The Sneaky Way Halloween Is Ruining Your Skin — and What to Do About It

Slurp down an espresso cocktail come All Hallows' Eve and you're all but asking for next-day hangover face. "Caffeine causes your blood vessels to constrict, which prevents them from pumping the necessary amount of antioxidants and nutrients through the body," Dr. Jaliman said. That means you're likely to end up with dull, lackluster skin.

The jolt can also impact your beauty sleep, which does no favors for your visage, either. "It may keep you up at night, interfering with normal sleep patterns," Dr. Zeichner said. "If you don't get a full night's rest, the skin may not be prepared to protect itself from the environment the next day and be left dry and inflamed." Take on the next day with vigor and the antioxidant-packed Peter Thomas Roth Potent-C Power Serum ($95) — hangover face be damned.
