Innisfree volcanic clusters are naturally oil-absorbing hardened lava designed to visibly minimize pores. Naturally formed volcanic cluster capsules are blended into the formula to absorb excess sebum and exfoliate dead skin. They have a rough texture and work to improve congested and enlarged pores. Lactic Acid and Walnut Shell Powder help further refine to help smoothen skin texture and minimize look of enlarged pores. Jeju volcanic cluster collection includes a cleanser that can be used daily, a scrub that can be used 1-2x per week, a bi-phase toner, daily stick, wash off capsule mask, jar clay mask and mousse clay mask, and strips. There is also wash off, melt off and peel off masks that can be used 1-2x per week, so that you can choose which texture, formula, and application is best for you. During the time of volcanic eruptions on Jeju Island, hot lava fragments formed clusters as they solidified. Found nowhere else on earth, these naturally porous clusters are packed with minerals and have the ability to absorb excess oil and impurities from pores.
