At first I was really skeptical about this product. I mean Skin Rev-er Upper? Really? At first I did not notice any immediate results from this product as far as the promise to improve my complexion. However, after a few weeks I noticed my skin had started looking brighter--more refreshed. The only product I had changed/ added to my routine was this. Before using this product my skin was not completely even and I suffered from a few breakouts. Although my slight hyper-pigmentation and minor breakouts had never been a major worry of mine because a little foundation or tinted moisturizer was all I needed to cover it up, I do not miss not having to cover them at all! Even though I cannot judge if it will produce miraculous results for anybody that suffers from extreme discolorations in their complexion, I will say that this product was able to help my skin and I love it. In addition to improving your complexion, the product claims to serve as a primer. I do not use primers frequently but I have noticed that the longevity of my foundation increases when I use this product. I am happy to say that I will be repurchasing this product!
