| Silica | Activated Charcoal | |
|---|---|---|
| What it is | The workhorse of Korean primers, sun sticks and mattifying creams. Silica is porous mineral powder: it soaks up oil and diffuses light, so shine takes longer to break through and pores look shallower than they are. The effect is optical and temporary, which is exactly what a primer should be honest about. | 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, Rough & uneven texture | Oil control, Blackheads & sebaceous filaments, Pores & texture |
| When to use | AM | PM |
Which should you choose?
