| Glyceryl Stearate | Hydrogenated Lecithin | |
|---|---|---|
| What it is | 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. | 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. |
