Quantified Evaluation of Whole Face 8-points Supra-periosteum High Molecular Weight Hyaluronic Acid Injection in Asian

Facial aging is a complex process characterized by skin atrophy, subcutaneous fat loss, and alterations in bone structure. The loss of volume, primarily due to bone resorption and loss of adjacent fat volume from different facial regions, leads to soft tissue flattening. Hyaluronic acid (HA) is a widely used biomaterial in clinical practice, known for its excellent tissue compatibility, low risk, and safety. Previous research and clinical practice have demonstrated that HA for facial lifting can help restore facial fullness, elasticity, and promote a more youthful appearance. Dermatologist previously utilized the supra-periosteum lift technique in high molecular weight hyaluronic acid injection. It was found that the material properties of high molecular weight hyaluronic acid not only made it suitable for filling but also provided lifting support, resulting in improvements in cheek fullness and facial aging. However, there has been no detailed quantitative study on the efficacy of high molecular weight hyaluronic acid for facial lifting.

To further investigate this effect, the investigators plan to conduct a prospective, open-label clinical trial. The investigators will recruit 25 adult and use an 8-point supra-periosteum facial lifting technique to inject high molecular weight hyaluronic acid. Assessments will be conducted preoperatively, postoperatively, and 4 weeks, 12 weeks and 24 weeks postoperatively to analyze the treatment efficacy. The eight injection points will be located at the brow peak, brow tail, pterion, lateral canthus, zygomatic ligament, mid-cheek, nasolabial fold, and mentalis. The investigators will use evaluation forms with four angles and six lengths, as well as the Global Aesthetic Improvement Scale, to quantify the degree of improvement in facial aging. Additionally, The investigators will use a satisfaction survey to understand subjects' perceptions of postoperative lifting effects and overall improvement satisfaction. The investigators hypothesized this study to improve facial aging in Asian patients and provide long-lasting effects.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Eyebrow Peak angle	The vertices of the Eyebrow Peak angles lie at the static point eyebrow head, measured against a horizontal line parallel to the ground.	At Week 4, 12, and 24
Eyebrow Tail angle	The vertices of the Eyebrow Tail angles lie at the static point eyebrow head, measured against a horizontal line parallel to the ground.	At Week 4, 12, and 24
Pupil-Eyebrow Peak angle	The Pupil-Eyebrow Peak angle is then measured between this line and another line connecting nasal to eyebrow peak.	At Week 4, 12, and 24
Canthus-Oral-Nasal angle	The Canthus-Oral-Nasal angle is measured between a line connecting oral commissure to nasal and a line connecting oral commissure to lateral canthus.	At Week 4, 12, and 24
Eyebrow-Orbital length	The linear distances from point superior orbital rim to the inferior border of eyebrow.	At Week 4, 12, and 24
Orbital-Upper Eyelid length	The linear distances from point superior orbital rim to the superior border of palpebral fissure.	At Week 4, 12, and 24
Vertical Palpebral Fissure length	The size of the palpebral fissure can be determined by measuring the vertical distance between the superior and inferior borders of palpebral fissure when the eyes are at rest.	At Week 4, 12, and 24
Eyebrow-Iris length	The horizontal distance between the lateral limbus of the iris and the eyebrow peak .	At Week 4, 12, and 24
Tragus-Oral length	The distances between the bilateral tragi passing through the oral commissure.	At Week 4, 12, and 24
Lower Facial Contouring length	The distances between the bilateral tragi passing through the mental protuberance.	At Week 4, 12, and 24
Antiaging Scales for facial rejuvenation	Index 5 is identified as "neutral" or "no significant changes". Total score for the whole face was 100; either lower or higher than 50 suggesting "aging" or "rejuvenation, respectively". °: degree; mm: millimeter.	At Week 4, 12, and 24

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Global Aesthetic Improvement Scale	Subjects with Global Aesthetic Improvement Scale (GAIS) from baseline after injection will be evaluated by a subjects who will judge the severity score. Score 0 (worse)~4 (Very much improved)	At Week 4, 12, and 24
