| Alcohol Denat. | Activated Charcoal | |
|---|---|---|
| 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. | 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 | Oil control, Blackheads & sebaceous filaments, Pores & texture |
| When to use | BOTH | PM |
Which should you choose?
