100% vegetable glycerine, to be sure. I could not get ride of the crepiness under my eyes, and all around my eyes, seemed to lack the "spring back" if you gave the skin a slight pinch. My skin is normal/dry. I decided, out of desperation because none of the moisturizers I had were working, to pull out my vegetable glycerine and give that a try because it is an humectant. Sure enough, it completely eliminated the crepiness and gave my whole eye area the "spring back" or elasticity it was lacking. Glycerine leaves my skin dewy and moist - could not be without it!
