Monopolar Radiofrequency Versus Pulsed Dye Laser for Treatment of Acne Scars (MRFPDL)
Monopolar Radiofrequency Versus Pulsed Dye Laser for Treatment of Acne Scars: A Randomized Clinical Trial
Background: The acne scar is a common disorder characterized by skin eruption or abnormalities on face, chest, and/or back in the adolescence which affect the cosmetic appearance.
Purpose: The main aim of this study was to investigate whether monopolar radiofrequency (MRF) or pulsed dye laser (PDL) is more effective in the cases suffering from acne scars in the form of reducing acne scars and improving the cosmetic appearance.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: monopolar radiofrequency (MRF) group
Monopolar Radiofrequency Diathermy (LVT-250, Korea) was used at average energy160-180 W, main power 50/60 Hz, 40˚C ~ 45˚C Temperature, RF output 470 kHz, 20 mm electrode size.
|
The RF electrode was moved randomly for 30 seconds over each scar.
The total duration of the treatment session is only 5 minutes for each cheek.
It takes 15 minutes if the forehead and 2 cheeks are affected.
|
Active Comparator: Pulsed dye laser (PDL) group
Flash lamp pulsed dye laser; Candela SPTL-1 (Candela Corp., Wayland, Mass.) with the following parameters: (585nm wavelength, 450 msec pulse duration, 6.5 to 7.5 J/cm² energy density and 5or 7mm spot size).
|
PDL was applied for the affected areas with no pre-treatment regimens or topical anaesthetics.
There was no requirement for skin cooling.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
acne scars severity by investigator
Time Frame: after 8 weeks of intervention
|
Clinical evaluation scale for acne scarring.
Using this scale, the type of scar was defined by the qualitative descriptions of scars, which is then accompanied by a numerical score (0-4) and then multiplied by (15-50) which is a weighting factor of clinical severity, the total possible score is from 0 to 540.
Higher score means worse outcome while lower score means better out come.
|
after 8 weeks of intervention
|
acne scars severity by the participant
Time Frame: after 8 weeks of intervention
|
Self-assessment of clinical acne-related scars questionnaire.
It consists of 5-items with 1 hypothesized domain which asks patients to assess acne scars severity as seen in the mirror.
The total possible score is from 0- 20.
Higher score means worse outcome while lower score means better out come.

after 8 weeks of intervention

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
emotional, social functioning and work/school effect of scars
Time Frame: after 8 weeks of intervention
|
Facial acne scar quality of life scale.
It is a tool formed of 10-items with 3 domains to assess the emotional, social functioning and work/school effect of scars on a 5-point rating scale The total possible score is from 0- 40.
Higher score means worse outcome while lower score means better out come.
