Petrolatum is basically an emollient. Emollients help protect the skin from outside influences while limiting transepidermal water loss. This yields more complete hydration of the skin. Emollients close cracks and fissures by filling spaces around desquamating but attached skin flakes, sealing moisture into the skin through the production of an occlusive barrier. The net effect is softening of the skin. Emollients are commonly used and include mineral oils (like liquid paraffin, petrolatum), waxes ( like lanolin, beeswax, carnauba), long-chain esters, fatty acids, and mono-, di-, and triglycerides
For the best results, if you use petrolatum, pre-soak the area with warm water before applying.
