The researchers stated that a particular gene allowed people to look up to 10 years younger than their actual age
Singapore: Scientists from Harvard University and a private genetic company, 23andMe, have studied 1 million people and found that 10 percent of white and 20 percent of black Americans carried the "genetic recipe" for younger looking skin.
According to the researchers, the genes fitted into seven categories that are affected by the several areas such as DNA repair, the junctions' maintenance between the skin cells and, the performance of the skin's barrier against damaging the factors of environment.
The elements produced in the skin has another category called lamellar bodies, which contain lipids production, molecules such as fats, waxes and nutrients that would help to keep the skin moist.
"Many of us felt that people with darker skin aged better because of more pigment in their skin and better sunlight protection, but we have found that there was much more to it than what it had," said Dr Alexa Kimball, a lead researcher and professor of dermatology, Harvard Medical School. However, the study has given a new insight into the science of ageing and revealed other characteristics in the skin.
