Hydrogenated Lecithin vs Mineral Oil (Paraffinum Liquidum): which Korean skincare ingredient?

| Hydrogenated Lecithin | Mineral Oil (Paraffinum Liquidum) | |
|---|---|---|
| What it is | Soy-derived phospholipid, hydrogenated so it does not go rancid. Two jobs: it emulsifies, and it forms the little bilayer spheres that brands call liposomal or capsule delivery. Whether a liposome meaningfully improves delivery depends entirely on the formula, so treat the word capsule on packaging as a claim to check, not a guarantee. | 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 | Damaged moisture barrier, Dryness & dehydration | Dryness & dehydration, Damaged moisture barrier, Flaking & peeling |
| When to use | BOTH | BOTH |
