Research on the Evolution, Geometry, and Alterations of the Periorbital Region Based on Age and Deformations

Research on the Evolution, Geometry, and Alterations of the Periorbital Region Based on Age and Deformations

The periorbital region of the face is a critical area affected by aging. Motion Capture (MoCap) allows the precise measurement of the mechanical properties of skin in this region. This study will validate MoCap as a tool for quantifying these properties, comparing it to traditional reference tools, and exploring how these properties evolve with age and external treatments. It will also assess MoCap's ability to detect the effects of various treatments such as tightening products and massages. Ultimately, this research will provide a deeper understanding of skin dynamics in the periorbital region and offer insights into both medical and cosmetic applications.
