I did NOT get this product for a discount so my review is my honest experience with this serum. It leaves my skin smooth, firm and poreless and as soft as silk. I use it by itself after my rose water and can skip a moisturizer. It is not sticky or greasy and my Tarte BB cream just floats over it flawlessly. I had taken some hair vitamins that had made me get a red rash of a breakout and after a week of applying this amazing serum, the breakout is gone and the redness has almost disappeared. I had another C-serum but when reading the ingredients found out the top one was water which means the serum was mostly water. This serum has aloe vera and hyaluronic acid and vitamin c as the first three ingredients. It really works and fast, too. I ordered another bottle right away and will continue to use this day and night. Please don't change the formula or stop making this as I have very oily skin and can't stand most serum and moisturizers, but this is very comfortable on my skin. Love it!
