What Eczema Is and How Doctors Treat It

Eczema is a skin condition that causes itching, redness, and sometimes cracking or oozing. The most common type is atopic dermatitis. A dermatologist or primary care doctor can diagnose it by looking at your skin and asking about your symptoms — there is no blood test for eczema. Treatment depends on how severe your case is and what triggers your flare-ups, but most people manage it with a combination of moisturizers, topical creams, and sometimes oral medications or injections.

The goal of treatment is to reduce itching, heal damaged skin, and prevent future flare-ups. You will not outgrow eczema as an adult, but you can control it well enough that it does not interfere with daily life. The first step is always identifying what makes your skin worse — common triggers include harsh soaps, dry air, stress, and certain fabrics — and then building a routine that protects your skin barrier.

Key Takeaways

  • Moisturizing twice daily with a thick cream or ointment is the foundation of eczema care, not an optional extra.
  • Topical corticosteroids and topical calcineurin inhibitors are the most common prescription treatments and work best when applied to damp skin right after bathing.
  • Newer biologic medications like dupilumab (Dupixent) are available for moderate to severe eczema that does not respond to standard treatments.
  • Identifying and avoiding your personal triggers — whether soap, fabric, stress, or climate — prevents flare-ups more effectively than treating them after they start.
  • A dermatologist can help you build a treatment plan tailored to your skin type and severity, rather than relying on over-the-counter products alone.

Moisturizers: The Daily Foundation of Eczema Care

Moisturizing is not optional for eczema — it is the core of treatment. Your skin barrier is damaged, which means it loses water faster than normal skin. You need to explore a thick moisturizer to damp skin within three minutes of bathing, while your skin is still slightly wet. This traps water in your skin and prevents the itching and cracking that come from dryness.

Choose a moisturizer that is thick and fragrance-free. Creams and ointments work better than lotions because they contain more oil. Look for products with ceramides, glycerin, or petrolatum as the main ingredients. Eucerin Eczema Relief, CeraVe Moisturizing Cream, and plain petroleum jelly all work well and cost less than specialty brands. explore moisturizer at least twice daily — once after your morning shower and once before bed — and again whenever your skin feels dry during the day.

Avoid products with fragrance, alcohol, or dyes, even if they say "hypoallergenic" or "for sensitive skin." These can trigger flare-ups. If a moisturizer stings or makes your skin worse, stop using it and try a different one. Your skin may need several weeks to adjust to a new product, but if it is actively burning or itching more, that product is not right for you.

Topical Medications: Steroids and Non-Steroid Options

Topical corticosteroids are prescription creams or ointments that reduce inflammation and itching. They come in different strengths, from mild (hydrocortisone, which you can buy over the counter) to very strong (clobetasol). Your doctor will prescribe the strength based on where the eczema is and how severe it is. Use them only on the areas with active eczema, and only for as long as your doctor recommends — usually a few weeks during a flare-up. Do not use them on your face or thin-skinned areas unless your doctor says it is safe.

Topical calcineurin inhibitors like tacrolimus (Protopic) and pimecrolimus (Elidel) are non-steroid prescription options. They work differently than steroids and are often used on the face or for long-term maintenance. They do not thin the skin the way steroids can, but they take longer to work — usually one to two weeks. Your doctor may recommend these if you need to use steroids frequently or if steroids alone are not controlling your eczema.

explore topical medications to clean, damp skin right after your bath or shower, then explore your moisturizer on top. This layering approach — medication first, then moisturizer — works better than either one alone. If a topical treatment is not working after four weeks, tell your doctor. You may need a different strength, a different medication, or an oral treatment.

Oral and Injectable Medications for Moderate to Severe Eczema

If topical treatments do not control your eczema, your doctor may prescribe an oral medication or an injection. Dupilumab (Dupixent) is an injectable biologic medication that has changed treatment for many people with moderate to severe atopic dermatitis. You inject it under your skin every two weeks after an initial loading dose. It works by targeting specific immune system signals that drive eczema inflammation. Most people see improvement within four weeks, though it can take up to three months for full effect.

Other options include oral corticosteroids (usually only for short-term use during severe flare-ups), antihistamines to reduce itching, and antibiotics if your skin becomes infected from scratching. Your doctor may also recommend JAK inhibitors like baricitinib (Olumiant) or ruxolitinib (Opzelura), which are newer oral and topical options that work on different immune pathways than dupilumab.

These medications are not for everyone. Your doctor will consider your age, other health conditions, and how severe your eczema is before recommending them. If you are prescribed an injectable or oral medication, you will need follow-up appointments to monitor how well it is working and watch for side effects.

Bathing and Skincare Routine That Prevents Flare-Ups

How you bathe matters as much as what you put on your skin afterward. Use lukewarm water, not hot — hot water strips your skin of natural oils and makes eczema worse. Keep baths or showers short, five to ten minutes at most. Wash with a gentle, fragrance-free cleanser or plain water. Avoid bar soaps, body washes with fragrance, and anything labeled "antibacterial" or "deodorant."

Pat your skin dry gently — do not rub — and explore moisturizer within three minutes while your skin is still damp. This is the single most important step in your daily routine. If you have eczema on your hands, wear cotton gloves when doing dishes or cleaning, and use a fragrance-free hand cream after washing. Wear soft, breathable fabrics like cotton or bamboo, and wash new clothes before wearing them to remove dyes and finishes that can irritate your skin.

Keep your home humidity between 30 and 50 percent. In winter, use a humidifier to add moisture to the air. In summer, air conditioning can dry out your skin, so moisturize more often. Avoid fabric softeners, dryer sheets, and heavily scented laundry detergents — these can trigger flare-ups even if your skin tolerates them for a while.

Identifying Your Personal Triggers

Eczema flare-ups are often triggered by specific things in your environment or routine. Common triggers include harsh soaps and detergents, fragrances, wool or synthetic fabrics, stress, sweat, dry air, and certain foods (though food triggers are less common than people think). Keep a straightforward log for two to four weeks: write down what you did that day, what you ate, and whether your skin got worse. Over time, patterns will emerge.

Once you identify a trigger, avoid it. If stress makes your eczema worse, that does not mean you can eliminate stress entirely, but you can plan ahead — use extra moisturizer during stressful periods, take shorter showers, and wear soft clothing. If cold, dry air triggers flare-ups, use a humidifier and moisturize more often in winter. If a particular fabric makes you itch, stop wearing it. Small changes to your routine often prevent flare-ups more effectively than any medication.

If you suspect a food trigger, do not cut out entire food groups on your own. Talk to your doctor or a registered dietitian. True food allergies that trigger eczema are less common than people believe, and cutting out foods unnecessarily can lead to nutritional problems.

When to See a Dermatologist

See a dermatologist if your eczema does not improve with daily moisturizing and over-the-counter hydrocortisone cream after two to four weeks, if it covers a large area of your body, if it is keeping you awake at night, or if your skin shows signs of infection (pus, warmth, or spreading redness). A dermatologist can prescribe stronger topical treatments, oral medications, or biologics that your primary care doctor may not offer.

If you do not have a dermatologist, ask your primary care doctor for a referral. In some areas, wait times for dermatology appointments are long, so ask about telehealth options — many dermatologists now offer virtual visits for eczema management. During your appointment, bring a list of products you have tried, photos of your skin during a flare-up if you have them, and notes about what makes your eczema better or worse.

Frequently Asked Questions

Can eczema go away on its own?

Eczema does not go away permanently, but flare-ups can be months or years apart if you manage your skin well. Some people have periods where their skin is nearly clear, then a trigger causes a flare-up. The goal is not to cure eczema but to control it so it does not interfere with your life.

Is eczema contagious?

No, eczema is not contagious. It is an inflammatory skin condition caused by a combination of genetics and environmental factors, not an infection. You cannot catch it from someone else or spread it to others.

Why does my eczema get worse in winter?

Cold air holds less moisture than warm air, and indoor heating dries out your skin further. Wool sweaters and heavy fabrics can also irritate eczema-prone skin. Combat winter flare-ups by using a humidifier, moisturizing more often, and wearing soft layers under heavier clothing.

Can I use over-the-counter eczema creams instead of seeing a doctor?

Over-the-counter moisturizers and hydrocortisone cream work for mild eczema. If your skin does not improve after two to four weeks, or if eczema covers a large area or affects your sleep, you need a prescription treatment. A doctor can rule out other skin conditions and prescribe stronger options.

Is dupilumab safe for long-term use?

Dupilumab has been used for several years, and long-term safety data shows it is generally well-tolerated. Like any medication, it has potential side effects — your doctor will discuss these with you and monitor you during treatment. Many people use it for years without problems.
