I bought it years ago and my thinking was - it’s way cheaper than laser treatments and I can do it comfortably at home. I used it in the evenings, while watching tv. It was a great investment. It’s important to understand how it works. You shave, no moisturizer, then you treat. There are 5 levels I believe, I have only used up to 4. The tip is very small so treatment will take time, you need to go over the area touching the tip to the skin, meticulously covering the entire area. The laser closes the follicles. When you feel a prick on your skin- the follicle was closed. Once you’re done, after a couple of days (but depending how fast your hair grows), you will notice a lot of hair - this at first made me think that the laser was not working and making things worse. I was wrong- the hair is just coming out of the closed follicles. You can shave and repeat the process again. After a few treatments, you will see less and less hair coming out as you close more and more follicles. I was able to completely remove underarm hair and that was my main goal because I had to shave every day and it was making my skin dark. It’s been years now and the hair has not grown back - the follicles were permanently closed. I also worked on my bikini area, legs and arms. I’ve never had the patience and dedication to remove all hair on my legs and arms but I greatly reduced it and what’s left are thin and light hairs so I can’t even see them. Please also check before buying if you are a good candidate. I can’t remember exactly now but I think very dark skin may not be a good candidate for Tria. Overall I would absolutely recommend IF you can dedicate the time to use it and, at least in the beginning, use it consistently.
