Facial Skin Aging: a multidimensional phenotype

The document discussed the multidimensional aspects of facial skin aging, focusing on features such as wrinkles, pigmented spots, and telangiectasia, which contribute to the perceived age of individuals. It explored the role of vitamin D and utilized digital measurement techniques to assess these aging markers. The study also incorporated epidemiological data and genome-wide association studies (GWAS) to understand the genetic factors influencing facial skin aging. This comprehensive approach aimed to provide a deeper understanding of the biological and environmental factors contributing to the aging process of facial skin.
