MaiLi Define Lidocaine is based on hyaluronic acid (18 mg/ml) and is designed to create shapes and definitions for the facial area. It can fill deep lines and wrinkles like marionette lines and nasolabial folds or improve the volume of the lips. Due to the spring-like elasticity gel, facial movements will remain unaffected. With the high amount of hyaluronic acid, Maili Define helps to plump the skin and make it appear denser and more hydrated. The results can last up to 12 months.
