The most effective way to help dry skin is to restore moisture and then lock it in. That means using the right moisturizer, adjusting how you bathe, and paying attention to your environment. Dry skin happens when the outer layer of skin loses water faster than it can be replenished, and the fix involves addressing both sides of that equation.
How Moisturizers Actually Work
Not all moisturizers do the same thing. The ingredients fall into three categories, and the best products combine all three.
Humectants attract and bind water. Glycerin, hyaluronic acid, and urea are common examples. They pull moisture from deeper layers of skin toward the surface. One important caveat: humectants used alone can actually increase water loss through the skin, making dryness worse. They work best when paired with an ingredient that seals that moisture in.
Occlusives form a physical barrier on the skin that prevents water from evaporating. Petrolatum is the gold standard here, reducing water loss through the skin by nearly 99%. Other options include mineral oil, dimethicone (a silicone), beeswax, and plant oils like coconut or jojoba oil. If your skin is very dry, an occlusive layer is the single most important thing you can add.
Emollients fill in the tiny gaps between skin cells, making skin feel smoother and softer. Shea butter and ceramides fall into this category. They don’t just improve how skin feels; they help repair the physical structure of the skin barrier itself.
Why Ceramides Matter
Ceramides are the most important class of fat in your skin’s outer layer, making up roughly 50% of the lipid barrier by mass. When ceramide levels drop, the barrier develops gaps, and water escapes more quickly. This is the core mechanism behind most dry skin.
Moisturizers containing ceramides help replace those missing fats directly. They’re particularly useful for people with chronically dry or eczema-prone skin. When shopping for a moisturizer, ceramides on the ingredient list are a strong signal that the product is designed to do more than just sit on top of your skin.
Urea for Stubborn Dry Skin
Urea is a naturally occurring molecule in your skin that pulls in and holds water. In moisturizer form, it’s one of the most effective ingredients for persistent dryness. Concentrations of 5% to 10% consistently improve skin hydration in clinical studies, with both strengths producing similar results over six weeks of use. Many people find the 5% formulation more pleasant to wear.
At 10% and above, urea also works as a gentle exfoliant, breaking apart the bonds in dry, flaky skin to help it shed. For very thick, dry skin on the feet or heels, concentrations of 20% to 40% can soften rough patches more effectively than petrolatum alone. One thing to watch: urea can sting on cracked or irritated skin. About 24% of people in one study reported a smarting sensation when applying a 4% urea cream to sensitive areas, compared with only 10% using a glycerin-based product.
The Right Way to Shower
Hot water is one of the most common causes of dry skin that people overlook. Research comparing hot and cold water exposure found that hot water more than doubled water loss through the skin and significantly increased redness. Even lukewarm water increases some water loss, but far less than hot.
Keep showers to five to ten minutes using warm (not hot) water. Close the bathroom door to trap steam, which adds humidity. Pat your skin dry with a towel rather than rubbing, and apply moisturizer immediately while your skin is still damp. This traps a thin layer of water against the skin before it evaporates.
Choose the Right Cleanser
Harsh detergents strip the oils that keep your skin barrier intact. Use a gentle, fragrance-free cleanser, and only apply it where you actually need it: armpits, groin, and anywhere visibly dirty. The rest of your body does fine with water alone. Skip the thick lather; if your cleanser foams heavily, you’re likely using more than necessary.
A note on “unscented” versus “fragrance-free”: these are not the same thing. Unscented products can still contain chemicals that mask other ingredients’ odors, and those chemicals can irritate dry skin. Look specifically for “fragrance-free” on the label.
Ingredients That Make Dryness Worse
Fragrance is the most common irritant in skin care products for people with dry skin. Retinoids, while useful for anti-aging, increase skin cell turnover in a way that can worsen dryness, especially during the first weeks of use. If your skin is already dry and irritated, consider pausing retinoid products until the barrier heals.
Alcohol in skin care has a more nuanced reputation than most people expect. Alcohol-based hand sanitizers actually cause less skin irritation than washing with soap and water, and may even have a mild protective effect when used after hand washing. The bigger concern is denatured alcohol (often listed as “alcohol denat.”) in leave-on products like toners, which can decrease skin hydration over time.
Cream and Ointment vs. Lotion
Ointments and creams deliver more moisture than lotions. Lotions have a higher water content, which means they feel lighter but evaporate faster and provide less of an occlusive barrier. If your skin is mildly dry, a cream may be enough. For moderate to severe dryness, an ointment containing petrolatum or dimethicone will do more.
Apply moisturizer several times throughout the day, not just after showering. Reapply after washing your hands, and keep a tube at your desk or in your bag so you can address dryness before it worsens.
Indoor Humidity and Environment
Dry indoor air pulls moisture from your skin constantly. Heated air in winter and air conditioning in summer both lower humidity. The optimal indoor range for skin and overall health is 40% to 60% relative humidity. A simple hygrometer (available for a few dollars) can tell you where your home stands.
If your home falls below 40%, a humidifier in your bedroom makes a measurable difference. Run it while you sleep and clean it regularly to prevent mold. During cold months, wearing gloves outdoors protects the thin skin on your hands from wind and low humidity, which are two of the fastest ways to dry out already vulnerable skin.
What You Eat Can Help
Your skin’s lipid barrier depends partly on the fats you consume. Omega-3 fatty acids, found in fatty fish, walnuts, and flaxseed, influence ceramide production in the skin and reduce inflammation that can weaken the barrier. A higher ratio of omega-3 to omega-6 fats in your diet appears to support better barrier function.
Gamma-linolenic acid, an omega-6 fat found in evening primrose oil and borage oil, is one notable exception to the general recommendation to favor omega-3s. Its metabolites have anti-inflammatory properties and are linked to increased ceramide production. For most people, eating fatty fish two to three times a week and reducing processed seed oils provides a reasonable dietary foundation for healthier skin.
Why Skin Gets Drier With Age
Dry skin becomes significantly more common after age 60. The skin produces fewer natural oils over time, particularly in areas with fewer oil glands: the lower legs, forearms, hands, and feet. The lipid barrier thins, ceramide levels decline, and the skin holds less water. This is why someone who never needed heavy moisturizer in their 30s may find their skin cracking and flaking in their 60s.
The approach doesn’t change with age, but the intensity should. Older skin benefits from richer ointments rather than light lotions, shorter showers at cooler temperatures, and consistent daily moisturizing rather than occasional application. Urea-based creams at 5% to 10% are particularly well suited to aging skin because they both hydrate and gently remove the buildup of dry, rough cells.
