Subconsciously humans make decisions based on the appearance
of someone else’s face. This could be reading the body language to see if one
will have a peaceful or aggressive encounter. Also, if someone is physically
attracted to another all occurs subconsciously. In recent studies, scientists
have discovered a gene that affects aging in human faces.
Aging cannot be explained on a single gene. However, the
discovery of this gene will open the doors to new research. The researchers of
Manfred Kayser Erasmus Medical Center studied more than 8,000,000 DNA variants.
Through previous studies, the researchers identified a correlation between “how
old” one appears to their relative health. As a result, the researchers used
genome data of 2,600 adults and found a gene that affects facial age call MC1R.
People who had a particular variation of MC1R appeared to be
two years younger than their actual age. This was independent of chronological
age, sex and the amount of wrinkles. MC1R codes for the production of melanocortin
1, which plays a key role in the coloration of skin, hair, and eyes. A
reduction of MC1R increases the chances for skin cancer. Currently, researchers are unaware how the
variation in MC1R causes a more youthful appearance, as more research is required.

It's pretty interesting that the variation of MC1R would be so specific as to say being two years younger than the actual age.
ReplyDeleteI do know there are many factors that go into the age someone appears to be, such as lifestyle choices, but it is surprising that some genes can be produced to help you retain a more youthful appearance. I'm sure these can possibly lead to some new cosmetic practices in the future.
