Over the last 10 years, MEDIHEAL has conducted lengthy study to develop over 250 unique sheet masks in a range of cutting-edge formulas and materials. Many of these became the first of their kind in Korea, including a black mask made with real Bintochan charcoal powder, an acupressure mask designed to stimulate facial acupoints, a never-before-seen 3D ampoule mask that offers effortless application, and a two-step mask treatment with innovative packaging that’s registered as a utility model.
