If you've ever run a long distance, taken an intense hot yoga class, come down with the flu, or, ahem, woken up with a hangover, you've likely reached for an electrolyte drink. That's because the electrolytes in that bottle of Gatorade can supply your body with essential minerals that retain water and rehydrate you.

Now, imagine if there was a hydrating helper like that but for your skin! Pipe dream? Nope—very much a reality. Introducing electrolyte skin care, the newest beauty trend that's all about applying electrolytes topically to reap similar benefits for your skin. (Related: What's the Deal with Performance Water?)

First, a quick refresher (pun intended) on electrolytes.

All electrolytes, whether from coconut water or coconut water-based moisturizer, work the same. Electrolytes—including magnesium, calcium, potassium, sodium, chloride, and phosphate—conduct electricity when mixed with water, says Peterson Pierre, M.D., a dermatologist at Pierre Skin Institute in Thousand Oaks, California. If you're thinking electricity in the body sounds futuristic (or dangerous), have no fear. Electrical currents are naturally present in the body and electrolytes are essential to the functions of cells and organs.

When consumed, "electrolytes help you retain fluid and also increase thirst, so you keep drinking," Melissa Majumdar, R.D., a bariatric dietitian for the Brigham and Women's Center for Metabolic and Bariatric Surgery previously told Shape.

Okay, but what about electrolytes in your skin care?

Because water follows the flow of electrolytes, using electrolyte-infused skincare would allow water to be drawn into the skin thereby increasing the skin's hydration status, explains Dr. Pierre. (Psst...did you know that there's a difference between hydrating and moisturizing products?!)

Electrolytes are best for dry skin types or skin that needs more hydration since, again, electrolytes drive more water into the skin to be absorbed, says Nazanin Saedi, M.D., director of Jefferson Laser Surgery and Cosmetic Dermatology Center. Electrolytes can also give skin a boost to look more buoyant, plump, and healthy.

What's more, electrolyte skin care can not only increase the moisture content in the skin but can also allow other ingredients (vitamins or ceramides, for example) in the products you're currently using to perform even better, says Dr. Pierre. Think of it this way: If your skin is a road and skin care products are a car, then electrolytes are the gas. Electrolytes give energy to other ingredients to power them into your skin cells.

While, the jury is still out on just how much water is actually drawn into the skin with these electrolyte-based products, there's certainly no harm in testing them out. As with any skin-care routine or new product, consistency is key when it comes to seeing results. "If a patient and I see an improvement when they're using an electrolyte skin-care product, I would encourage them to continue with it," says Rita Linkner, M.D., a dermatologist at Spring Street Dermatology in New York City.

Since electrolytes work with water, you'll find that most formulas in this category are moisturizers or hydrating masks. Now, check out these top 10 products to buy if you're skin needs a drink.
