Beauty myths

Myth #1: You should wash your face in the shower

This is most definitely not the case, unless you also apply your toner and moisturizer under the shower head (which we obviously wouldn't recommend). “As soon as you’re done cleansing, you want to immediately move on to the next step in your skin-care routine,” explains therapeutic skin coach Hayley Roy. Washing your face in the shower could actually cause acne, due to its impact on your skin's pH. Who knew, right?

Beauty myths

Myth #2: Less is more when it comes to moisturizer

Wrong again. The more hydration, the better—and two layers are, in fact, superior to one. “The idea is that you’re doing two stages of moisturizing to pack in the hydration,” dermatologist Dhaval Bhanusali, MD, of Sadick Dermatology explains of the Korean beauty-inspired double moisturizer trend. (No, it's not just a marketing ploy to get you to buy more products.) So if you're applying your favorite facial oil sparingly, you may want to lean towards the generous end of the spectrum.

Beauty myths

Myth #3: You can use dry shampoo with abandon

Actually, you should be aiming to spritz your strands no more than twice a week. “For some, [dry shampoo] can create irritation, or inflammation of the hair follicles," says dermatologist Mona Gohara, MD. The magic grease eliminator can also be seriously dehydrating for your hair, so save it for after those super sweaty workouts that leave you and your 'do drenched.

Beauty myths

Myth #4: Caffeine is bad for your skin

When sleep slips down the priority list, everyone's favorite pick-me-up helps in more ways than one—it also banishes dark under-eye circles.“Caffeine functions as a vasoconstrictor—or a tightening agent—that constricts the blood vessels around the eye area, which in turn makes the dark circles and puffiness less visible,” explains Lauren Hoffman, whose beauty brand Onomie focuses on the eyes. Of course, it's  not as simple as ordering a double; caffeine needs to be applied topically in order to give your skin a boost.

Beauty myths

Myth #5: Beer is the enemy of beauty

It may not be great for your belly, but beer is good for another part of your body: your hair! Turns out that malted barley is full of nutrients that are released during the brewing process, like B12 and folate, which support healthy hair follicles and growth. (You can even find brew in shampoo now.) The best part? In place of a next-day hangover, you'll just have Kate Middleton-esque locks.

Beauty myths

Myth #6: You should always wash your face in the a.m.

Don't stress if you run out of time to cleanse before rushing out the door. It's more important that you wash your face at night to get rid of unwanted oils and dirt that may build up throughout the day. “Unless you’re doing something insane while you’re sleeping, you really don’t need to get in there and use a high-powered cleanser in the morning,” says Rachel Winard, founder of natural beauty brand Soapwalla. She recommends sticking to just a toner (before applying your usual moisturizing creams or oils) just after waking up.

Beauty myths

Myth #7: The only way to get a collagen boost is with the help of needles

In fact, drinkable collagen is gaining ground in wellness circlesJennifer Aniston included—and it might be more effective in boosting skin suppleness than other methods. “When you ingest science-based hydrolyzed collagen, you increase the pool of special amino acids available to the cells in your body that make it,” explains Naomi Whittel, founder and CEO of nutritional supplement company Reserveage. In layman's terms, that means consuming collagen nudges your body into making more of it naturally—we'll take that over injections any day.

What you eat affects your skin, too. The main culprit: sugar. But that doesn't mean you have to say goodbye to dessert just yet. Try one of these low sugar dessert recipes when your sweet tooth starts talking, or if you do overindulge, load up on this nutrient to help offset the effects.
