A few years back, I got a facial at a salon that used this machine. Hoping to replace expensuve IPL treatments, I looked this machine up. 1300+$. Yikes! I was so excited to find the cist down more than 1K$I've been using the device almist a week now. My facial acne ( and at 55 yrs old, aggh! Darn those pesky chin hairs) is healing nicely. The expected white bumps came up and passed. This is to be expected as collagen pushes out impurities). Already my skin has fewer visable pores. I have also been using the device on my wretched lower back and shoulder injurues. I have very high hopes of younger, acne free facial skin and pain relief from injuries with use over time!I’ve never thought to buy a LED machine before, until I happened to see this product when I was shopping for regular disposable face machine. Then this LED face machine suddenly attracted my attention, why not to buy a long term reusable and well functioning product instead? It seems spend more money at the time of purchase, however, you will save a lot overall. I remember when I go to the beauty store to do facial, I pay extra money for the LED facial option, and they only use the LED on my face for ten to fifteen minutes maybe, now I can do my LED facial at home by myself, easily and money saving!This is an amazing machine which has many different functions to treat problems of different skin types. Not only can it improve skin tone but it can also make skin tighten. It has 7 different colors which represent different functions. I like to use the red light color the most because this color can stimulate the production of collagen.More importantly, this light is suitable for all kinds of skin. As now I used blue light, it does improve my skin condition and my skin looks smooth and bright, I am not sure if it is maybe my psychology effective, but I am sure if I keep using it, it will have a big difference.The package came in shape and perfect condition. The led therapy does really takes its job seriously. It neither make your face feel burn nor irritated. Fits great (a little pressure around the eyes when laying down, but not too bad!I have received so many compliments on my,but in conclusion, I am happy with the purchase so far
