Efficacy and Safety of High-Dose Oral 35 kDa Hyaluronan for Aesthetic Improvement (HA35-ORAL)

May 7, 2026 updated by: Nakhia Impex LLC

A Prospective, Single-Arm, Open-Label Pilot Clinical Study to Evaluate Efficacy and Safety of High-Dose Oral 35 kDa Hyaluronan (HA35) in Subjects Seeking Facial and Body Aesthetic Improvement

This is a prospective, single-arm, open-label, pilot clinical study to evaluate the efficacy and safety of high-dose oral 70 kDa hyaluronan (HA35) for aesthetic improvement. Eligible participants will receive 5 g oral HA35 once daily on an empty stomach for 40 consecutive days. The primary objectives are to assess changes in facial and body subcutaneous fullness, inflammatory erythema, facial vitality, and body weight. Safety, gastrointestinal tolerability, and additional exploratory outcomes will be evaluated throughout the intervention period. This is a minimal-risk, oral, non-pharmacological supportive care intervention.

Detailed Description

This prospective, single-center, single-arm, open-label pilot clinical study investigates the efficacy and safety of high-dose oral 35 kDa hyaluronan (HA35) for improving facial contour, reducing subcutaneous fullness, alleviating inflammatory erythema, enhancing facial vitality, and supporting body weight management.

Eligible subjects will take 5 g of oral HA35 once daily in the morning on an empty stomach for 40 consecutive days. Outcome assessments will be performed at baseline, Day 7, Day 14, Day 28, and Day 40 using a validated 0-10 Visual Analog Scale (VAS) to evaluate subcutaneous fat reduction, erythema improvement, facial vitality, and gastrointestinal tolerance. Body weight will be measured at each time point.

Safety evaluations include monitoring of adverse events, gastrointestinal comfort, dry eye symptoms, and overall tolerability.

This is a non-invasive, oral, non-pharmacological intervention with minimal risk to participants. All procedures will be conducted in accordance with the Declaration of Helsinki, and written informed consent will be obtained from all subjects prior to enrollment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Facial Subcutaneous Fullness VAS Score (0-10)
Time Frame: Baseline to Day 40
Change in cheek fullness and double chin prominence measured by 0-10 VAS, 0 = no improvement, 10 = maximum improvement.
Baseline to Day 40

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Body Subcutaneous Fullness Severity (0-10 VAS Score)
Time Frame: Baseline to Day 40
Change in body subcutaneous fullness severity, assessed using a 0-10 Visual Analog Scale (VAS), where 0 = no fullness and 10 = maximum perceived subcutaneous fullness.
Baseline to Day 40
Change in Facial Inflammatory Erythema Severity (0-10 VAS Score)
Time Frame: Baseline to Day 7 and Day 40
Change in facial inflammatory erythema severity, assessed using a 0-10 Visual Analog Scale (VAS), where 0 = no erythema and 10 = maximum redness.
Baseline to Day 7 and Day 40
Change in Facial Vitality (0-10 VAS Score)
Time Frame: Baseline to Day 7 and Day 40
Change in perceived facial vitality and skin radiance, assessed using a 0-10 Visual Analog Scale (VAS), where 0 = dull/lifeless and 10 = vibrant/healthy appearance.
Baseline to Day 7 and Day 40
Change in body weight (kg)
Time Frame: Baseline to Day 40
Change in body weight measured in kilograms (kg) using a calibrated digital scale, taken at the same time of day under consistent conditions.
Baseline to Day 40
Incidence and Severity of Treatment-Related Adverse Events
Time Frame: From baseline to the end of the 40-day intervention period
Number and severity of adverse events reported during the study, including gastrointestinal discomfort, allergic reactions, or other systemic effects. Severity is graded using the Common Terminology Criteria for Adverse Events (CTCAE).
From baseline to the end of the 40-day intervention period
Gastrointestinal Tolerability (0-10 VAS Score)
Time Frame: From baseline to the end of the 40-day intervention period
Subject-reported gastrointestinal tolerability, assessed using a 0-10 Visual Analog Scale (VAS), where 0 = no discomfort and 10 = severe gastrointestinal distress (e.g., bloating, nausea).
From baseline to the end of the 40-day intervention period
