We, mayunowa, have established a new cosmetics company for the manufacture of cosmetic products, focusing skin's immune function. All the ingredients we use have excellent biocompatibility. We use eco-friendly ingredients. We procure plant-based ingredients from recycle-oriented farmers. We select materials with minimum residual risks and those that are produced without using alcohol or other solvents that may have negative impacts on the environment. These selections are made based on our strict standards. We have developed our original "Kinu Biyo" (Silk Beautification), in which we polish up the skin using the Sericin Beaute water-warmed brushes. We have developed this method by combining the master craftsmanship of the Kumano Fude brush and purely-domestic rare silk. It is a relaxation technique that leads one into a deep sleep by approaching the fascia and meridians deep within the skin. Our Silk Beautification, in which all materials are designed to be friendly to both the skin and the environment, is employed by many esthetic salons in luxury hotels as a purely Japanese spa menu for quickly healing the eyes, skin and minds, away from stressful daily life.
