I am a 38-year-old man with quite a lot of body hair, especially on my back, ass, stomach and chest.
I bought this device and have been using it myself for the last 8 months. Once a month, I shave my stomach, chest, bottom, armpits, arms and back, and then use the device on the highest level 2x after i shaved myself (once the day i shaved myself once the day after).
The flashes can be a little painful, but it is still okay and you get used to it. In the intimate area and on sensitive parts of the body, it hurts more - but it is still okay. The results are good, but not the same everywhere. On my back, the hair almost does not grow back anymore after 8 sessions. On my lower arms, the hair has become much finer. In the intimate area, under the arms and on the bottom, the hair is also thinner. Only on my stomach and chest, the result is not very strong yet. The hair there is thicker, so maybe it needs more time.
The device is a bit expensive, but before this I tried IPL and it did not work for me at all. This device is worth the money. I will continue using it and I hope the results will get even better the more I use it.
Overall, I am happy with the device and I can honestly recommend it.
