Treatment and study plan

microneedling radiofrequency device

Device

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.

Other names: INFINI(Lutronics, Goyang, Korea)

bipolar radiofrequency

Device

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.

Other names: Polaris(syneron, israel)

Primary outcomes

  1. Global assessment of acne scar

    Time frame: 12 weeks

    5-point grading of acne scar quartile assessment of acne scar improvement through comparing the photos taken before treatment and after treatment

Secondary outcomes

  1. ECCA

    Time frame: 12 weeks

    quantitative assessment of acne scar ECCA assessment is established by previous article. this method quantifies severity of acne scar by counting the number of acne scar categorized by their shape. Then, the number of scars are multiplied by weighing factors determined by scar types. ECCA is the total sum of these points. please refer the Dreno et al, Dermatology, 2007;214:46-51

  2. Adverse effect

    Time frame: 12 weeks

    adverse effects were measured by Epithelization Scale. ES is the total sum of evaluation of three components after wounding. please refer this article Min et al, Wound Repair and Regen, 2014;22(2):212-9
