Don't Panic: 10 Solutions for the Most Common Skin Emergencies

Sometimes it’s allergies, but lack of sleep mixed with salty, dehydrating foods and/or alcohol can also cause all sorts of problems the next day: fluid retention under the eyes possibly mixed with dilated blood vessels can make for undereye bags and dark circles. It’s not good, but it can be resolved.

Taking an allergy medication like Zyrtec the night before can help with so-called “allergy eyes,” but in all these cases, Levin recommends throwing some hydration at the problem in the way of a super-moisturizing eye cream to handle your undereye problem — and there’s a particular solution for those dark circles. “Caffeine is one of my favorite ingredients in eye creams that helps constrict blood vessels so you don’t have that swelling underneath the eyes,” Levin says. IT Cosmetics Bye Bye Under Eye Eye Cream, $48, is a great solution.
