I did a lot of research on this product before I decided to purchase it. I read many reviews and I could not really find any negative reviews. What I did find was reviews saying within a week, they saw a difference. I have had large to mid size pores for years and have never found a product that minimized them. Within 2 weeks, my pores were 50% smaller!! I could not deny the difference. My mother noticed a difference in my skin right away when I saw her after using the product for a month. Right now I am on my second bottle and I am at 85% improvement. The tone, texture of my skin has changed. This product is amazing. I saw my dermo today and he took notes on what I was using as patients always ask him about minimizing pore size. I also use the Bioglycolic Lotion and have not had one acne cyst since. It really keeps the skin clear and almost polished looking. I am trying the under eye for dark circles now but jury is still out as I am not even done with first jar.
