PetrolatumBenefits, how to use & safety
The most effective moisture lock ever made.
What is Petrolatum?
Petrolatum is a purified mineral-based jelly and the most effective occlusive moisturiser available. Pharmaceutical-grade versions are highly refined and widely recommended by dermatologists for protecting damaged skin and locking in moisture.
How it works
It forms a breathable but water-resistant film that dramatically slows water loss through the skin. This gives the barrier time to repair and makes it ideal after serums or on rough, chapped areas.
Key benefits

- Protects chapped lips, hands and heels

Best suited for: Dry and damaged skin, lips and body. Acne-prone faces may prefer lighter occlusives.
How to use it

Safety & side effects
Refined petrolatum is considered safe and is non-comedogenic for most. Avoid unrefined industrial grades. It can feel heavy and may trap products underneath, so apply it over clean skin.
