Discussion : Ablative lasers seem to achieve the highest degree of efficacy , albeit this is associated with significant pain and downtime , and the risk for long-term pigmentary changes .
Non-ablative fractional photothermolysis ( FP ) has a much safer profile but can not achieve as good cosmetic results .
The efficacies of fractional radiofrequency microneedling and radiofrequency are slightly inferior to that of FP but offer an even safer adverse profile .
Conclusion : Multiple devices have been used with varying levels of efficacy and very different safety profiles .

Efficacy of the Fractional Photothermolysis System with Dynamic Operating Mode on Acne Scars and Enlarged Facial Pores
BACKGROUND Current treatments for acne scars and enlarged facial pores have shown limited efficacy . OBJECTIVE To evaluate the efficacy and safety of the fractional photothermolysis system ( FPS ) with dynamic operating mode on acne scars and enlarged pores . MATERIAL S AND METHODS Twelve patients with mild to moderate atrophic acne scars and enlarged pores were included in this study . Three sessions of FPS treatment were performed for acne scars and facial pores monthly . Two blinded dermatologists who compared before and after photos based on a quartile grading scale conducted objective clinical assessment s of acne scar– and facial pore – treated areas . We took a biopsy immediately after one treatment with the laser from one of the authors to assess the histologic effects of the laser on facial pores . RESULTS Follow-up results at 4 months after the last treatment revealed that , of the 12 patients , for acne scars , five demonstrated clinical improvements of 51 % to 75 % and three demonstrated improvements of 76 % to 100 % , and for facial pores , five demonstrated moderate clinical improvements of 26 % to 50 % and three demonstrated improvements of 76 % to 100 % . Side effects , including pain , post-treatment erythema , and edema , were resolved within 1 week . CONCLUSION We suggest that the FPS may provide a new treatment algorithm in some cases with acne scars and enlarged pores . Considering the lack of placebo-controlled , split-face design of our study , optimized , prospect i ve studies should be conducted to fully assess the efficacy of FPS with dynamic operating mode
