| Alcohol Denat. | Kaolin Clay | |
|---|---|---|
| What it is | The single most argued-about line on a Korean sunscreen label. Denatured alcohol is why that sunscreen feels like nothing and vanishes under makeup — it flashes off and leaves the filters behind. It genuinely stings compromised or sensitised skin. The claim that it damages a healthy barrier at cosmetic levels is far shakier than the internet suggests. | The gentlest of the common cosmetic clays, and the one Korean wash-off masks lean on when they want oil control without a stripped face. Kaolin soaks up sebum sitting on the surface. It does not reach into a pore, dissolve a blackhead or shrink anything — those are jobs for a BHA, if they are jobs at all. |
| Best for | Oil control | Oil control, Pores & texture, Blackheads & sebaceous filaments |
| When to use | BOTH | PM |
Which should you choose?
