Most Petroleum Jelly today is used as an ingredient in skin lotions and cosmetics, providing various types of skin care and protection by minimizing friction or reducing moisture loss, or by functioning as a grooming aid. This Petroleum Jelly may be particularly good for regular, less dramatic skin injuries. Make sure that the surface you apply petroleum jelly on is properly cleaned and disinfected. Otherwise, bacteria and other pathogens can get trapped inside and delay the healing process. Petroleum Jelly’s benefits come from its main ingredient petroleum, which helps seal your skin with a water-protective barrier. This helps your skin heal and retain moisture.
