The best thing to use on dry skin is a moisturizer that both pulls water into your skin and locks it there. That means looking for products with humectants like glycerin or hyaluronic acid paired with heavier ingredients like petroleum jelly or shea butter that seal moisture in. But the specific product matters less than how and when you apply it, and knowing which ingredients to seek out or avoid can make the difference between temporary relief and skin that actually stays hydrated.
Three Types of Moisturizing Ingredients
Not all moisturizers work the same way. The ingredients fall into three basic categories, and the most effective products combine all three.
Humectants draw water from the air and from deeper layers of your skin up to the surface. Glycerin, hyaluronic acid, and aloe are the most common. They hydrate, but on their own that moisture can evaporate right back off.
Emollients soften and smooth the skin’s surface by filling in tiny gaps between skin cells. Creams, lotions, and ointments are all types of emollients.
Occlusives form a physical barrier on top of your skin that prevents water from escaping. Petroleum jelly, shea butter, and oils like jojoba and grapeseed all serve this function. These are the heavy hitters for seriously dry skin, but they work best when applied over already-hydrated skin rather than on their own.
A good moisturizer layers these functions together: humectants pull water in, emollients smooth the surface, and occlusives trap everything underneath.
Ingredients That Make a Real Difference
If you’re scanning ingredient labels, a few stand out for dry skin.
Ceramides are lipids (fats) that naturally make up about 50% of your skin’s outer barrier by weight. They’re the “mortar” between your skin cells, and when levels drop, moisture escapes more easily. Ceramide-based moisturizers have clinical evidence showing they repair barrier integrity, relieve dry skin, and improve hydration. If your skin is consistently dry rather than just occasionally tight, ceramides are one of the most targeted ingredients you can use.
Hyaluronic acid is a humectant that forms a coating on the skin’s surface, limiting evaporation and improving hydration. Smaller molecules penetrate more deeply: low molecular weight versions (under 100 kDa) reach the deeper skin layers with 63% to 78% efficiency, while larger molecules mostly sit on the surface, with only about 3% to 10% penetrating. Products that list “hydrolyzed hyaluronic acid” or “low molecular weight” hyaluronic acid tend to deliver deeper moisturizing effects, while standard hyaluronic acid works well for surface hydration.
Colloidal oatmeal is an FDA-recognized skin protectant. The starches and beta-glucans in it help your skin retain moisture, and it contains vitamin E, which helps prevent cell damage. It’s a solid option if your dry skin is also itchy or irritated, since it soothes as it hydrates.
Urea is a versatile ingredient that works differently depending on concentration. At 2% to 10%, it acts as a hydrator, drawing moisture into the skin. At 10% to 40%, it becomes an exfoliant that breaks down rough, flaky buildup. For general dry skin on your body, a 5% to 10% urea cream offers hydration with mild smoothing. For thick, cracked skin on heels or elbows, higher concentrations do the heavy lifting.
What to Avoid on Dry Skin
Certain ingredients actively strip moisture or irritate already-compromised skin. Drying alcohols are the biggest culprits. On ingredient labels, watch for alcohol denat., ethanol, SD alcohol 40, isopropyl alcohol, and methanol. These evaporate quickly and pull moisture out with them. They’re common in toners, astringents, and some lightweight lotions.
Fatty alcohols like cetyl alcohol and cetearyl alcohol are a different story entirely. Despite sharing the word “alcohol,” these are actually emollients that soften skin. Don’t avoid those.
Synthetic fragrances are another common trigger. They don’t cause dryness directly, but they irritate sensitive or already-dry skin, which weakens the barrier further and lets more moisture escape. Fragrance-free products are a safer bet when your skin is already struggling.
Face and Body Need Different Products
Body moisturizers are formulated with heavier butters, oils, and film-forming chemicals designed to protect large areas of thicker skin. Facial skin is thinner and more prone to clogged pores. Those heavy body formulas don’t absorb well into facial skin and can cause breakouts or irritation.
For your face, use a lighter moisturizer labeled non-comedogenic (meaning it won’t clog pores). For your body, especially legs, arms, and hands, you can go as heavy as you want. Thick creams and ointments generally outperform thin lotions for body dryness because they contain more occlusive ingredients.
How You Apply Matters as Much as What You Use
The single most effective habit for dry skin is applying moisturizer to damp skin. When your skin is already wet, it’s hydrated. The moisturizer then seals that water in rather than trying to add moisture to a dry surface. If you apply an occlusive product to completely dry skin, it can actually seal moisture out instead of in.
The American Academy of Dermatology recommends applying moisturizer immediately after showering or bathing, while your skin is still damp. Also reapply after washing your hands and anytime your skin feels tight or dry. Several applications throughout the day outperform a single heavy application in the morning.
Keep showers short, between five and ten minutes, and use warm water rather than hot. Hot water strips natural oils from your skin faster, undoing the work your moisturizer is trying to do.
Your Environment Plays a Role
Indoor humidity below 30% directly causes dry skin and dry nasal passages. During winter months, heated indoor air often drops well below that threshold. The recommended range is 30% to 40% humidity. A simple hygrometer (available for a few dollars) can tell you where your home stands, and a humidifier in your bedroom or main living area can keep levels in that range.
Wind and cold air outdoors also accelerate moisture loss. If you’re dealing with dry skin seasonally, increasing your moisturizer’s thickness during colder months, switching from a lotion to a cream or ointment, can compensate for the harsher conditions.
A Simple Routine for Dry Skin
You don’t need a complicated regimen. For most people with dry skin, this covers it:
- Shower or bathe in warm water for no more than ten minutes
- Pat skin damp with a towel rather than rubbing dry
- Apply a ceramide or hyaluronic acid moisturizer to your face while it’s still damp
- Apply a thicker cream or ointment to your body, focusing on legs, arms, and hands
- Reapply to hands after washing and to any dry areas throughout the day
- Use a humidifier if your indoor air falls below 30% humidity
For stubborn rough patches on feet, elbows, or knees, a urea cream in the 10% to 20% range can break down the buildup while also hydrating. Apply it at night and cover with socks or cotton gloves to let it work while you sleep.
