Abstract:
Objective To investigate the efficacy and side effects of carbon dioxide (CO2) fractional laser for the treatment of suborbital wrinkles.Methods Twenty-one female patients with suborbital wrinkles received a single treatment of CO2 fractional laser at fluences of 20-30 mJ with density of 10 ％-15 ％.Patients were photographed standardly and evaluated at baseline,one and six months after the treatment.Wrinkle improvements were graded in 5 levels:1 (no improvement or worse),2 (1％ 25％ improvement),3 (26％-50％ improvement),4 (51％-75％ improvement),and 5 (76％-100％ improvement).Patients rated the pain intensity by a visual analog scale (VAS,0 10).The side effects,such as hyperpigmentation,were observed and recorded.Results After one month follow-up,3-level improvement was observed in 7 patients (33.3％),2-level in 9 patients (42.9％);and after six months,3-level improvement was observed in 9 patients (42.9％),2-level in 8 patients (38.1％),but there was no statistically significant difference between one month and six months (P ＞0.05).The overall patient satisfactory rate was 81.0％.The average pain of VAS was 4.24± 1.73,7 patients (33.3％) had hyperpigmentation which faded within three months,and no patients had scars.Conclusions Single CO2 fractional laser treatment can improve the suborbital wrinkles in a cerrain extent with few side effects.
