How many treatments you need will depend mainly on how your tissue looks and feels when you come to your consultation initially. More sagging means more treatments to get the desired effect. As we age, we naturally produce less collagen, which may mean more stimulation by the device is required for more significant tightening.  You may only need between one and four treatments; over time, you will need maintenance procedures to keep the effect as we age and collagen production returns to normal. We may suggest you need a more intense type of combination treatment for your particular skin issue. It is important to manage your expectations.
