rest as Fitzpatrick skin type IV. Subjects showed a symmetrical, moderate level of baseline facial photoaging, with a mean GPS score of 2.67, and APS scores of 2.67 and 2.78 for pigmentation and wrinkles, respectively. Complicating skin conditions included melasma on three subjects and rosacea on one subjects.
Evaluation of Efficacy
After four treatments, significant improvement in photoaging was observed at two-month follow up on the treated side of the face (Figures 1 and 2) compared to the control side (Figure 3), with GPS score decrease from 2.67 to 1.44 (P=0.005; Table 1). More significant improvement in wrinkles (Figure 4) was observed than that in pigmentation (Figure 5), with the APS score decrease from 2.78 to 1.89 (P=0.005). Treatment results improved gradually throughout the treatment regimen and achieved even better improvement at two-month follow up (Table 2). Furthermore, skin tightening was perceived in all subjects, and nasolabial folds improved in 60% of the subjects on the treated side of face.
Evaluation of Treatment-Associated Complications
Pain was the major treatment associated complication during the treatment process and was quantified immediately
