Caffeine is known to cause acne breakouts. Also, excess intake of it can lead to dehydration. You would certainly not want to faint on the stage or want a pimple because of consuming several cups of coffee, right? So, try swapping your cup of cappuccino with herbal tea or natural fruit juices. If you cannot survive without your morning cup of coffee, then opting for a decaffeinated one is a better idea.
