Dry skin happens when the outer skin layer loses moisture faster than it can hold it, usually because the air is dry or the skin’s natural barrier is disrupted.
If your skin feels tight, rough, or flakes off, the problem is almost always one thing: water leaving the skin faster than it should. The outer layer of your skin, the stratum corneum, acts as a moisture barrier. When that barrier gets damaged—by weather, washing habits, or age—it can’t hold onto water. Dry indoor air then pulls what little moisture remains right out. The fix isn’t expensive creams; it’s changing a few daily habits and choosing the right cleanser when you wash.
What Actually Causes Dry Skin?
Most dry skin comes from a combination of environmental triggers and how you treat your skin. Cold or windy weather, low humidity, and forced-air heating all pull moisture out of the air and your skin. In the United States, dry skin is especially common during northern winters when indoor heating runs constantly, and in southwestern desert climates where the air itself is bone-dry year-round.
Your daily routine matters just as much. Long hot showers strip the skin’s natural oils. Harsh soaps and deodorant bars do the same. Frequent handwashing, chlorine from swimming pools, and even over-scrubbing with a rough towel all break down the barrier faster than your skin can repair it. If you already have eczema, psoriasis, or diabetes, your skin is more vulnerable to begin with—but even perfectly healthy skin can get dry with the wrong habits.
Who Gets Dry Skin Most Often?
Older adults are far more likely to have dry skin because aging skin produces less sebum, the natural oil that helps seal in moisture. People with certain medical conditions—including eczema, psoriasis, hypothyroidism, kidney failure, and Sjögren’s syndrome—also have a harder time keeping their skin hydrated. Some medications cause dryness as a side effect. And anyone who works with their hands in water, harsh chemicals, or extreme temperatures will notice the effects quickly. Cleveland Clinic notes that xerosis, the medical name for dry skin, is one of the most common dermatology complaints in colder months.
The Right Way to Treat Dry Skin
The American Academy of Dermatology recommends a short, consistent routine that doctors have backed for decades. Limit showers and baths to 10 minutes or less using warm—never hot—water. Use a gentle, fragrance-free cleanser instead of deodorant or antibacterial soaps. After washing, pat your skin dry with a towel; don’t rub. Then apply moisturizer while your skin is still damp, because that traps the water the skin just absorbed. Reapply moisturizer during the day, especially on your hands after every wash.
If your home has dry indoor air—and most heated homes do in winter—a humidifier helps. Protect your skin outdoors with gloves in cold or windy weather, and use a broad-spectrum sunscreen of SPF 30 or higher whenever you’re outside. If you need a cleanser that won’t strip your skin further, our roundup of the best dry skin cleansers for gentle washing covers the options that actually work without damaging the moisture barrier.
What Not to Do (And When to See a Doctor)
Most dry skin mistakes come from thinking more is better. Long hot showers, bathing more than once a day, using deodorant or antibacterial soaps, and scrubbing hard with exfoliating products all make dryness worse. Skipping moisturizer after washing is the single most common error—and the easiest one to fix. The Mayo Clinic advises that dry indoor air from central heating or wood-burning stoves is a major hidden cause that many people ignore.
See a doctor if your skin cracks, bleeds, becomes red and swollen, or hurts. Persistent dryness that doesn’t respond to moisturizing can signal an underlying condition like eczema, psoriasis, or a thyroid problem. Dry skin that becomes infected—look for oozing, crusting, or spreading redness—needs medical treatment. For the vast majority of people, though, shorter showers and a good moisturizer applied to damp skin will solve the problem within a few days.
FAQs
Does drinking more water cure dry skin?
Not by itself. Drinking water keeps your body hydrated internally, but dry skin is a problem of moisture loss from the outer barrier—not dehydration from the inside. You still need to use moisturizer and avoid stripping cleansers even if you drink plenty of water.
Can dry skin turn into eczema?
Severely dry skin can trigger eczema flare-ups in people who are already prone to the condition. The cracked, damaged barrier lets irritants in and moisture out, which can start the inflammation cycle.
Why does my skin get dry only in winter?
Winter air holds less moisture than warm air, and forced-air heating makes that problem worse by further drying the indoor environment. The combination of low outdoor humidity and indoor heating creates ideal conditions for skin to lose water rapidly. Summer humidity usually provides enough environmental moisture to compensate.
