The Medicube Exosome Cica Serum (also known as the Exosome Cica Ampoule) is a breakthrough treatment for sensitive and troubled skin. It utilizes nano-sized Exosome Cica particles—which are 1/510th the size of a pore—to penetrate deeper and faster than standard Centella extracts. This 84% high-concentration formula is designed to provide immediate relief for skin irritation, redness, and rough texture. By enhancing cellular communication, it helps the skin recover from external stressors while balancing sebum production and providing a burst of moisture, resulting in a clearer, “glass-skin” finish.
