I wasn't a believer in essences until this popped up on my radar. As an esthetician, I love learning about new treatments and products from around the world. I was, however, under the impression that essences were just watered down serums...but then I found SK-II. I tried this under my moisturizer at night and woke up the next morning with smoother, more even skin! Definitely going to invest in a full bottle whenever I get the chance!
