Brief summary

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.

Detailed description

Thirty patients suffering from moderate or severe acne scars were randomly assigned into two equal groups. Group A (MRF group): received 2 sessions per week with MRF for 8 weeks. Group B (PDL group): received 1 session per week with PDL for 8 weeks. The severity of acne scars was assessed before and after treatment by using the clinical evaluation scale for acne scarring (ECCA) scale and the self-assessment of clinical acne-related scars (SCARS) scale. Quality of life and the emotional impact of acne scars were evaluated by the facial acne scar quality of life (FASQoL) scale.

Interventions

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.

DEVICEPulsed dye laser

PDL was applied for the affected areas with no pre-treatment regimens or topical anaesthetics. There was no requirement for skin cooling.

Design outcomes

Primary

MeasureTime frameDescription
acne scars severity by investigatorafter 8 weeks of interventionClinical 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.
acne scars severity by the participantafter 8 weeks of interventionSelf-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.

Secondary

MeasureTime frameDescription
emotional, social functioning and work/school effect of scarsafter 8 weeks of interventionFacial 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.
