After about a month of use, less density and intensity of hair growth is visible. Before using it, I shaved my legs one day and the next I was already scratching lightly, after a month of using this IPL, this scratching will start after about a week. I can do the face, armpits, stomach, entire legs including private parts within 20 minutes. Before this IPL from Braun, I had IPL 3 from TrueLife, where the same thing took me 90-110 minutes. And that really irritated me, that' s why I decided to buy Braun Smart IPL Skin I·Expert PL7253 and I' m really connected and it' s really worth the money, especially in terms of saving time and you don' t have to be extremely consistent and if you leave a few millimeters behind at intervals, this IPL can easily handle the intensity of the flash. It happened to me a few times that it indicated the wrong location or lit up red, it was enough to switch to another location for a few seconds and after the white light to return to the original location, it worked again. However, what annoys me extremely is the mobile application itself, which, in addition to being unintuitive to use, during the first setup did not want me to include the first day of IPL use in the plan, but I had to set the following date for further use. Furthermore, each part must be planned extremely individually, the density and color of the hairs are indicated. Then, when the plan is played, each party has its own questionnaire and you always have to go back to the beginning to be able to fill out the questionnaire for each party in the plan. Also, there is a bad flash remaining counter. For 14 days even when I used it it showed me the same number of flashes left. So the mobile application itself really didn' t work out, compared to the IPL device where you see the effects, of course not immediately after the first day, and it takes time, but in the long run it' s great both in terms of the result and the speed with which you " flash" your body . Personally, I missed the function of automatic flashes, mainly for hard-to-reach places and for more pleasant usability, it would be more pleasant than holding the button or pressing it. It is nice that the device also comes with a bag and different sizes of heads, and a razor blade. I also travel with IPL, so it' s nice to have everything together. Just add a mini shaving gel and it' s perfect for traveling. During use, it did not happen to me, against competing cheaper devices, that it overheated and I had to wait for it to cool down, I could use it comfortably for 20 minutes even when it was 35°C outside. It can be operated with one hand, including changing the heads.
