| 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. |
| Measure | Description | Time Frame |
|---|---|---|
| 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 |
| Measure | Description | Time Frame |
|---|---|---|
| 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 | 12 weeks |
