Anecdotally, it's easy to look at a long-term, heavy drinker and see that it takes its toll. In small amounts, like a drink a day, alcohol can actually benefit your body. Any more than that, and you're just getting older faster. Dr. Oz says too much alcohol can cause "premature wrinkles, loss of collagen, elasticity, redness, dehydration, and puffiness." Alcohol also lowers the levels of Vitamin A in your body, which is an important antioxidant.
