Abstract
Carbon dioxide (CO2) laser resurfacing has been used as a method to treat rhytides and photodamaged skin. This laser offers several advantages over previously utilised modalities but its use has several inherent risks. This article will review important aspects of CO2 laser resurfacing including laser-skin interactions, patient selection, effective pre- and post-operative regimens and potential complications.
Highlights
During the last century, the science of dermatology has changed dramatically
Four years ago [1], laser skin resurfacing was introduced for the treatment of rhytides and photodamaged human skin and since that time it has received a great deal of attention from the media, patients and physicians of many specialties
CO2 laser resurfacing can achieve excellent results but success is dependent on a variety of factors
Summary
The science of dermatology has changed dramatically. New modalities have been invented and explored which o#er the clinician exciting treatment options. Tissue Technologies TruPulse (Albuquerque, NM) is engineered and can produce a pulse of 6 W with a pulse duration of close to 60 s This reduced pulse duration results in a more superficial tissue vaporisation and limits the zone of thermal injury. The CPG greatly increases the speed and uniformity of CO2 resurfacing and o#ers the clinician the ability to vary the pattern, size and density of pulses [3]. In general, the depth of tissue removal increases with pulse energy and number of passes [4]. Melanocytes are generally increased in number and size and melanin is unevenly distributed to the keratinocytes resulting in irregular pigmentation of the skin. Because laser resurfacing results in a controlled depth of injury, the risks of scarring and dyspigmentation are significantly decreased
