What Paraffin does

Seals in moisture on the skin
Adds slip and a smooth glide
Firms up balms, lipsticks and mascaras

Paraffin is a wax made during petroleum refining. It is purified into a solid used in cosmetics. It stays firm in the jar and leaves a smooth, slightly waxy film on the skin.

Formulators use paraffin to firm up balms, lipsticks and mascaras, and to add slip to creams. Because it forms a film, it slows water loss from the skin's surface, so it is often used in products meant to lock in moisture. In large amounts it can feel heavy, so it is often blended with lighter oils and water-based ingredients.

Frequently asked questions

Is paraffin the same as paraffinum liquidum?

Not quite. Paraffin is a solid wax, while paraffinum liquidum is a liquid oil, also called mineral oil. Both come from petroleum and belong to the same broad family, so they share the same sealing behavior and the same preference-based concerns.

Does paraffin cause breakouts?

Everyone reacts differently. Some people with acne-prone skin prefer to avoid heavy, sealing ingredients like paraffin, as a matter of personal preference. If a product feels too heavy or breaks you out, try a lighter formula and see how your skin responds.
