Tight, flaky or rough; little visible oil. Craves hydration + barrier support.
Ranked by hero status, breadth of documented benefit, and fit with dry skin. We rank ingredients, never specific products.
1
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.
2
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.
3
The most effective occlusive in common cosmetic use, and the most unfairly maligned. Cosmetic-grade mineral oil is highly refined, chemically inert and rates as non-comedogenic in testing — the acne folklore comes from crude industrial grades, not from the ingredient in your cleansing oil. It hydrates nothing itself; it simply stops water leaving.
4
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.
