Science discovers why some adults look younger despite their age

toGenetics is the study of genes and how certain traits are passed from one generation to the next. According to the National Human Genome Research Institute in the United States, it includes DNA variation, its interactions with environmental factors, and the reason behind physical appearance.

newly, A study from the Central Medical University of Rotterdam has found the reason why some people look much younger than they actually are.

The research was published in the scientific journal “Current Biology” and was organized by the Erasmus University Medical Center in the Netherlands and Unilever. The methodology consisted of: Analyze 2,693 photos of older people and ask a group of people how old they think they were. A comparison was then made with biological age.

The sample consisted of people who had mutations or variations in their genes. When analyzing the results, they found this The common denominator was the MC1R gene.

in the middle, Participants said people looked two years younger. They will have some variations in the gene. However, the researchers determined that those who were homozygous for this gene looked two years older.

According to the Medline Plus website. Mutations in this part of DNA are associated with red hair, pale skin, and frecklesBecause it plays an important role in normal pigmentation.

Pale skin increases susceptibility to sun damage and wrinkles. But in the study published in the journal “Current Biology”, Scientists say the gene's effect remained even when they excluded skin colour, wrinkles and exposure to sunlight.“, explains an article in The Guardian.

Joao Pedro de Magalhaes, who studies the genetics of aging at the University of Liverpool, said the study was interesting. “MC1R has been genetically linked to UV-induced skin damage and skin characteristics, such as pigmentation, freckles and age spots. Therefore, Perhaps not surprisingly, this gene plays a role in age perception.He said in an interview with British media.

But scientists explain this More research is still needed on this topic to determine the true impact of this gene on younger physical appearance.

next to, There may be other factors and reasons why a person appears younger or older. Among them, sociocultural perception, tobacco consumption, and exposure to ultraviolet sunlight stand out.
