In the dark about amber LED light therapy
Finding answers to these questions has so far proved to be illusive. I certainly didn’t come across any research specifically on amber LED (although there is plenty on red and blue light). Neither could I find much persuasive evidence as to why amber differs from red.
The clearest description of amber light is given by ProLight LED, which sells a device for $379, claiming that it is for redness, facial capillaries, rosacea, flushing. Other manufacturers seem to combine it with red light for general anti-aging: Osmosis Professional or the LightStim $349.
I’d love to know more about amber LED, so if anyone has insights I would love to hear them. In the meantime, here’s some further reading on red LED and how it works to boost collagen and the production of ATP (the energy engine of cells). And here there is more on the research on acne and blue LED light.
