Petrolatum (petroleum jelly; Vaseline) — very comedogenic! AVOID if prone to acne! Otherwise, softens and smooths 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.
