Again, moderate consumption of alcohol probably won’t age you too much. But alcohol dehydrates you and quickly, which shows up first on your face. Furthermore, alcohol adds lots of calories to your system without concomitant nutrition. If you drink a lot, you will either have to consume excess calories to get nutrition (gaining weight) or you will not consume all the nutrition you need. Poor nutrition shows up in dry skin, which, in turn, leads to wrinkles. An occasional drink is not big deal, but alcohol should not be part of your regular meal plan.
