reported Robert A. Weiss, MD, of the MD Laser and Vein Institute, Baltimore, and his associates.
In a prospective, blinded study of perioral and periocular wrinkles in 40 healthy women (average age 58 years) who were nonsmokers, a 6-mm spot size diffractive lens array delivered a fluence of 0.71 J/cm2 at each focal point using 10-Hz pulse repetition at a pulse duration of 750 picoseconds. During each treatment, four passes of the 755-nm alexandrite laser (Picosure) for a total of 5,000 pulses were delivered. At 6 months follow-up, the mean Fitzpatrick wrinkle score had improved to 3.47 from the baseline average of 5.48 (P less than .05), with an overall average change in score of 1.97. Adverse events were mild, and all resolved, most within 24 hours (Lasers Surg Med. 2017 Jan;49[1]:40-44).
At 1 and 6 months, physician satisfaction ratings were 97.4% and 89.5% (extremely satisfied or satisfied), respectively. At 1 month, 42.1% of the patients were extremely satisfied, and 47.4% were satisfied. At 6 months, 42.1% were extremely likely to recommend the treatment, and 44.7% were likely to recommend the treatment.
The picosecond 755-nm alexandrite laser has been reported to be effective for tattoo removal, compared with the nanosecond domain lasers, they noted.
