⏱ 1 min read
Quick answer: How does Activated Charcoal work? Activated charcoal is carbon processed to create an enormous porous surface area, which lets it adsorb molecules onto that surface. In water treatment this is genuinely powerful. On skin, in a mask worn for a few minutes, it can pick up some surface oil and residue.

Activated charcoal is carbon processed to create an enormous porous surface area, which lets it adsorb molecules onto that surface. In water treatment this is genuinely powerful. On skin, in a mask worn for a few minutes, it can pick up some surface oil and residue. It cannot reach inside a pore, and adsorption of a substance onto carbon is not the same thing as drawing anything out of skin.

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.
