Although CO2 lasers have been available to the cosmetic surgeon for more than 20 years, it is only recently that the ultrapulse mode has made the laser user-friendly. Now, tissue can be vaporized without significant charring. To shorten our learning curve with this treatment modality, various skin lesions were ablated with variable spot sizes and energy settings. Our results are presented as personal guidelines. Large and small areas may be resurfaced. If occlusive dressings are used, rapid reepithelization occurs across previous skin lesions or scars. This results in the appearance of rejuvenation. The only troublesome sequela has been persistent erythema similar to that seen after a phenol peel.
