| What it is | The word alcohol on a label has cost this ingredient a lot of unearned suspicion. Cetearyl alcohol is a fatty alcohol — a waxy solid, closer to shea butter than to vodka — and it thickens and softens rather than dries. If a cream feels rich and stable, this is usually part of the reason. | 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. |
