简要总结
This is a prospective, single-arm, open-label, pilot clinical study to evaluate the efficacy and safety of overnight occlusive topical application of 10% high-concentration 35 kDa hyaluronan (HA35) gel for facial aesthetic improvement. Eligible participants will receive overnight occlusive application once every 2 days for a total of 5 treatments over 10 days. The primary objectives are to assess changes in facial subcutaneous fat appearance, inflammatory erythema, skin radiance, and nasal alar pore enlargement after 1 and 5 applications. Safety and local tolerability will be evaluated throughout the study period. This is a minimal-risk, non-pharmacological, non-invasive aesthetic intervention.
详细描述
This prospective, single-center, single-arm, open-label pilot clinical study investigates the efficacy and safety of overnight occlusive topical 10% high-concentration 35 kDa hyaluronan (HA35) gel for improving multiple facial aesthetic outcomes, including subcutaneous fat appearance, inflammatory erythema, skin radiance, and nasal alar pore condition.
Eligible subjects will apply HA35 gel to the entire face before sleep, covered with an occlusive film to retain moisture, and left in place overnight. The intervention will be administered once every 2 days for 5 applications over 10 days.
Outcomes will be assessed at baseline, after 1 application, and after 5 applications using a standardized 0-10 Numeric Rating Scale (NRS) for subcutaneous fat thickness, erythema severity, skin radiance, and pore enlargement. Local skin tolerability and adverse events will be monitored throughout the study.
This is a non-invasive, non-pharmacological aesthetic intervention with minimal risk. All procedures are conducted in accordance with the Declaration of Helsinki, and written informed consent is obtained from all subjects prior to enrollment.
