Mineral Oil

What it does

Mineral oil is an occlusive emollient that sits on the skin's surface, creating a waterproof barrier that prevents transepidermal water loss. It is non-comedogenic at typical cosmetic concentrations and widely used in creams, lotions, and oils for its stability and affordability. It does not penetrate deeply into skin or get absorbed systemically in meaningful amounts.

Benefits

• Effective occlusive barrier reduces water loss
• Softens and smooths skin texture
• Hypoallergenic; rarely causes sensitization
• Stable, cost-effective ingredient
• Non-comedogenic when used appropriately

Who it suits

• Dry, dehydrated skin
• Sensitive skin
• All skin types (when not overused on oily skin)

How to use

Apply to damp skin as part of a moisturizer or use alone as an occlusive final layer. Use sparingly on oily skin; more generously on dry areas.
