DESPITE the passage of time, a grandmother's skin remained as smooth as a baby's for one big reason.
While her drastic approach is not recommended, there is an important takeaway about what causes the skin to age.
Redditor shared how her grandma's particular fear led to her never having to deal with fine lines.

"So basically SPF - not saying don’t enjoy the sun because it has so many benefits obviously!" she said.
