CO2 laser resurfacing of facial rhytides and acne scars can be a very safe procedure by an experienced laser operator. However, careful patient selection, thorough patient instruction, and proper aesthetic analysis of treatment sites must be followed to insure the most favorable outcomes with CO2 laser resurfacing.

Successfully combining ablative technology with FP, AFR treatments constitute a safe and effective treatment modality for acneiform scarring.

Treatment of facial acne scars with a diffractive lens array and 755-nm picosecond laser produced improvement in appearance and texture at 3 months after the last treatment, with objective findings similar to those published for a series of fractional ablative laser treatments. Histologic findings suggest that improvement in scarring from this treatment goes beyond remodeling of collagen.

Background: Cryogen spray cooling can be used to provide epidermal protection while still achieving spatially selective photocoagulation in the upper dermis. The objective of this study is to determine the efficacy and safety of cryogen spray cooling in combination with a nonablative Nd:YAG (= 1320 nm) laser treatment of facial rhytides in human volunteers. Observations: Thirty-five adults with bilateral periorbital rhytides were treated with cryogen spray cooling in combination with 3 nonablative laser treatments performed sequentially at intervals of 2 weeks. Small but statistically significant improvements were noted in the mild, moderate, and severe rhytid groups 12 weeks after the final laser treatment. A final assessment performed 24 weeks after the last treatment showed statistically sig
