Facial Subcutaneous Fat

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.
