Hypothesis: Of techniques currently available for facial skin appearance improvement, nonablative laser therapy offers subtle improvements with an excellent risk-benefit ratio.
The subtle improvements in skin texture and wrinkling after nonablative laser treatment are preferred by many patients to the more obvious improvements after ablative laser resurfacing, because the nonablative laser treatment has a lower risk of complications, shorter recovery time, and less disruption of regular activities. In 1993, the first high-energy resurfacing carbon dioxide lasers became available for skin resurfacing. These carbon dioxide resurfacing lasers effectively treat facial rhytids and actinic changes.1,2 They are used to ablate the epidermis and partially ablate the dermis, removing skin changes due to photoaging. They stimulate neocollagen formation and tissue tightening,3,4 resulting in long-term skin texture and wrinkle improvement.
