Skin Allergies in Children: How to Recognize, Treat, and Prevent Them

Skin allergies in children are among the most common reasons for pediatric consultations. They can sometimes look alarming and worrying for parents, but most are mild and can be well controlled with appropriate care. Learning how to recognize them is the first step.

The Most Common Skin Allergies in Children

1. Atopic Dermatitis (Eczema)

Atopic dermatitis is one of the most common inflammatory skin conditions in children, affecting around 15–20% of children in industrialized countries. It often begins before the age of 5 and may persist into adolescence.

Symptoms:

• Red, dry, scaly patches
• Intense itching, often worse at night
• Location varies with age: cheeks and forehead in infants, elbow and knee folds in older children
• Generally dry and sensitive skin between flare-ups
• Symptoms that come and go in flares and periods of remission

Common triggers:

• Harsh soaps and detergents
• Synthetic fabrics or wool
• Excessive sweating
• Stress and viral infections
• Certain foods, such as eggs, milk, and peanuts, especially in infants

2. Hives (Urticaria)

Hives appear as raised, red, and very itchy patches that usually come and go within 24 hours. They can be acute, lasting less than 6 weeks, or chronic.

• Allergic causes: foods such as strawberries, shellfish, peanuts, and eggs; medications; insect bites
• Non-allergic causes: viral infections, which are very common in children, as well as cold, heat, or pressure
• Angioedema: deeper swelling of the lips, tongue, or eyelids — an emergency if it affects breathing

3. Contact Dermatitis

Contact dermatitis is a localized reaction caused by direct contact with an allergen or irritant.

Common triggers include:

• Costume jewelry containing nickel
• Cosmetics, shampoos, and perfumes
• Latex, such as gloves and balloons
• Plants such as nettles, poison ivy, or poison sumac
• Textile dyes

4. Allergic Reactions to Insect Bites and Stings

Most reactions to insect bites and stings are local and mild. However, in children with severe allergies, a bee, wasp, or hornet sting can trigger anaphylaxis — a life-threatening emergency requiring immediate administration of adrenaline (epinephrine).

When Should You Seek Emergency Care?

Certain symptoms require immediate medical attention:

• Difficulty swallowing or breathing after an insect sting or eating a food
• Rapid swelling of the face, tongue, or neck
• Loss of consciousness or sudden paleness
• Widespread hives accompanied by fever and a significant deterioration in the child's general condition

Treatments for Skin Allergies in Children

Treatment depends on the type of skin allergy, its severity, and the child's age.

Eczema

• Daily emollients: the foundation of treatment, helping restore the skin barrier
• Topical corticosteroids: for flare-ups, used for a short period and adapted to the affected area
• Calcineurin inhibitors (tacrolimus): an alternative to topical steroids for sensitive areas
• Antihistamines: may sometimes be used to help manage itching
• Dupilumab: a biologic treatment that may be prescribed for certain severe forms of eczema in eligible children

Hives

• H1 antihistamines: a mainstay of treatment for urticaria
• Oral corticosteroids: sometimes used for short courses in severe cases
• Epinephrine auto-injector: for children at risk of anaphylaxis

Contact Dermatitis

• Avoiding the allergen: the priority measure
• Topical corticosteroids: to relieve acute inflammation when prescribed
• Allergy assessment with patch testing: to identify the specific allergen responsible
