UPDATED REVIEW:It's been six months of use, and the hair buffer is still going strong. I used to have "chicken skin" and it was such a complex that I always wore shirts with sleeves. The bumps haven't completely disappeared, but they're mainly only apparent to me, who clearly is more critical of my skin than anyone else would be. I loved how silky it made my skin feel, but now I have people commenting on how smooth my skin looks. The skin exfoliation you get in addition to hair removal is probably the best benefit. I've started to buy these for random small gift needs. They're definitely going to be stocking stuffers this year. The only thing I would say to ensure the best performance is to clean the buffer every time you use it.ORIGINAL REVIEW:As I aged, the hair on my arms and legs have gotten finer and finer, up to the point that no one notices if I haven't shaved for months (except for my husband lol). I also have keratosis pilaris, which tends to cause ingrown hairs from my weak hair follicles. I've tried various creams and treatments, and this hair remover seems to be the best solution for me so far.So I've tried other buff away hair removers, and they end up just abrading my skin and leaving the hairs in tact, because they're so fine. This one actually works, and with less force and effort than the other sandpaper type buff removers. Don't get me wrong, if you overbuff, you WILL hurt. It's like the worst razer burn you've had in your life.I've had the best results with moving the buffer in fairly large circular motions or just moving vertically, then horizontally across the surface. You don't need to apply much pressure at all. I'd do minimal buffing the first time to see if it causes any pain, then progressively do more later. The first patch I tested felt fine when I was doing it, but 10min later, it turned red and burned when I applied lotion. Instructions say to use creams or lotions beforehand for sensitive skin. I did that for the small hairs on my upper lip, and it worked perfectly. My skin is super smooth and the baby hairs are gone. I've tried using it in the shower with various soaps, and I feel like this causes too much friction, which can cause excessive abrasion.I'd definitely recommend this product, but test in small patches and work progressively with very little pressure. Longer strokes worked best for me, but it my be different for others. It'll take time and patience to find the optimal amount of pressure and number of passes, but when you find it, it'll be well worth the effort. I'm so happy I can stop buying expensive shaving creams/gels.
