Use it once a week for impressive results. Also, I have read the instructions carefully. Happy that, it can be used on legs and bikini line, as well as underarm. I am having sensitive skin, and it works gently on my skin. I was so excited when it arrived and I used it the first day and I am impressed by the result after a few weeks. It comes with professional packaging and detailed instructions. I highly recommend it to beginners and would suggest using it at level 3 for the first couple of times just to see how your skin reacts to it. Give it a try, the results can be impressive.
