Comparison of a fractional bipolar rediofrequency device and a fractional erbium : glass 1550 NM device for the treatment of atrophic acne scars
Abstract:
The objective of the study was to compare the effectiveness and side effects of
fractional bipolar radiofrequency with fractional erbium: Glass in atrophic acne scar
treatment. Twenty Thai subjects with atrophic acne scars received three split-face
monthly treatments, one side with fractional bipolar radiofrequency, and the other
with fractional erbium: Glass. The improvement of acne scars was evaluated at four
weeks after the last treatment. The side effects were recorded after each treatment.
The study found significant improvement in acne scars after treatment with both
devices without statistically significant difference between them. The side effects of
both devices were pain, transient facial erythema and scab formation. In conclusion,
fractional bipolar radiofrequency and fractional erbium:.Glass have similar
effectiveness for atrophic acne scar treatment.
