| Polymethylsilsesquioxane | Activated Charcoal | |
|---|---|---|
| What it is | The 'pore filter' effect in a jar, and the reason a Korean primer can make your nose look airbrushed in about four seconds. These are tiny hard spheres that sit on the surface and bounce light in all directions. Nothing is being treated. Wash it off and the pores are exactly as they were. | 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 | Pores & texture, Rough & uneven texture, Oil control | Oil control, Blackheads & sebaceous filaments, Pores & texture |
| When to use | AM | PM |
