Cerave Cerave Moisturizing Lotion, 12 oz by CeraVe

Does any adults use this instead of regular moisturizing lotion since this version doesn't have paraben? Is there other difference?

Manufacturer, please list which ingredients in this product are made out of animals, e.g. cholesterol? others?

Can I add a few drops of essential oil to this moisturizer?

Where can I order more cars to go with it?
