Vaseline is a triple-filtered substance, which ensures it is free from impurities and safe to use. While Vaseline is the name, the product is actually petroleum-jelly based product. In the past several years, we’ve seen Vaseline, or petroleum-jelly, make its way to skin creams, soaps, cleansers, deodorants, lotions, and many more skin and hair products. There are so many ways you can use Vaseline. For example, mothers use it to prevent diaper rash. You can also use it to protect yourself from minor cuts and burns and to soften your skin.
