Olive Oil (including refined and extra-virgin forms)
Olive oil is prized for its high oleic acid content — a monounsaturated fat that supports the skin barrier, leaves the skin feeling soft, and creates a creamy, mild lather in soap. Even refined olive oil retains these key fatty acids that make it such a classic soap ingredient.
What it does for skin:
- Supports natural skin-barrier function
- Provides gentle conditioning
- Adds creaminess to lather
- Reduces moisture loss
