Fractional ablative carbon dioxide laser resurfacing for skin rejuvenation and acne scars in Asians.
BACKGROUND AND OBJECTIVES Ablative fractional resurfacing ( AFR ) is a new modality for photorejuvenation and acne scars which combines carbon dioxide ( CO₂ ) laser ablation with fractional photothermolysis . The objective is to evaluate the efficacy and side effects of a new fractional CO₂ ablative device ( Fraxel Re : pair ) for skin rejuvenation and acne scars in Asians . MATERIAL S AND METHODS Nine patients underwent one full-face treatment . The energy levels ranged from 30 - 70 mJ with coverage between 30 % and 45 % . Improvement in skin texture , laxity , wrinkles , enlarged pores , overall pigmentation irregularity , and adverse effects were assessed up to 6 months post-treatment . St and ardized photographs using the Canfield Visia CR system ® were assessed by two independent observers . Subjective improvement was assessed by patient question naires . RESULTS Nine Chinese patients ( skin types III and IV , mean age 44.8 ) were included . Statistically significant improvements were seen for skin texture , skin laxity , wrinkles , enlarged pores , and acne scars . The post-inflammatory hyperpigmentation rate was 55.5 % and 11.1 % at 1 and 6 months post-treatment , respectively . Eighty-six percent of patients were overall satisfied to very satisfied with the treatment . CONCLUSION Ablative fractional CO₂ laser resurfacing was overall safe and effective for skin rejuvenation and acne scars in Asians . However , in view of the high post-inflammatory rate and the statistically significant but only mild to moderate improvement after a single treatment as observed in this study , there is a need to review the current role of fractional ablative CO₂ laser treatment as compared to fractional non-ablative for skin rejuvenation and acne scar treatment in Asians
