Petroleum Jelly is a mixture of mineral oils, paraffin and microcrystalline waxes that, when blended together, create something remarkable - a smooth jelly that has a melting point just above body temperature. The result - it literally melts into skin, flowing into the spaces between cells and the gaps in our lipid barrier. Once there, it re-solidifies, locking itself in place.

Petroleum Jelly serves two functions:

-Protects skin from the effects of weather and exposure

-Forms an occlusive barrier to the natural water loss of skin. So skin that is dry and chapped is protected from drying elements, enabling skin-softening moisture to build up naturally from inside the skin itself
