Petroleum Jelly provides you with relief of dry skin and offers soothing protection for any minor burns. This versatile jelly can be used for a variety of things such as protecting skin from wind burn and chapping. The jelly works by acting as a form of sealant by becoming a barrier to the natural water loss of skin. It then builds up skin-softening moisture from inside the skin. Ideal for preventing diaper rash, petroleum jelly also comforts babies and toddlers from existing diaper rash.
