| Zinc PCA | Silica | |
|---|---|---|
| What it is | The quiet oil-control ingredient in mattifying Korean toners and serums. PCA is a natural moisturising factor, so unlike alcohol-heavy mattifiers it manages shine without leaving skin parched. | 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. |
| Best for | Oil control, Pores & texture, Blackheads & sebaceous filaments | Oil control, Pores & texture, Rough & uneven texture |
| When to use | BOTH | AM |
Which should you choose?
Choose Zinc PCA if your priority is Oil control; choose Silica for Oil control. Many Korean routines use both — yes — they layer well together.
