Abstract

BACKGROUND:

A number of devices are available for skin rejuvenation and conventional devices include both ablative and non-ablative lasers. More recently, bipolar fractionated radiofrequency (RF) devices have been introduced.

OBJECTIVE:

To evaluate the safety and efficacy of a novel 144 pin high density tip bipolar fractionated radiofrequency (RF) device for skin rejuvenation in Fitzpatrick skin types I-IV.

METHODS AND MATERIALS:

This single-center, prospective, study enrolled 25 female between the ages of 35-60 years, with mild to moderate wrinkling based on the Fitzpatrick Wrinkle Scale. The subjects were of Fitzpatrick skin types I-IV. Each subject underwent 3 full-face treatments with a 144 pin fractional bipolar RF device at 30-day intervals. All subjects underwent clinical evaluations during the study period to evaluate for any adverse events. Subsequently, all subjects were evaluated for improvement in rhytides, dyschromias and skin texture based on photographic evaluation by blinded investigators at 6 months following the final RF treatment.

RESULTS:

A statistically significant improvement in rhytides, dyschromias and texture was noted. Adverse events were limited to mild erythema and swelling. Post-inflammatory pigmentary changes were not observed in any subjects.

CONCLUSION:

The novel 144 pin high density tip bipolar fractionated RF device is both safe and effective for facial skin rejuvenation in Fitzpatrick skin types I-IV.
