Understanding Eczema: Types, Causes, Symptoms, and Treatment Options
Eczema, also known as dermatitis, is a common skin condition affecting its outermost layer, the epidermis. The skin comprises three layers: epidermis, dermis, and subcutaneous tissue. Eczema is marked by inflammation, dryness, and persistent itching, leading to patches of rough, red, or blistered skin. It can affect individuals of all ages, from infants to adults, and may persist or recur over time. Eczema often results in skin that is easily irritated, prone to infections, and lacking protective barrier function.
- Family history of allergies or asthma increases the risk. Skin barrier defects can lead to dryness and infections.
- Though the precise cause is unknown, an overactive immune response to allergens and irritants is suspected.
- Triggers include stress, harsh skincare products, extreme temperatures, and rough textiles.
- In infants, symptoms include dry, itchy patches, often on the scalp and cheeks, with possible oozing or crusting. Persistent scratching can cause infections and inflammation.
- In adults, eczema may appear as rashes in the elbows, knees, neck, or other areas, leading to thickened, scaly skin and chronic itchiness. Common locations include wrists, hands, legs, and around the eyes.
- Overall, affected skin appears dry, flaky, red, or darker, with pigmentation changes over time.
- There is no cure; treatment focuses on managing symptoms and preventing flare-ups.
- Home care involves wearing soft fabrics, using gentle moisturizers, avoiding harsh soaps, taking lukewarm baths, and keeping nails trimmed to reduce scratching.
- Medications include topical steroids, calcineurin inhibitors, and oral medications to control inflammation and itchiness.
- Phototherapy, involving controlled UV exposure, may be recommended for moderate cases.
