Three-Dimensional Photogrammetric Study on Age-Related Facial Characteristics in Korean Females

Area of Science:

• Aesthetics and Anti-aging Research
• Anthropometry and Biomechanics
• Plastic Surgery and Dermatology

Background:

• Understanding age-related facial soft tissue changes is crucial for effective rejuvenation procedures.
• Three-dimensional (3D) photogrammetry offers a reliable and non-invasive method for anthropometric assessment of facial soft tissue.

Purpose of the Study:

• To investigate age-related facial soft tissue morphology in Korean adult females.
• To utilize non-invasive 3D photogrammetry for detailed facial analysis across different age groups.

Main Methods:

• 192 Korean females were categorized into three age groups: 20-39 (younger), 40-59 (middle), and 60-79 (older).
• Thirty-six facial landmarks were identified using 3D photogrammetric scanning.
• Forty-one facial dimensions were analyzed to determine age-related differences.

Main Results:

• Older women exhibited smaller upper facial volume and height, a narrowed palpebral fissure, elongated upper eyelid height, and a widened nose compared to younger women.
• Significant changes in the lower face included a longer lower facial height, longer and wider philtrum, shorter lower vermilion height, wider mouth, and smaller lower vermilion angle in older participants.
• Facial angles showed greater nasofrontal, nasomental, and labiomental angles, alongside a smaller nasofacial angle in the older group.

Conclusions:

• The study identified specific age-related facial morphological characteristics in the Korean female population.
• These findings provide valuable insights for clinicians performing facial rejuvenation procedures.
