| Polymethylsilsesquioxane | Witch Hazel (Hamamelis) | |
|---|---|---|
| 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. | The tightening sensation is real and almost entirely temporary. Witch hazel's tannins constrict the skin surface for a while, which reads as smaller pores in a mirror. The bigger question is the distillate: many versions carry alcohol, and on already-reactive skin that combination gives you redness dressed up as freshness. |
| Best for | Pores & texture, Rough & uneven texture, Oil control | Oil control, Pores & texture, Redness & sensitivity |
| When to use | AM | BOTH |
