I have PCOS, and spent tons on money on clinical laser, I took about 30 sessions over 3 years and never worked. I thought to give this a shot, hopeful of the reviews I saw. I started to use it every week for 4 months and saw the hair growing a little bit thinner and scarcer over these months. It didn't work on my bikini area. Actually, after these four months the device stoped working and they send me a replacement with no more questions asked, their customer service is incredible. However, after I stoped using it, my hair started growing back to the way it used to grow. It is a great product, and the service is incredible, even after not getting the results I hoped for, I do recommend it.
