Eczema causes patches of dry, intensely itchy skin that can appear red, rough, or inflamed. The itch is usually the first and most persistent symptom, often starting before any visible rash appears. From there, the condition can look quite different depending on your age, where it shows up on your body, and how long you’ve had it.
The Core Symptoms
Itching is the hallmark of eczema and drives most of the other symptoms. It can range from mild and annoying to so severe it disrupts your sleep. Studies show that sleep disturbances affect 47% to 80% of children with eczema and 33% to 90% of adults. The itch often worsens at night, which compounds the problem.
Beyond the itch, you’ll typically notice some combination of these signs:
- Dry, rough, or scaly skin in the affected areas, sometimes across the entire body
- Red or inflamed patches (on darker skin tones, these may appear brown, purple, or grayish)
- Swelling in actively irritated areas
- Small bumps that may ooze clear fluid when scratched
- Cracked skin, especially in creases or on the hands
Dryness across the skin (not just in flare zones) is one of the most consistent features. In one study of children with eczema, 100% had generalized dry skin. Flares tend to come and go, triggered by things like weather changes, stress, certain fabrics, or allergens. Between flares, the skin may look nearly normal or remain slightly dry and sensitive.
Where Symptoms Show Up by Age
Eczema doesn’t appear in the same places throughout life. In babies, it tends to start on the cheeks, scalp, and outer surfaces of the arms and legs. The diaper area is usually spared because moisture keeps that skin from drying out.
In older children, the pattern shifts to the skin folds: inner elbows, behind the knees, wrists, and ankles. These are the classic “flexural” locations most people associate with eczema. The skin in these creases gets irritated from friction and sweat, making it a prime target for flares.
Adults often break the flexural pattern. Eczema in adults tends to involve the head, neck, and hands more heavily, with fewer flares in the elbow and knee creases. Adults are also more likely to develop coin-shaped (nummular) patches of irritated skin, which can appear on the arms, legs, or torso and look different from the typical eczema rash. Facial redness, particularly around the eyes or on the cheeks, is another common adult feature.
What Chronic Eczema Looks Like
When eczema persists in the same spot for months or years, the skin changes. Repeated scratching and rubbing cause the skin to become thick, rough, and leathery, a process called lichenification. These thickened patches may look darker than the surrounding skin and feel almost rubbery to the touch. They form because constant irritation triggers the skin to build up extra layers as a protective response.
The problem is self-reinforcing. Scratching irritates the nerves in the skin, which triggers more itching, which leads to more scratching. This itch-scratch cycle is one of the hardest parts of eczema to break, and it’s the main driver behind the chronic skin changes that develop over time. Areas prone to lichenification include the back of the neck, ankles, wrists, and inner elbows.
Blisters on Hands and Feet
A specific type of eczema causes tiny, fluid-filled blisters on the fingers, palms, and soles of the feet. These blisters are small, about the size of a pinhead (1 to 2 millimeters wide), and look like small cloudy beads under the skin. They feel firm and deep-seated rather than sitting on the surface.
The blisters are intensely itchy and sometimes painful. They can merge together into larger blisters, and in severe flares they may spread to the backs of the hands and feet. When they eventually dry out, the skin underneath tends to peel and crack. This form of eczema is particularly common in warm weather and can be triggered by sweating, stress, or contact with certain metals like nickel.
Signs of Infection
Broken, cracked eczema skin is vulnerable to bacterial infection, and recognizing the signs early matters. Infected eczema looks different from a regular flare. Watch for increased swelling, warmth, or pain in the affected area. Pus or cloudy fluid oozing from the skin is a strong signal, as is a honey-colored crust that forms when that fluid dries.
Fever alongside a worsening rash is another red flag. Eczema on its own doesn’t cause fevers. If the skin is suddenly more painful than itchy, spreading rapidly, or developing yellow or greenish crusting, that points toward a bacterial infection that needs treatment beyond your usual eczema routine.
Symptoms That Affect Daily Life
The visible rash is only part of living with eczema. The itch can be constant and distracting during the day, making it hard to focus at work or school. At night, it disrupts sleep, and chronic sleep loss compounds into fatigue, irritability, and difficulty concentrating. For children, this can affect behavior and school performance in ways that aren’t immediately connected to a skin condition.
Many people with eczema also notice their skin reacts to things that don’t bother others: rough clothing, fragrances, certain soaps, temperature swings, or even sweating during exercise. This broad skin sensitivity is a core part of the condition, not a separate problem. The skin’s barrier function is compromised in eczema, which means irritants and allergens penetrate more easily, and moisture escapes more quickly. That’s why the dryness and sensitivity extend well beyond the patches where the rash is visible.
