Palm Oil (Elaeis guineensis) – A rich natural source of glycerin, a humectant which holds water to your skin. This quality makes palm oil an effective moisturizer, while forming a barrier to help retain your skin’s moisture. Glycerin also has a hydroscopic action, drawing water to your skin from the air. Glycerin helps to improve your skin’s natural elasticity and suppleness while also defending against dry skin conditions.  People have been using for palm oil for countless generations. Archeologists excavating an Egyptian tomb believe they discovered palm oil residue, which suggests the substance was in use in 3,000 BCE.
