I purchased the Flasher 2.0 in May 2022. I used it in my legs, bikini, underarms and upper lip twice. The 1st time I had no issues. The second time I notice about 30 mins after I had red welts on my legs. These eventually turned into darker scab like lines then white scars. I thought that my legs would prob even out over the summer and they would eventually disappear. I wanted to give more than enough time before I wrote a review to see what would happen. It’s now November, about 6 months later and the scars are still VERY much there! I have not used this since the second pass in May. I have had Tiger striped legs for 6 months now! Thank god this did not happen to my face!!!!!!! But I will def not give it the chance to mark up and more of my body. To be VERY clear, I followed all the instructions and only had this result on my legs. Why legs were very light at the beginning of May as it hadn’t been warm enough yet to wear shorts. I am not just letting my hair grow out to go back to waxing 😕
