Science
Mechanism of Action
Functioning primarily as an occlusive emollient, Paraffinum Liquidum establishes a physical, water-resistant barrier upon application. This inert film physically blocks the escape of moisture from the skin's surface, thereby enhancing hydration levels and contributing to skin suppleness. Additionally, this barrier offers a protective shield against external environmental stressors.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has extensively evaluated highly refined white mineral oil, concluding its safety for topical application at all concentrations, citing no scientific evidence of hazard. Regulations in Europe mandate strict purity standards, particularly concerning polycyclic aromatic hydrocarbons (PAHs). The FDA also permits its use as a direct food additive and in certain over-the-counter skin protectant drugs. For lip applications, food-grade purity is recommended.
