Thermage is a non-surgical procedure that is used to tighten and contour the skin. Radio-frequency technology stimulates and tightens existing collagen and promotes growth. Thermage procedures can effectively and safely treat skin on most body parts, including the face, eyes, lips, tummy, arms, hands, thighs and buttocks. Unlike many laser procedures requiring four or more sessions, a thermage treatment delivers results in one treatment for most patients. A single session can take up to two hours; improvements can be seen for up to a year.
