Vaseline
Vaseline was founded by Robert Chesebrough in 1870, making petroleum jelly one of the oldest branded skincare products in continuous production worldwide. The product is triple-purified using Chesebrough's original process, is FDA-registered as an OTC skin protectant, and carries the National Eczema Association Seal of Acceptance. Over 150 years of clinical and consumer use have established it as the gold standard occlusive in dermatology.
