Actually, I have to rectify my previous answer. As someone pointed out this device is not advertised as a "permanent hair removal", and obviously it doesn't have the results of one (which explains my disappointment with it). It's just a new technology epilator. To understand better, the quick reference guide says: " For best results, use Me on the same area once a week for 7 weeks. Performing additional monthly treatments, after completing the first 7 treatments, will help you maintain your smooth, silky, hair-free results". Maintaing is one thing and permanent removal another thing.
Yes, it' s a permanent hair removal device and it can be used on the bikini area. In fact it can be used on all areas except the face. As for permanently removing the hair, yes, it is supposed to do so, but be aware that hair growth is also connected to hormonal activity and through out our life our body keeps changing; therefore, no device will guarantee you will be totally hairless for the rest of your life. You may need to repeat the procedure whenever is necessary. Personally, ME Smooth didn't work out for me at all, but maybe it works for others.
