Eczema causes itchy, dry, and inflamed skin that can appear red on lighter skin tones or purple, gray, or dark brown on deeper skin tones. The hallmark symptom is intense itching, sometimes severe enough to disrupt sleep. But eczema looks and feels different depending on your age, where it shows up on your body, and how long you’ve had it.
The Core Symptoms
The most common symptoms of eczema (also called atopic dermatitis) include dry or cracked skin, a visible rash, swelling, and small fluid-filled bumps that may crust over. The rash can range from mildly dry and flaky to raw, weeping patches that ooze clear fluid. On light skin, the affected areas typically look red. On brown or Black skin, the rash often appears as shades of gray, reddish brown, purple, or purplish gray, which can make it harder to recognize and easier to underestimate in severity.
The texture of eczema-affected skin changes too. Early on, it feels rough and scaly. During a flare, the skin may swell, crack, and develop tiny blisters that weep before crusting over. Between flares, the skin often stays noticeably drier than the surrounding areas.
Why the Itch Is So Intense
Itching is the defining feature of eczema, and it’s not ordinary itching. It can be relentless, especially at night, making it difficult to fall or stay asleep. Scratching provides only brief relief because it actually activates more nerve fibers in the skin, making the area itchier. This creates a self-reinforcing loop: the more you scratch, the itchier the skin becomes, and the more damage you do to the skin barrier.
Over time, habitual scratching changes the skin itself. The affected areas become thickened, rough, and leathery, a condition called lichenification. The skin may also develop distinct color changes, appearing darker than your natural tone with sharp borders around the affected patch. These changes can persist even after the itch subsides, sometimes leaving a visible mark or darker area where the rash was.
Where Eczema Shows Up by Age
Eczema doesn’t appear in the same places throughout life. In babies and young children, it tends to show up on the face, cheeks, and outer surfaces of the arms and legs. It’s also more likely to ooze, and children report more severe itching overall compared to adults. The ankles are another common spot in kids that becomes less typical as people age.
In young adults (roughly 18 to 39), eczema shifts toward the creases of the elbows and knees, the wrists, and the neck. This age group is also nearly three times more likely to develop eczema around the eyes compared to children. The patches tend to be drier and less likely to ooze than in childhood.
Older adults (40 and up) experience a different pattern. Eczema is more likely to appear on the elbows, knees, and even the nipples. The skin in affected areas is more prone to lichenification, that thick, leathery texture from chronic irritation. Oozing and severe scratching marks become less common, but the dryness and scaling can be persistent.
Types With Distinct Symptoms
Not all eczema looks the same. The most common form, atopic dermatitis, causes the widespread dry, itchy patches described above. But several other types produce their own recognizable symptoms.
Dyshidrotic eczema targets the hands and feet specifically. It produces tiny, deep-set blisters that look like small cloudy beads, each about the size of a pinhead. These blisters cluster between the fingers, on the palms, and on the soles of the feet. They’re intensely itchy and sometimes painful. As they dry out, the skin peels, cracks, and scales. In severe cases, the blisters merge into larger ones and spread to the backs of the hands or feet.
Nummular eczema creates coin-shaped patches of irritated skin, usually on the arms and legs. These round or oval lesions can be especially itchy and are sometimes mistaken for ringworm. Seborrheic dermatitis, another form, concentrates on oily areas like the scalp, eyebrows, and sides of the nose, producing flaky, yellowish scales.
Signs of Infection
Cracked, broken eczema skin is vulnerable to bacterial and viral infections. Repeated scratching opens the skin barrier, giving bacteria a way in. The signs that eczema has become infected are distinct from a regular flare: the blisters start oozing pus-colored fluid instead of clear fluid, and the dried discharge forms a yellow-to-orange crust on the skin’s surface. The area may also feel warmer than usual, become more swollen, or start to hurt rather than just itch.
Infected eczema needs treatment beyond the usual moisturizing and anti-inflammatory routine. If you notice that yellow crusting, increased pain, or spreading redness, it’s worth getting it evaluated promptly, since untreated skin infections can worsen quickly.
Long-Term Skin Changes
Eczema that persists for months or years leaves its mark on the skin even during calm periods. The most noticeable long-term change is thickening. Skin that has been repeatedly scratched and inflamed develops a rough, almost leathery texture with exaggerated skin lines. This thickened skin can feel stiff and uncomfortable.
Pigment changes are also common, particularly on darker skin tones. Areas that were inflamed may stay darker (hyperpigmentation) or lighter (hypopigmentation) than the surrounding skin for weeks or months after a flare resolves. These color changes aren’t permanent in most cases, but they can take a long time to fade. Keeping flares under control and minimizing scratching are the most effective ways to limit these lasting changes.
