Review (4/5): you will see results if you commit to it
I've been using this for 3 months now and I do think this works with longterm use. You obviously aren't going to see overnight results but if you keep at it you will notice a difference on your wrinkles. Luckily I don't have too many yet but I did use it on the little areas where I'm starting to see wrinkles. I noticed a tightening of the areas I used the laser on for the past 3 months. I really liked the hyaluronic acid serum that was included in the set - the serum felt gentle and has no smell (fragrance free). On some days where I didn't use the laser I would still use the serum to moisturize my face. I looked into purchasing just the serum, which they do have for sale, as I really like the product. The laser is easy to operate and charge (usb). I didn't use this daily as I wanted to give my skin a rest, but I think if you used this religiously then you would see results at a much faster rate. It isn't painful, but you feel a little zap. I would equate it to the same level of "pain" as a derma roller, that spikey/zappy feeling - not painful, not super uncomfortable. That of course, will depend on your skin sensitivity. I recommend using the lowest setting first then working your way up as your skin sensitivity will allow. Don't force your skin into what it cannot handle - listen to your body's reaction!
I've seen so many of these laser type products for the skin/body, and never tried it because I didn't trust it. Nira is the first at home laser product that I decided to give a chance to, as I trust it. Overall I am not disappointed but do know that you need to commit to it if you want to see results. If you are going to use it once every few weeks then it will be a while before you see results, if ever. I plan to keep using this to stimulate my skin.
