Outcome Measures
Primary Outcomes (1)
Global assessment of acne scar
5-point grading of acne scar quartile assessment of acne scar improvement through comparing the photos taken before treatment and after treatment
12 weeks
Secondary Outcomes (2)
ECCA
12 weeks
Adverse effect

Study Arms (2)
microneedling radiofrequency device
EXPERIMENTALmicroneedling radiofrequency
bipolar radiofrequency device
ACTIVE COMPARATORbipolar radiofrequency treatment
Interventions
Microneedling radiofrequency device is composed of 49 insulated microneedle which emit radiofrequency from the needle tip. This radiofreqeuncy generates dermal heat which evokes biological effect.
bipolar radiofrequency instrument gives out bipolar radiofrequency from the hand piece tip. This bipolar radiofrequency generates dermal heat which has a lot of bilogical effect.
