Can coffee cause you to look older than you are?( can it cause aging?)

I don't think so. : I think the article (see Springer.com link with same name) "Coffee, but not caffeine, has positive effects on cognition and psychomotor behavior in aging" suggests to me that if coffee helps you function better as you age, you should also look better, more vigorous. Many who drink coffee also smoke, which ages the skin. I would still limit to 2 cups daily. Hopes that helps.
