If you've ever stared at a picture of Halle Berry and wondered how many SK-II masks it takes for her to look exactly the same as her 25-year-old self, you can stop calculating.

A new study from Harvard University, 23andMe, and Olay has suggested a possible explanation that has to do with genes rather than expensive skin care. A team of Harvard scientists led by professor of dermatology Alexa Kimball analyzed data from over 1 million people (provided by 23andMe) and found that Methuselah genes, or "younger genes" — the ones responsible for characteristics like more-effective DNA repair and the skin's ability to protect against damaging environmental factors (sunlight, etc.) — are found in one-fifth of black Americans, while only one in ten white Americans is a carrier. The presence of these genes allows some people to look ten years younger than their age, according to the paper.
