About 15 years ago scientists made a stunning discovery: There are genes that control aging. This was followed by another significant finding: These genes, called sirtuins, could be activated to extend life span—a phenomenon that has since been proven in yeast, fruit flies, a tiny worm and mice. What’s more, the animals in these studies didn’t just go on to live longer lives, they went on to live healthier lives, with less diabetes, less weight gain on high lipid diets and better allover cardiovascular well-being.
While life-span extension hasn’t yet been achieved in humans, it’s being studied at the cellular level with promising results. The implications for a longer, healthier life are clear. Such research has equally as significant consequences for the beauty industry. As the science of aging has progressed, cosmetics firms have benefited with an increasingly deeper understanding of how the skin ages and have been able to harness that information to develop ever more sophisticated products.

"That's something that resonates with me too because I'm so locked into a number. If I go over that number it completely ruins my day so it's nice to get detached from the number on the scale." - Chelsea Handler on Kelly LeVeque's book "Body Love." #wwdeye (📷: John Salangsang)
