CORSET Black has a patented asymmetric structure and is divided into a grip part that fixes it and a retention part that maintains the shape. This product is characterized by its embedding cog that runs in a 360° spiral. The cog of each part is “strongly incrusted” with the ideal angle, shape, and size that vary depending on the purpose, so the treatment is more effective and lasts longer than the molding cog made by applying heat and pressure. CORSET Black raises sagging cheeks and improves facial lines, and is more effective when treated with CORSET, another patented product of our company.
