I had major reservations before buying this product. Most concerning of all was how my sensitive skin/keratosis pilaris and would react. But, as a hairy human, I was tired of the irritation/redness from every other hair removing process (shaving, waxing, epilating). By the time my skin calmed down, the hair was growing back. So, when quarantine hit, I took the plunge and bought this handset. And WOW am I impressed. I did my legs, arms, and underarms. I shaved before bed and used the device the next morning to not irritate my skin. During the first 3 weeks, I noticed my hair development SIGNIFICANTLY slow down. And I was only using it at a level 3 out of 5. The real results happened during weeks 4 through 8. I was able to move up to a level 4 all around. Many areas were no longer growing hair and the spots that were had thin and slow-growing hair. Weeks 9-12 mainly cleaned up the areas that still had hair. Am I completely hairless? No, and I didn’t expect to be. But the hair that I do have is not very visible at all. It’s crazy what a difference hair can make in our lives, but I feel a lot more confident in my skin and that feeling is amazing.
