In our reference data, Mineral Oil (Paraffinum Liquidum) can feed Malassezia (fungal acne).
Mineral Oil (Paraffinum Liquidum) is a highly refined, inert petroleum-derived oil used as an occlusive agent to reduce transepidermal water loss and soften skin. It functions as a base/formulation ingredient rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
| Skin feel heaviness or greasy/occlusive sensation | Common | Cosmetic, related to its occlusive nature; not a true adverse reaction. |
| Comedogenicity (clogged pores/breakouts) | Uncommon | Cosmetic-grade refined mineral oil is generally considered low/non-comedogenic; reports are largely anecdotal. |
| Folliculitis or acneiform eruption with heavy occlusion | Rare | Mostly with industrial-grade or heavily occluded application, not refined cosmetic grades. |
| Allergic contact dermatitis | Very rare | Mineral oil is largely inert; sensitization is exceptionally uncommon. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
