| What it is | 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. | The most sensible boring oil on the shelf. Sunflower oil is linoleic-rich, which is the profile associated with a more comfortable barrier, and it is light enough for skin that dislikes heavier oils. It is a carrier in more Korean products than you would guess — often listed simply as Helianthus Annuus Seed Oil. |
