A side-by-side comparison of carbon dioxide resurfacing lasers for the treatment of rhytides
1Department of Surgery, Boston University School of Medicine, Massachusetts, USA.
Background:
The use of cutaneous resurfacing lasers to treat rhytides is widely accepted. Several carbon dioxide lasers, many using fundamentally different technologies, are available.
Objective:
The purpose of this study was to compare the results obtained and side effects after treating rhytides with 3 different carbon dioxide resurfacing lasers.
Methods:
We performed a randomized, blinded, prospective study wherein 16 subjects had either periorbital or perioral rhytides resurfaced with 1 of 3 carbon dioxide lasers on either side of the face.
Results:
We were unable to demonstrate any significant differences in improvement in rhytides, patient satisfaction, posttreatment erythema, or other side effects.
Conclusion:
Our results suggest that operator technique and patient selection are more important factors than laser type with respect to outcome.
