Vaseline Hypoallergenic Newborn 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.
