Plasma Skin Resurfacing
Another new technology that shows promise in improving photodamaged skin in initial studies is plasma skin resurfacing. Rather than using light or radiofrequency that are common in other laser resurfacing procedures, plasma resurfacing uses a nitrogen gas to generate plasma energy -- which is delivered to the targeted epidermis and dermis in either multiple, low-energy or single, high-energy millisecond pulses. Over a period of three to 10 days, depending on the level of energy used, the outermost layer of skin remains intact and acts as a "biological dressing" to protect the new epidermis and dermis forming underneath.
In a study published in the February 2007 issue of the Archives of Dermatology, Dr. Dover and his colleagues evaluated the effectiveness of multiple, low-energy, full-face plasma skin resurfacing treatments compared to a single, high-energy treatment. While single, high-energy plasma resurfacing treatments have been demonstrated to achieve successful results, patients typically require a week or more of healing time. Dr. Dover explained that his study was conducted to determine if comparable results could be achieved with less downtime by using multiple treatments at a lower energy.
"In the eight patients we studied that underwent full-face treatments
every three weeks for a total of three treatments, we found a 37 percent
