The amount of Wrinkle Relaxer a patient needs depends entirely on the size of the facial muscles and the number of areas that require treatment. The amount varies between twenty-five units and a hundred units of Wrinkle Relaxer. For instance, for the wrinkles located between the eyebrows, you will require around thirty units of Wrinkle Relaxer; however, for the forehead and other larger areas, you can expect to require up to ninety units. It all depends on the number of wrinkles you have and your face, how strong your facial muscles and how thick your skin is. The amount of Wrinkle Relaxer administered to your skin will be settled by the surgeon before the injections.
