Our take
Is Liquid Paraffin a Good Ingredient?
Liquid paraffin earns Great on the strength of its occlusive performance: decades of use, high stability, and a low likelihood of irritation or sensitization when it's cosmetic-grade and properly refined. It consistently reduces transepidermal water loss and supports barrier comfort, a hard combination to beat.

Frequently found in ointments, barrier creams, intensive moisturizers, and lip treatments.
Before you use it
Safety
Generally well tolerated and considered low-irritation for topical use. Very occlusive textures may feel heavy or contribute to heat and sweat buildup on some skin types; discontinue if congestion occurs.
