Exion HA (Hyaluronic Acid), formerly known as Exilis, uses radiofrequency and ultrasound to promote hyaluronic acid production in the skin. Profound hydration and collagen stimulation is created, resulting in immediate smoothing of fine lines by plumping the skin. It is completely non-invasive and comfortable with no downtime. It can also enhance the effects of dermal fillers or be used as an alternative to fillers.  Results are cumulative, noticed immediately and may last for several months. Follow-up treatments are recommended every 3 to 4 months to maintain results.
