How Silica works 실리카
Cosmetic silica is a porous mineral powder with an enormous internal surface area, so it soaks up sebum as it appears and delays visible shine. Its particles also scatter incoming light rather than letting it reflect straight back, which softens the visual contrast that makes pores and fine lines read as sharp edges. Both effects are physical, immediate and last only until the powder is saturated or washed off. Silica also comes in different particle shapes, and spherical grades feel markedly smoother than irregular ones.

How long does Korean skincare take to work?
Most skincare, Korean or otherwise, needs time. Hydration benefits can appear quickly, but visible changes in tone, texture or fine lines typically take several weeks to a few months of consistent use, roughly one skin cycle or more. Sun protection and patience matter more than any single product.
Does Korean skincare work for deeper skin tones?
The skincare does — hydration, barrier support and soothing actives are not tone-specific. The friction points are mineral sunscreens that leave a cast and a colour-cosmetics shade range that has historically been narrow.
