Tightening of saggy skin is now possible by using the Thermi-Smooth System which is a non-invasive Radio-frequency (RF) device that delivers RF energy into the dermis, stimulating new collagen formation, reducing the appearance of fine lines, and tightening the loose skin of the face and body. A series of treatments are required in order to achieve desirable results. Slight warm yet very comfortable sensations may be experienced while undergoing treatments. Results are cumulative and may require several treatments. The most common areas treated are eyelids, cheeks, neck, chest, abdomen, arms, and legs. Thermi-Smooth is also very effective in treating cellulite.
