| Zinc PCA | Activated Charcoal | |
|---|---|---|
| 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. | Charcoal binds things to its surface, which is why it works in water filters and why it looks convincing in a black clay mask. On skin it picks up surface oil during the couple of minutes it is there. The detox framing is nonsense — nothing is being drawn out of a pore, and a peel-off charcoal mask mostly removes your vellus hair. |
| Best for | Oil control, Pores & texture, Blackheads & sebaceous filaments | Oil control, Blackheads & sebaceous filaments, Pores & texture |
| When to use | BOTH | PM |
Which should you choose?
