I have used this product for 3 weeks. I found the smell quite overpowering and when applying the gel to my spots it stung. I found it abrasive and pulled my skin tight over the applied area. However within a few days I noticed a marked difference, my spots were disappearing in most places. I did find however that the product seemed to bring impurities out to the surface, so found I had the odd white head popping up, which was a good thing...better out than in I say! Overall I would recommend this product, as it did seem to help my skin look a lot better than before. The only downside is that Clinique products are pricey and so I as a single Mom would not be able to buy their products very often.
