| Hydrogenated Lecithin | Mayu (Horse Oil) | |
|---|---|---|
| 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. | 마유 (mayu) is rendered horse fat, a Jeju souvenir-shop staple and a genuine folk remedy for chapped winter skin. Its fatty acid mix is unusually similar to human sebum, which is the usual explanation for why it absorbs so well. That similarity is documented; the leaping claims about regeneration are not. Not for vegans, obviously. |
| Best for | Damaged moisture barrier, Dryness & dehydration | Dryness & dehydration, Damaged moisture barrier, Flaking & peeling |
| When to use | BOTH | PM |
