It really varies from person to person. I used to drink it often, but it won't cause acne, but my skin will get worse. If it's for refreshing, it's actually the same as drinking tea. At least better than that. You can drink green tea. And it also helps metabolism, but don't overdo it, whether it's coffee or tea. And staying up late is also the enemy of the skin. Don't just say that it is caused by drinking coffee, but it may also be caused by staying up late.
