It won't surprise you to learn that alcohol, like many of the other things we love in life, is pretty harsh on the skin. First, drinking basically makes it impossible for your body to stay hydrated. "Alcohol is a diuretic, which means it causes you to pee more," says NYC-based dermatologist Whitney Bowe, MD. "But it also hinders the production of the hormone vasopressin
. That hormone helps you reabsorb water. So alcohol is kind of a double whammy, in that it's forcing out water and
making it harder for your body to rehydrate itself." And we all know what dehydrated skin looks like — tired and sallow, with more pronounced fine lines, wrinkles, and pores.
