| Caprylic/Capric Triglyceride | Mineral Oil (Paraffinum Liquidum) | |
|---|---|---|
| What it is | Coconut-derived, fractionated, and nothing like coconut oil in behaviour. It is one of the most-used emollients in cosmetics because it is light, spreads beautifully and stays fresh for years. If a Korean cleansing oil or ampoule feels silky rather than greasy, this ester is often the quiet reason. | The most effective occlusive in common cosmetic use, and the most unfairly maligned. Cosmetic-grade mineral oil is highly refined, chemically inert and rates as non-comedogenic in testing — the acne folklore comes from crude industrial grades, not from the ingredient in your cleansing oil. It hydrates nothing itself; it simply stops water leaving. |
| Best for | Dryness & dehydration, Damaged moisture barrier | Dryness & dehydration, Damaged moisture barrier, Flaking & peeling |
| When to use | BOTH | BOTH |
