"I'm always rotating through different high-end products -- Roche Posay, Kinerase, PH Advantage, SkinMedica -- and I love something about bits and pieces within each brand. I'm 34 with fair, acne prone, sensitive skin. I've been using this product for two weeks now and it is one of the best things ever. Despite late nights plus a drive across the country, my skin is clear and glowing. I was a daily benzoyl peroxide user for my acne -- I thought I'd give it a try and go without and see if the oxygen promises were true -- yes, they seem to be! The sensitive areas of my face (around my mouth, mostly) peeled a bit during the first week, but it was nothing awful. I'm also using this product with Retin-A (0.1%) and they seem to work together beautifully. How could I not write a review!!!"
