9- Iced coffee
Drinking a caffeinated beverage out of a straw—how most of us down our daily iced coffee—is a skin-aging double-whammy. During the day, we’re exposed to skin-stressors like UV rays, but while we sleep our cells repair themselves. However, downing too much caffeine can interfere with sleep quality, cutting into this rejuvenation time and prematurely aging the skin. What’s more, researchers have found that repetitive facial movements, like sipping through a straw, can cause fine lines and wrinkles.
