Yes, I tried both red and blue light therapy. In my opinion, red light has more benefits because it stimulates collagen and helps with the skin's overall health. Blue light is good too, but it might cause some superficial breakouts as it pulls out bacteria from the skin and unclogs pores. For me, blue light didn't do that much but blue & red together is a good combo. My acupuncturist used a portable red light and the first time it made a huge difference, and I was even wearing makeup when she did it. I recently got a facial with red and blue light, and the results are good but you have to keep up with it. Also, it works better when it is close to your face, or even touching your face (hopefully the spa sanitizes it after each use!), rather than what is shown in the picture you posted.
I'm a bit nervous about buying a home system or even a portable device, I would rather have an expert do it in case it malfunctions (I read some user reviews for various LED lights and some were saying that they got burnt or that their hyperpigmentation got worse).
I also tried a red, blue, and green light sauna for the whole body. It was an interesting experience, but I'm not sure if it did anything other than detoxing because I only use it when it's free.
Another thing that I find works as good as red light and better than blue light is high frequency.
