4. Skin Softener
One of the oldest uses of Vaseline is as an overnight salve. When Vaseline is applied liberally to the skin and then covered (so that it doesn’t get all over the sheets), it can help heal cracks, soften skin, improve dryness, and reduce calluses.
Many people use it during the dry winter months to protect their hands. It works wonders for people who must constantly wash their hands, such as chefs and medical professionals, by counteracting the drying effects of soaps.
