These are two of my favorite, super lightweight, but potent serums. I use the Vita-C almost daily and the MGF several times weekly.
Tip for Baby Soft Hands - Keep the MGF next to your sink and after you wash your hands, add a couple of drops to the back of your hands. In a day or two, they will feel like baby skin (and as long do this, they will stay that way). It's one of the best things that has helped overly dry/overly washed hands!
