"I bought the full size after receiving a sample because it was that impressive with just a few uses. The full size has lasted over a year, and I used it nearly every day or two, but this oil does perform! I don't think anyone expects a full face lift, but what I have experienced is a very radiant skin complexion, the curiosity of watching a dark spot on my temple literally flake off, and fine lines around my eyes soften up nicely. I have recently ran out, after decanting the very last drop, and I'm definitely buying this again. Oh...and if you are into the scent of oils, this is fantastic!"
