This is the second bottle of serum I have purchased. I saw positive results within a week of using this stuff. I have consumed beets and tried to get my nitric oxide through my diet but OMG this stuff is a miracle for my face. I am 52 and spend a lot of time in the Colorado sunshine. My skin is clearer, softer and noticeable less wrinkles. I can’t wait to see what continued use does! Try it ??.I have used this product & love it. In fact, I have found great results in my neck & forehead for sure. Overall my skin is brighter & healthier. I feel & look younger. I love this stuff.I have been using this product for a month and I can see the difference now, my skin is more smoothly and the small Brown spot almost disappear and so happy about it, I will continue to use it, and definitely, I recommend ?I’ve only been using this product for about a week but Im amazed that a stubborn white head near my nostril that has plagued me for years has now disappeared. If that is any indication of the effectiveness of this product, I can’t wait to see the results continued usage will bring!I attended a conference in Florida where I got to listen to Dr. Nathan Bryan and hear all the wonderful benefits of this product. I have been using this product for only 2 weeks. So far I have noticed a reduction in my fine lines on my forehead and around my eyes. I am very hopeful with this product.I use some really expensive skin products, and have been getting peri-oral dermatitis anyway. N1o1 started to clear up the red patches right away. My skin looks and feels so much better after only a few uses. I can tell it allows my other creams to better penetrate my skin and look better even under makeup.Actually works and makes your skin look better and tightens pores.I'll tell you what. This absolutely WORKS. My whole face looks different, better, younger. This will be my go-to from now on, despite how expensive it is. But you can get it cheaper, look up a site called Senergy. About $40 cheaper than this. The product is hard to get because it's made in Australia and they don't seem to have much distribution over here.
