erythema and mild transient hyperpigmentation 2
days after the fourth session. This complication
might have occurred as a result of uneven contact
of the treatment tip with skin surface, resulting in an
accumulation of RF energy in a single treatment area.
This complication subsided without relapse. One
obvious limitation to our study is the relatively small
number of volunteers. Nevertheless, the results
showed evidence of clinical and histologic improve-
ment after RF treatment. Although previous publica-
tions have suggested improvement after RF with skin
changes, including face tightening, few have histo-
logically analyzed the skin of the volunteers
In conclusion, monopolar RF is an effective and
valuable procedure that can be used to tighten and
rejuvenate photoaged skin, and contour facial skin
laxity. This modality stimulates the repair process,
and reverses the clinical, and the histopathological,
signs of aging, with the advantage of relatively risk-
free procedure and with little downtime.
