Mechanism of action

Petrolatum is a semi-solid hydrocarbon mixture that creates a hydrophobic occlusive layer on the skin. This barrier reduces transepidermal water loss (TEWL), maintains skin hydration, and protects the underlying skin from external irritants and pathogens. It is a non-medicated emollient used primarily for skin protection and moisturization.
