for the treatment of acne. They work by exciting high amounts of intracellular porphyrins naturally generated by Propionibacterium acnes (P. acnes).....Blue light and blue-red combinations have demonstrated efficacy in mild to moderate inflammatory acne, having a physical modality comparable to treatment with topical clindamycin but inferior to benzoyl peroxide plus clindamycin....Red light (633 nm) may aid in effectively healing long-term torpid ulcers and may enhance angiogenesis in the rabbit ear chamber model...."
