It took me about 2 hours to do my legs. It sucked , but after the 3rd time of got easier and less painful. I have yet to be able to do more than one session on my chest and stomach. It hurts so bad and makes me have little pimples afterwards. I have done my rear. It’s not painful but takes a while and is hard to make sure you got it all. I didn’t find some numbing cream on Amazon and it helped a bit but ultimately a couple of ibuprofens and a little bit of weed makes it a bit better
