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

As if guzzling down drinks with names like Bloody Shirley Temple and Witches Brew weren't scary enough, drinking all that sugar may actually be aging you. Sugar glycates the collagen, Dr. Jaliman said, which weakens the skin's surface and makes it more susceptible to fine lines and wrinkles.

To keep yours from slowing down, look for collagen-revving ingredients like retinol, which you can find in Elizabeth Arden's Retinol Ceramide Capsules Night Serum ($84). (Halloween ballers on a budget, we've got you: Pixi's brand-new Retinol Tonic [$15] is also a great, and affordable, option.)

There's nothing like a salty rim to take the edge off of a too-sweet Halloween drink (pumpkin-inspired margaritas, anyone?), but all that sodium can put a damper on your visage. "Salt, like alcohol, dehydrates the body and pulls water out of your skin," Dr. Jaliman said. "This causes bloating."

So, while you could ask the bartender to kick the stuff from your cocktail, you could also set a reminder on your phone to load up on the soothing Talika Eye Therapy Patches ($49) tomorrow, which can help calm and deflate swollen, puffy skin around the eyes.

We know, we know: it's far more fun to believe red wine is good for you, no matter how (or how often) you drink it. But the truth is that too much of a good thing can lead to dehydration and skin inflammation. "Red wine is also known to be a common trigger for rosacea, so try to avoid it if you suffer from this condition," Dr. Zeichner said. Just as spooky: every time you imbibe, you're also causing the blood vessels in your face to dilate, which can lead to some serious redness.

Luckily, this Skinceuticals Phyto Corrective Masque ($58) exists; the formula is loaded with anti-inflammatory botanicals and hydrating hyaluronic acid to give your skin instant relief, every single time.

Kit Kats, M&M's, Snickers — chocolate was practically made for Halloween season, and cocktails (or, as some people like to call it, candy for grown-ups) are by no means excluded. However, when you're drinking your spiked hot cocoa, just remember: "Those high sugar levels, whether it is from the candy you eat or chocolaty drinks, can promote inflammation in the skin and may be associated with acne breakouts," Dr. Zeichner said.

Your best next-day defense plan: the Glossier Solution ($24), a chemical exfoliator that unclogs pores and keeps skin in the clear.

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.
