You might have heard that your nose and ears keep growing your whole life, but it's actually more like they're getting stretchier. It's sort of true. Like, a study in the UK found that people's ears got about .22 millimeters longer per year of life. And similar conclusions were found in Japan. So, in a sense, yeah, they're taking up more real estate on your face, but it's not because they're growing. One idea of why they might look like that involves collagen, which your nose and ears are made of, getting broken down as you age. UV exposure from the sun can also speed that up. So, they aren't as sturdy as they used to be, and gravity stretches them out over time. On top of that, you make less collagen as you age. So not only is your current collagen getting broken down, you're also not replacing it as efficiently. And unfortunately, this happens with or without sunscreen. So, in the end, your ears will hang low. But it's more due to destruction than growth.
