For the past 2 years, I've had an issue with lines around my eyes. There were 2 particular wrinkles on each eye that were deep enough to cause my foundation to accumulate in them, making my overall makeup look flawed. I had to constantly wipe makeup off my lower lids. So frustrating. I began using the serum in hopes it would at least lessen the appearance. It did after a few weeks, and now there is no more wiping makeup from the lines! I am in my early 30's, and I want to maintain a youthful appearance before the lines become permanent. It is so cool and light on my skin as well. The bottle is small enough where I thought I was not getting enough for my money, but I was wrong. I have the results I want, and am still on my first bottle since it takes so little to do the job. I am very satisfied, and recommend it to those with reservations.
