| Dimethicone | Glyceryl Stearate | |
|---|---|---|
| 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. | 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 | Damaged moisture barrier, Rough & uneven texture, Dryness & dehydration | Dryness & dehydration, Damaged moisture barrier |
| When to use | BOTH | BOTH |
Which should you choose?
Choose Dimethicone if your priority is Damaged moisture barrier; choose Glyceryl Stearate for Dryness & dehydration. Many Korean routines use both — yes — they layer well together.
