Outcome Measures

Primary Outcomes (1)

  • Change in best overall cosmetic appearance (right side or left side better)rated by a blinded dermatologist from baseline to week 16

    The primary outcome was a blinded rating of the treatment area (Fractional Radiofrequency Versus Fractional Photothermolysis) with the best cosmetic appearance. A dermatologist will blindly evaluate the treated areas of each side from live subjects at baseline and on the final follow up visit (week 16).

    1 hour at baseline and week 16

Study Arms (2)

Fractional Radiofrequency

ACTIVE COMPARATOR

Subjects will be randomly assigned to receive fractional radiofrequency treatment to either the right or left side of the face and the contralateral side will receive 1550-nm fractional photothermolysis. Subjects will receive treatments at baseline, week 4, and week 8 for a total of three treatments. Follow up visits will take place at week 16, two months following the last treatment visit.

Device: Fractional Radiofrequency

1550-nm Fractional Photothermolysis

ACTIVE COMPARATOR

Subjects will be randomly assigned to receive fractional radiofrequency treatment to either the right or left side of the face and the contralateral side will receive 1550-nm fractional photothermolysis. Subjects will receive treatments at baseline, week 4, and week 8 for a total of three treatments. Follow up visits will take place at week 16, two months following the last treatment visit.

Device: 1550-nm Fractional Photothermolysis
