|---|---|---|
| What it is | 화산송이 (hwasan songi) is the reddish porous scoria that covers parts of Jeju, and it became a Korean beauty signature the way volcanic mud did in Iceland — through provenance as much as chemistry. As an oil absorber it works. As proof of anything about Jeju's air or water, it is a story sold with a mask. | Charcoal binds things to its surface, which is why it works in water filters and why it looks convincing in a black clay mask. On skin it picks up surface oil during the couple of minutes it is there. The detox framing is nonsense — nothing is being drawn out of a pore, and a peel-off charcoal mask mostly removes your vellus hair. |
| Best for | Oil control, Pores & texture, Blackheads & sebaceous filaments | Oil control, Blackheads & sebaceous filaments, Pores & texture |
