| Cetearyl Alcohol | Hydrogenated Lecithin | |
|---|---|---|
| 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. | Soy-derived phospholipid, hydrogenated so it does not go rancid. Two jobs: it emulsifies, and it forms the little bilayer spheres that brands call liposomal or capsule delivery. Whether a liposome meaningfully improves delivery depends entirely on the formula, so treat the word capsule on packaging as a claim to check, not a guarantee. |
| Best for | Dryness & dehydration, Damaged moisture barrier, Flaking & peeling | Damaged moisture barrier, Dryness & dehydration |
| When to use | BOTH | BOTH |
