| Cetearyl Alcohol | Glyceryl Stearate | |
|---|---|---|
| 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. | An emulsifier built from glycerin and a fatty acid, and one of the most common ways a Korean emulsion gets its texture. It is structural rather than active: no emulsifier, no lotion, just an oily layer floating on water. It also happens to feel softening on skin, which is a useful bonus. |
| Best for | Dryness & dehydration, Damaged moisture barrier, Flaking & peeling | Dryness & dehydration, Damaged moisture barrier |
