I absolutely love this product. After years of using various high-end products with the prices to match, I cannot believe the price and quality of Evolve products. From the first time I used the serum it absorbed so easily, I did not get any negative reaction on my skin which usually happens when I change to a new product. My skin, just after a few days had a clarity and glow that my people noticed. As a guy, it's surprising to have my female colleagues say how fantastic my skin looks and asking what I was using. Since my first use of this serum I have bought a number of other items from Evolve, I'm a total convert.
