Petroleum jelly medical grade is a mixture of natural waxes and mineral oils that together lock moisture in skin, moisturizing it to repair and relieve dryness. 

Petroleum jelly medical grade is made by the waxy petroleum material that formed on oil rigs and distilling it.

Petroleum jelly medical grade has been used in various ointments and as a lubricant.
