How To Hydrate Skin: 13 Derm-Approved Tips To Keep Skin Moisturized

This could probably go without saying, but I'll cover my bases while we're here: You need to moisturize your skin. Without proper hydration, your dermis can become dull, itchy, tight, and inflamed.

Long term, this has less than ideal consequences: Improper hydration can lead to premature aging, developing things like sagging and wrinkles. But it's more than that, too: Moisture plays a vital role in barrier function, one of the organ's most important duties—without it, your skin isn't as protected from external aggressors.

One reason your skin may be feeling dry is because your cleanser is too stripping of your natural oils. It's natural to want an effective cleanser to help you remove makeup, excess oil, or daily debris, but often we can go a bit overboard—the result is dried-out skin post-wash. 

Instead, opt for gentle washes that protect your barrier while helping remove particulate matter at the end of the day. If you have really dry skin, you may even consider skipping a wash entirely come morning (this is totally fine, and you can just splash your face with water before applying your daily lotions and tonics). 

However, you should never skip the night rinse: You need to wash your face so gunk doesn't sit in your pores causing free radical damage.

"Unlike the old-school, alcohol-based toners that could be quite drying to the skin, these days they are more often hydrating formulations," King explains about toners.

These essence options are infused with humectants, oils, and other emollients in order to preserve—and promote—the skin's moisture levels.

Aloe, glycerin, hyaluronic acid, and ceramides are some of the hydrating ingredients found in toners that help to hydrate the skin and keep it quenched. 

We consistently tell you to pat your skin dry post-wash or shower—never scrub or pull.

Now, one reason we say this is because it's never good to tug at the skin.

However, we also say this because it leaves skin just a little damp, which can be the ideal setting for hydrating products (particularly humectants) to layer atop of. 

On that note: Humectant serums make for wonderful layering options for those with chronically dry skin.

By and large, you should think of serums as your treatment step: So whatever skin care goal you are trying to accomplish, focus on that in this layer. This is because serums are formulated with a higher concentration of actives designed to sit atop fresh skin, and in some cases penetrate the stratum corneum.

So for those whose main goal is moisture, you can achieve that by using serums with humectants like hyaluronic acid and glycerin. Humectants are ingredients that attract and hold water in the skin, helping it stay supple throughout the day. 

However, humectants can't do it alone. Emollients are a class of hydrators that work to restore the skin barrier function by soothing the skin and filling in microcracks in the epidermis with lipids.

If you don't think that you need to focus on your barrier health, think again: Chronically dry, inflammation-prone skin is a dead giveaway that you suffer from a compromised skin barrier.

The last step of your moisture-packed layering routine? An oil, which traps in all the hydrators below it. Oils do not have hydrating properties inherently (as they do not contain water), but when used over water-based products, they amplify the other hydrators as they protect them from evaporation.

Hydration comes from the inside out as much as it does the outside in. And there are plenty of supplements formulated to keep your skin hydrated, but perhaps one of our favorites is ceramides.

Ceramides are polar lipids, key lipids that are naturally present in our skin cells2. They make up the barrier between the outside environment and our body, locking in moisture and protecting our skin from damage. If you think of the skin barrier as "bricks and mortar," ceramides are part of the mortar holding it all together—50%, in fact3. They play a huge role in keeping your skin moisturized, glowing, and youthful.

Your skin is more permeable at night, which works in two ways.

First, it means that your skin may lose water more easily, as the moisture in your skin evaporates into the air in a phenomenon called transepidermal water loss. But—and this is the exciting part—it also means that actives can penetrate the skin easier, wiggling into the epidermis to do their work. 

This is why, among other reasons, derms encourage people to use their most potent actives at night.

Using hot water—as in steamy showers and the like—has the incredible ability to strip skin of its natural oils and lipids, thereby stealing from the skin its natural defense system.

Many derms swear humidifiers are their secret weapon for dealing with dry skin. These little household tools disperse water back into the air—closer to the ideal indoor humidity range of about 40 to 50% (this number can easily fall below 30% during the winter—yikes!)

If your dryness issues aren't always of the chronic kind—and thus you're not interested in reinventing the routine wheel—you can toss together some perfectly good DIY hydrators right from your kitchen staples.

Skin feeling a little tight at the moment? Don't worry; these aloe vera masks will soothe them ASAP. Need to soothe and balance irritated skin? This yogurt and honey option will do the trick. Or just looking to infuse skin with some fatty acids and antioxidants? An avocado mask is ideal. 

If you want moisturized, plump skin, you should be mindful that you are eating water-dense, high-fat, antioxidant-rich, hydrating foods known for their complexion-changing properties.

These, it turns out, are actually easy to come by—many might already be in our diet (things like leafy greens and vibrant fruits). But if you are feeling a bit on the drier side of late, consider upping your intake.
