| Silica | Alcohol Denat. | |
|---|---|---|
| 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. | 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. |
| Best for | Oil control, Pores & texture, Rough & uneven texture | Oil control |
| When to use | AM | BOTH |
