Description and Uses

petrolatum (petroleum jelly; Vaseline) softens and smoothes the skin. It forms a film on the skin’s surface, preventing moisture loss caused by evaporation, and protecting against irritation. Its disadvantage lies in the difficulty of effectively and properly removing it from the skin. Studies indicate that petrolatum accelerates the recovery of skin surface lipids, permeating throughout the stratum corneum layer, and allowing normal barrier recovery despite its occlusive properties. Thus it does not form or act as an impermeable membrane. It is a purified mixture of semisolid hydrocarbons from petroleum. Petrolatum imparts a greasier feeling than other emollients and also has the potential for clogging pores and causing comedogenicity. Although it can cause allergic skin rashes, petrolatum is non-toxic to the skin when properly purified and of high grade.
