In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

Great product but not great moisturizer
I used this product for a month. It has done great job for my acne prone skin and caused no break outs. However, it is not a great moisturizer itself. I mostly used it before my actuall moisturizer. Plus, it has spf.
