Safety and Efficacy Evaluation of the Radiofrequency Therapeutic Device for the Treatment of Atrophic Acne Scars
A Prospective, Multicenter, Randomized, Parallel-Controlled, Blinded-Assessment, Non-Inferiority Clinical Trial to Evaluate the Safety and Effectiveness of a Radiofrequency Therapeutic Device for the Treatment of Atrophic Acne Scars
The objective of this clinical trial is to evaluate the safety and effectiveness of a radiofrequency treatment device for the treatment of atrophic acne scars.
This is a prospective, multicenter, randomized, parallel-controlled, blinded-assessment, non-inferiority trial design.
The study aims to evaluate the effectiveness and safety of the radiofrequency therapeutic device manufactured by Sponsor for the treatment of atrophic acne scars, in comparison with the control device, the radiofrequency therapeutic device.
Participants will receive treatment sessions using either the investigational device or the control device, undergo follow-up evaluations after treatment to assess efficacy and safety outcomes.
The primary endpoint is Improvement in atrophic acne scars measured by the ECCA score compared with baseline, assessed 12 weeks after the final treatment.
The secondary efficacy endpoints include Global Aesthetic Improvement Scale (GAIS), Study Participant Satisfaction Assessment, Pain Score, Changes in skin characteristics compared with baseline Safety evaluations include Adverse events (AEs), Serious adverse events (SAEs)

Opis
Inclusion Criteria:
- Participants aged 18 to 65 years at the time of written informed consent.
- Participants with Fitzpatrick skin types II to V.
- Participants with facial atrophic acne scars and an ECCA score ≥60 as assessed by the investigator.
- Participants who are able to understand the purpose and procedures of the study, voluntarily agree to participate, and provide written informed consent.
Exclusion Criteria:
- Participants with a history of facial surgery or cosmetic surgical procedures, or those planning to undergo cosmetic surgical treatment during the study period, which in the investigator's judgment may increase treatment risk or affect efficacy evaluation, including any of the following:
- Participants with active or progressive skin diseases in the treatment area, or skin diseases associated with the Koebner phenomenon, such as eczema, psoriasis vulgaris, lichen planus, or vitiligo, which in the investigator's judgment may affect treatment or evaluation.

- Participants with scars, tattoos, piercings, excessive hair, or other conditions in the treatment area that, in the investigator's judgment, may interfere with treatment or evaluation.
- Participants with impaired skin barrier function in the treatment area that, in the investigator's judgment, may increase treatment risk or affect efficacy evaluation.
- Participants with a history of excessive sun exposure within 1 month prior to screening that, in the investigator's judgment, may increase treatment risk or affect efficacy evaluation.
- Participants with known hypersensitivity or allergy to lidocaine, other local anesthetics, or any device or medication components used in this study.
- Participants with severe hepatic or renal dysfunction, serious disease of other major organs, or uncontrolled diabetes mellitus.
- Participants with abnormal coagulation function during screening, use of medications affecting platelet or coagulation function, or platelet count below the lower limit of normal.
- Participants with active autoimmune disease or a history of autoimmune disease, including systemic lupus erythematosus, rheumatoid arthritis, scleroderma, or dermatomyositis.
- Participants with a history of keloid formation.
- Participants diagnosed with psychiatric disorders or active anxiety or depression that may impair the ability to understand or comply with study requirements.
