RadioFrequency (RF) Lift for Skin treatmentRadiofrequency skin tightening is a new and very promising tool for the non-surgical tightening of loose or sagging skin. In its current configuration, most patients will see at least a mild improvement, with minimal downtime and minimal risk. This technology offers a very attractive alternative to invasive "facelift" surgery in the younger patient. What is RadioFrequency (RF)?The application of non-ablative Radiofrequency (RF) energy is the most recent addition to the armamentarium in the war on the aging face. Although radiofrequency energy has been used in surgery for over 70 years, recent developments in crygogenic and computer technology have made possible the selective delivery of energy to the deep dermis and subdermal layers while protecting the epidermis. Heating in this area causes microscopic changes and collagen contraction, with subsequent collagen remodeling over the course of months. Because no external wound is created, patients can return to normal activity "immediately". How it works? The method is based on the ability of radiowaves of certain frequency to penetrate and be absorbed by body tissues. The absorption of radiowaves causes tissue heating as well as some structural molecular changes. (An essentially similar effect is used in microwave ovens where high-frequency radiowaves heat and cook food.) The skin is deep-treated with controlled doses of targeted radiowaves, while its surface layer (epidermis and upper dermis), is being cooled by a cryogenic spray to prevent open burns. The treatment produces localized heat injury of the dermis and subdermal layer as well as the collagen contraction leading to skin tightening. The subsequent healing of the microscopic dermal and subdermal lesions causes further skin tightening and also reduces the depth of wrinkles. Notably, since the skin surface is preserved, the downtime after the procedure is relatively short. Procedure and Treatment The Procedure is about 1 hour before the procedure, the patient takes the oral medication prescribed before the operation, and applies a thick layer of topical anesthetic cream (EMLA or Topicaine) to the areas to be treated. This cream should be covered with plastic wrap to keep it moist. Just before treatment, small amounts of buffered lidocaine are injected to minimize discomfort during treatment. The area to be treated is cleaned, moistened slightly, and a grid decal applied to the skin. Following treatment, patients may notice mild swelling and redness, and only rarely is even mild postoperative discomfort present. The degree of swelling is related to the amount of energy applied a higher treatment energy is more likely to result in more swelling, although for a given amount of energy, some patients will have more swelling than others. If preoperative medication is used, no driving is allowed that day. |
