Their Jeju Volcanic products utilize volcanic clusters which are basically volcanic minerals found around Jeju volcanoes. They are super effective at clearing out blackheads and impurities. Both the volcanic pore scrub foam and clay mask are popular best-sellers. The scrub is gentle enough to use a couple times a week depending on the sensitivity of your skin. The super volcanic pore clay mask can be used weekly or bimonthly based on your specific pore concerns. The original pore clay mask is better for individuals with smaller pores or more sensitive skin.
