Kayser and his colleague David Gunn at the UK- and Netherlands-based company Unilever searched the genomes of more than 2,600 elderly Dutch Europeans from the Rotterdam Study for DNA variants associated with aging features detected on digital images of faces.
They found one gene, MC1R, had a stronger association than any other gene with perceived aging features, such as wrinkling.
This makes sense since the gene, in addition to playing a role in skin and hair color, is also associated with inflammation and DNA damage repair — which can both play a role in age appearance.
Of course, genes aren’t the only thing that contribute to our aging faces. Our environment and lifestyles (i.e. whether we work outside, how often we use sunscreen, etc.) are significant factors as well. But the researchers hope the genetic line of investigation into aging can yield some insight into the process of aging in general.
