How does the bubbling charcoal mask work and what should I expect during use?

When you apply the sheet mask, the serum begins to react with the air and forms a fine foam across the surface. This bubbling action is not just visual — it creates a light mechanical stimulation that helps dislodge residue, excess sebum, and dead skin cells sitting on the skin's surface. At the same time, the activated charcoal in the formula acts like a porous sponge: its structure binds dirt and oil so they can be rinsed away when you remove the mask.

During the 10–15 minutes the mask stays on, you will feel a gentle tingling or tickling sensation as the foam expands. This is normal and indicates the reaction is active. The serum base is designed to keep the skin from feeling tight or stripped once the foam is rinsed off. After removal, massage any remaining essence into the skin, then rinse with lukewarm water. The result is typically a cleaner-feeling surface with a smoother touch, not a clinical "deep pore clean" — charcoal works on the uppermost layer only.
