Glycerin can be applied directly to the skin and acts as a very effective moisturizer on the skin. It helps hydrate your skin by absorbing water from air reducing the dry and dull patches on your skin, as well as filling the cracks in dryer skin. It’s therefore very useful in winters as well. It adds hydration and health to your skin, while creating a layer that is critically needed to work as a natural barrier to protect your skin from pollutants and skin disease causing bacteria.
