| Zinc PCA | Kaolin Clay | |
|---|---|---|
| What it is | The quiet oil-control ingredient in mattifying Korean toners and serums. PCA is a natural moisturising factor, so unlike alcohol-heavy mattifiers it manages shine without leaving skin parched. | 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, Pores & texture, Blackheads & sebaceous filaments | Oil control, Pores & texture, Blackheads & sebaceous filaments |
| When to use | BOTH | PM |
Which should you choose?
