Restylane Kysse is a monophasic and sterile gel based on cross-linked hyaluronic acid. It works by increasing the volume of the dermis, and is intended mainly for correcting the shape of the lips, changing their contour, increasing the volume of the lips, as well as lifting the corners and filling fine wrinkles around the mouth. The preparation leaves a natural filling effect, and the results last up to several months after the injection. Restylane Kysse contains the addition of lidocaine, which has an analgesic effect, thus minimizing the discomfort associated with the injection.
