About this trial

This is an interventional treatment trial for Acne focused on measuring acne, acne scar, microneedling radiofrequency, bipolar radiofrequency

Eligibility Criteria

19 Years - 40 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • moderate acne scar
  • mild to moderate acne lesions

Exclusion Criteria:

  • taking acne medication oral drugs within 2 months topical drugs within 2 weeks
  • taken anu procedures for acne scar within 6 months
  • taking steroid,nonsteroidal antiinflammtory drugs, isotretinoin
  • underlying diabetes mellitus, keloid, or any malignancy

Sites / Locations

  • Department of Dermatology, Seoul National University College of Medicine

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

microneedling radiofrequency device

bipolar radiofrequency device

Arm Description

microneedling radiofrequency

bipolar radiofrequency treatment

Outcomes

Primary Outcome Measures

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

Secondary Outcome Measures

ECCA
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
Adverse effect
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

Intervention Type
Device
Intervention Name(s)
microneedling radiofrequency device
Other Intervention Name(s)
INFINI(Lutronics, Goyang, Korea)
Intervention Description
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.
Intervention Type
Device
Intervention Name(s)
bipolar radiofrequency
Other Intervention Name(s)
Polaris(syneron, israel)
Intervention Description
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.
