A new skin rejuvenation technology, called Plasma Skin Resurfacing, or Portrait Plasma, was introduced in February 2005. The technology uses plasma energy (heat and light energy) to rejuvenate the skin from the deeper layers outwards. While new skin regenerates, the outer layers of the skin act as a natural bandage. When the outer layers peel off in the week after treatment, the new skin emerges. The process prevents or minimizes the raw appearance that follows laser treatments. This system uses radio waves to "excite" nitrogen gas, resulting in the release of energy. According to the manufacturer, skin regeneration using the Portrait Plasma system is rapid, and satisfaction with the procedure appears high. Long-term follow-up studies are not available yet for this new method.
Other Exfoliation Procedures
Cold Ablation. Cold ablation, called coblation for short, delivers saline (salt water) to the skin, through which a cool electric current is passed. A subsequent reaction heats and vaporizes the top shallow layer of skin. The procedure is very specific and appears to minimize any damage to other areas of the skin.
Radiofrequency Resurfacing. A promising technique uses low radiowave energy to resurface the skin. Preliminary research indicates that this procedure may eventually be as effective as laser surgery in reducing severe wrinkles around the eyes and mouth, with minimal pain and a shorter recovery time. In a 2003 study, one treatment with a topical anesthetic resulted in tighter facial skin for 14 out of 15 patients within 12 weeks. All but one patient returned to normal activity immediately afterward. A small clinical trial published in Dermatology Surgery found that a noninvasive radiofrequency technique called NARF safely and effectively improved drooping lower eyelids.
Intense Pulsed Light. Intense pulsed light (IPL) uses filters to deliver different wavelengths of light. Doctors use it to treat a number of photoaging skin problems, and it appears to have long-term effects. Typically, four to six treatments are performed over a four-month period. Each treatment takes 15 - 20 minutes. Unlike laser light, which uses one color wave-length (such as green or red), intense pulsed light starts with a full spectrum of light. It then allows the doctor to selectively block off specific wavelengths, depending on how shallow or deep the procedure should go. IPL machines are less expensive and safer than lasers.
