iMeso 【Authentic Nano Size】 Facial Device Penetration Beauty Needle Eye and Mouth Intensive Care The beauty device "iMeso" is exclusively sold at medical institutions. Developed with advanced technology, the "Meso Chip" has 100nm fine protrusions that create tiny holes only in the stratum corneum without damaging the skin. Because the lotion and serum enter these tiny holes, they penetrate the stratum corneum more effectively than skincare with cotton or your hands. Recommended for those who want to achieve firm and moisturized skin, and those who want to easily perform care similar to aesthetic medicine at home.
