Vaseline Hypoallergenic Baby Healing Petroleum Jelly, A baby's skin is very sensitive, so the discomfort of diaper rash is never pleasant for either of you. A daily application of Vaseline Petroleum Jelly Baby keeps your baby's skin soft and smooth and adds a protective barrier that helps prevent friction between the diaper and your baby's skin. And that can help prevent diaper rash before it even occurs. Like the original Vaseline Jelly formulated back in 1870, our Vaseline Petroleum Jelly Baby is triple-purified to remove any impurities that could irritate your child's skin and heals dry skin without leaving behind a greasy residue. This protective Vaseline Jelly locks in moisture to help the skin's natural moisture barrier recover from daily exposure to environmental triggers that break down the natural barrier, like diapers, for instance.
