Beauty Byte: Sun Exposure Causes Increased Genetic Mutations

Do you ever wonder why some people seem to age at a rapid pace, while others look years younger than what their birth certificate might suggest? That's just what P&G Beauty scientists recently sought to discover, using genomics to learn more about the aging of skin.

While lower levels of collagen, increased inflammation, and a decrease in hydration-enhancing molecules in the skin all contribute to aging, there's one other factor that might surprise you. You know that sun isn't great for your skin, but as it turns out, it's really not great for your skin. Shockingly, skin that had not been exposed to the sun had around 3,000 genetic mutations, but skin with exposure had — are you ready for this? — nearly 10,000 genetic mutations. So if that's not another reason for you to run and grab the sunscreen, I don't know what is.

I grew up near a beach and I could kick myself for not wearing sunscreen as a teenager! At least I changed my habits in my early 20s.

That is exactly why skin cancer is carcinogenic. Although the exact numbers may be novel, this isn't even remotely new information.
