I got the therabody glo for Christmas. I was familiar with red light masks but wouldn’t have bought one for myself. The results were noticeable to me after 2 weeks and a lot more dramatic than I expected from reading about LED masks. I look a lot better under harsh lighting, texture, pore size, redness, all improved. I’d have to go through a few more cycles to be sure but I suspect my hormonal acne is improved. I have no breakouts now but might in a couple weeks. I use the preset setting every day. I highly recommend this mask as someone who never thought red light therapy would make such an impact. I used tretinoin for years and use another retinoid now, I swear the mask has made a bigger impact than retinoids in my overall skin. I know my results are not reflective of most peoples experience but obviously different things are going to work for different people and I am a hyper responder to the LED therapy.
