Fortunately, the laser industry and technology has come a long way in recent years. Not only are today’s lasers more effective, they are also much more comfortable. This is due in large part to dynamic cooling or DCD features built into the system. However, at this laser center, clients can also opt for Pro-Nox for nearly any procedure. This patient-controlled device delivers a blend of oxygen and nitrous oxide for maximum comfort with no drowsiness afterward. Topical numbing can be used before treatment as well if desired.
