How drinking from a straw can cause fine lines from the dermis
“Reusing straws can cause additional wrinkles,” says Amin. “Over time, these lines will begin to form at rest,” she adds. This means that even if you don’t drink through a straw, fine lines will remain.
These lines are often called “smoker’s lines” because both drinking through a straw and smoking involve constant puckering of the lips, which produces similar effects on the skin. (Though smoking also exposes your skin to free radicals, which can speed up the process even more.)
This doesn’t mean you should never drink from a straw again—sometimes it won’t matter much. But if you’re using a reusable water bottle with a straw all day every day, it might be something to consider.
