This is my absolute favorite facial product (and I use a lot!) While technically not a moisturizer, it works so well that you`ll never need one again! It works by causing your skin to maintain the water it needs. I have had flaky skin since I turned 30 (I`m 37 now), and have tried tons of different moisturizers. After a week of using this product, my skin looked wondefully hydrated. With continued use, it also helps to ``plump up`` fine lines. It works great on lips too. It is a clear gel, goes on easily, and does not feel greasy. Within seconds it is absorbed by your skin and you cannot tell that you have any product on it. It is a great primer for make-up -- making your skin incredibly smooth. It looks like a small bottle (and it is), but it only takes about 4 drops to cover your entire face. I cannot say enough good things about this product.
