Liquid Paraffin vs. Glycerin

Key Differences

Liquid Paraffin, a clear, odorless oil derived from petroleum, is primarily used in cosmetics and as a laxative. Glycerin, a colorless, viscous liquid from animal fats or vegetable oils, serves as a humectant in cosmetics, retaining moisture on the skin.
