|---|---|---|
| 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. | You have read this name a hundred times on Korean sunscreen and cushion labels without registering it. It is a synthetic ester chosen for one quality: a dry, fast-spreading slip that stops filter-heavy formulas feeling like grease. Purely a texture ingredient, and an unusually good one. |
| Best for | Damaged moisture barrier, Dryness & dehydration | Dryness & dehydration, Rough & uneven texture |
| When to use | BOTH | BOTH |
Which should you choose?
