| What it is | 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. | 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 | Dryness & dehydration, Rough & uneven texture | Dryness & dehydration, Damaged moisture barrier, Flaking & peeling |
| When to use | BOTH | PM |
