Dynamic Periocular Wrinkle Patterns: An Anatomical Study on Young Adults

Area of Science:

• Dermatology
• Aesthetics
• Aging Research

Background:

• Aging leads to facial wrinkles, particularly dynamic wrinkles from mimic movements.
• Periorbital areas are prone to early static wrinkle development.
• Understanding dynamic wrinkle precursors is key to early intervention.

Purpose of the Study:

• To analyze dynamic wrinkle patterns in the periorbital skin of healthy young adults.
• To identify specific wrinkle precursor regions during mimic movements.
• To establish a new classification for periorbital dynamic wrinkles.

Main Methods:

• Analysis of dynamic periorbital wrinkle patterns in 184 healthy adults (18-24 years).
• Standardized facial photography at rest and during mimic movements.
• Classification and analysis of wrinkles in superior, inferior, lateral, and medial periorbital subregions.

Main Results:

• Distinct wrinkle patterns identified in superior (oblique lines), inferior (linear wave), and lateral (radial waves) periorbital regions.
• Medial periorbital region showed less specific patterns, with prevalence of Type 6 (no specific pattern) and Type 2 (arrowhead-like).
• Significant sex differences observed: absence of distinct medial patterns more common in males; miniature crow's feet-like wrinkles more common in females.

Conclusions:

• A novel classification of dynamic periorbital wrinkle patterns in young adults is presented.
• The study highlights significant sex-based variations in periorbital wrinkle formation.
• Findings provide insights into early wrinkle development and potential sex-specific preventative strategies.
