Also known as: Petroleum Jelly, Vaseline, White Petrolatum
Petrolatum (petroleum jelly) is one of the most effective occlusives available, reducing transepidermal water loss by up to 99%. Despite its mineral oil origin, it is non-comedogenic and hypoallergenic when refined to cosmetic grade. It is the gold standard for wound healing and skin barrier repair. Dermatologists frequently recommend it for compromised skin conditions.
Comedogenicity ratings are based on the rabbit ear assay model. Individual skin responses vary. See our article on comedogenicity ratings for context.
