ParaffinBarrier
A solid petroleum-derived wax that hardens balms and sticks and leaves a protective surface film.
What it does
Paraffin is a solid, refined petroleum wax (distinct from liquid mineral oil). It gives structure and hardness to balms, sticks, and ointments and leaves a smooth occlusive film that slows water loss from the skin surface. It is a structuring and barrier-film ingredient rather than an active.
