When your skin is hydrated, everything just feels right. Your skincare absorbs better, your makeup looks better, and there’s a plump, dewy glow that shines through.

So when you have dehydrated, dry skin—whether it’s tight and uncomfortable, or flaky with dead skin cells—you want to fix it fast.

What’s even smarter? Preventing it. Here are four reasons your skin could be dehydrated, plus the face moisturizer to keep you glowing all year long.

Reason #1: Pollution

Your skin is your body’s first line of defense. A strong natural moisture barrier helps keep hydration in and irritants out. When pollution and smog come into contact with skin, they can compromise that barrier and its ability to maintain healthy levels of hydration within, leading to dull, flaky skin. And in a real catch-22, a compromised barrier makes it harder for skin to defend itself against other damaging pollutants—so you can get stuck in a cycle of dehydration.

Reason #2: Blue Light

We are around screens now more than ever—from our cell phones to tablets to computer screens and more. While it’s unrealistic to do away with screen time completely, it’s important to know how it affects our skin. Blue light is made up of the visible waves of light emitted from our screens while we use them, and our daily exposure can create oxidative damage in our skin. This kind of damage also weakens the skin barrier—again, resulting in dry, dehydrated skin.

Reason #3: Air Travel

That uncomfortably tight skin at the end of a long flight? No, you’re not imagining it. The typical airplane cabin is kept at less than 20% humidity—half the recommended levels of your home environment. That means there’s less moisture in the air for skin to draw in and hold onto. Extended time periods at low humidity levels can erode your skin’s moisture stores, leaving you with no glow in sight.

Reason #4: Extreme Weather

You know the term “winter skin?” That dry, dehydrated feeling isn’t just for snow days. Lots of conditions can affect your skin’s moisture barrier, like spring’s blustery winds and the dry heat of summer. And dramatic shifts—like going from an air-conditioned house to a scorching sidewalk to a frigid office—can also stress your moisture barrier and dehydrate skin.
