    Vitamin C

    I was such a skeptic of the vitamin C serum. I doubted all the reviews. Boy, was I ever wrong. I LOVE the Vitamin C serum! I regret that I waited so long to try this product. I immediately saw a noticeable difference in my skin. Yes, my skin had a glow and the skin felt so soft. It smooths and it improved the texture and appearance of my skin. I apply every morning to my face and neck with the leftover in the palm of my hand I applied to the top of my hands. I am constantly rubbing the top of my hands because they are the softest and smoothest I have ever felt. On my next order I will subscribe to this product because I never want to be without it. This product is everything they say it is and more.

    High quality serum

    Love this vitamin c serum for many reasons. The main reasons are the consistency and the pleasant smell of it compared to other serums I have tried. I also love the color of the bottle and the was the product dispenses from the dropper.
