| Dimethicone | Hydrogenated Lecithin | |
|---|---|---|
| What it is | Silicones took an undeserved reputational beating. Dimethicone does not suffocate skin — it is a well-tolerated film former, and it is most of the reason a Korean sunscreen applies so smoothly. | 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 | Damaged moisture barrier, Rough & uneven texture, Dryness & dehydration | Damaged moisture barrier, Dryness & dehydration |
| When to use | BOTH | BOTH |
