I received this as a sample, and it ended up being so effective and wonderful that I replaced my current eye serum! First of all, a tiny amount goes a very long way. The skin around my eyes didn't look so bad to begin with, but this serum seems to have brought it back to life. The very small wrinkles starting at the corners of my eyes are almost invisible, and the skin all around my eyes is smoother and brighter. I highly recommend using this under an eye cream if you can tolerate both. I give them a minute to sink in, and then I go ahead with eye makeup. I am eager to try other products from Kahina Giving Beauty now.
