Here’s a good add I found in a Cosmoplitan article from the April 2010 issue.
Jolt-causing beverages like soda, energy drinks, and coffee constrict your blood vessels, so less fluid flows through your skin-hence, dehydration. Typically, that means a bit more wrinkling at the sides of your eyes and a hollow look underneath them. “The eye area is thin-skinned, so effects are most visible there,” Says dermatologist Ranella Hirsh. (Lips can shrivel too.) As with alcohol, results are worse on an empty stomach, so if you are a fan of red Bull and vodka or venti whatevers, eat a meal before you chug.
I’m a huge fan of coffee so cutting back will be hard. However, getting wrinkles will help me make the right choice and stick with tea.
