I had never tried a liquid exfoliant before but what the heck, it was in the box and I'm so happy I gave it a chance. I just bought the full size because it's become part of my routine. I had enlarged pores on/around my nose, oily t-zone, tendency to have occasional acne, and uneven skin tone. Sometimes I would have dry, flaky areas too. Using this exfoliant has improved every single one of those problems without causing any sensitivity. It's had an almost "airbrushing" effect on my 39 year old skin. My skin is softer, clearer, less oily, more even-toned and my pores appear much smaller than before. Thank you Birchbox for introducing me to it!
