A very common form of skin irritation in infants and young children who are still in diapers. Red patches, sometimes oozing, covering the buttocks, skin folds, thighs, and genital area. The skin is shiny, sensitive, and sometimes painful to the touch; the baby appears uncomfortable during diaper changes. Most babies experience at least one episode before age 2. It is generally a mild condition that resolves with appropriate care. Early treatment limits discomfort and prevents progression to a potential secondary infection.

A combination of irritants concentrated in the moist, enclosed environment of the diaper: prolonged contact with urine and stool (digestive enzymes, ammonia, bile salts), excessive moisture that promotes maceration, repeated rubbing from the diaper and clothing, friction during diaper changes that are too vigorous, unsuitable products (alcohol-based wipes, perfumes, harsh soaps), diarrhea (gastroenteritis, teething, antibiotics—more acidic stools), introduction of solid foods (changes in bowel movements and acidity), secondary infection with Candida albicans (yeast infection) or bacterial infection on compromised skin, rare allergic reaction to a component of the diaper or a product used. These factors often occur together.

How can you prevent it on a daily basis?

Simple but consistent steps. Frequent diaper changes: every 2–3 hours on average, immediately after each bowel movement. Gently clean with lukewarm water using a cotton pad, or with an oil-and-calcium-based liniment, without rubbing. Gently pat dry, paying special attention to the skin folds. Allow the area to air dry before putting on a clean diaper, whenever possible. Use a diaper that fits well but isn’t too tight, and is the correct size. Apply a zinc oxide barrier cream as needed in cases of diarrhea or teething. Use products suitable for delicate skin (free of fragrance, alcohol, dyes, and harsh preservatives). Wash hands thoroughly after every diaper change. Traditional oil-and-lime liniment (olive oil + lime water) is a popular choice.

Q: What products should be used to treat it?

Apply a thick layer of zinc oxide cream at every diaper change (provides a barrier, drying effect, and mild antiseptic action). Water-based pastes containing zinc and talc (cold cream) for severe irritation. Gentle plant-based oils (sweet almond, calendula) applied sparingly to clean, dry skin. Thermal water sprays (Avène, La Roche-Posay, Uriage) for occasional soothing. Oil-and-lime liniment for daily cleansing. Specific soothing baby creams containing panthenol, allantoin, or Cica. Avoid: talcum powder (respiratory risk), routine antiseptics, dyes such as eosin without medical advice, self-prescribed topical corticosteroids, concentrated essential oils for infants, fragrances, and alcohol.

Q: Which diapers and wipes should you choose?

Disposable diapers: Choose ultra-absorbent models that are fragrance-free, contain no added lotions, and are the right size. Cloth diapers: Well-tolerated, provided they are changed very frequently, washed at 60°C with a mild, fragrance-free detergent, rinsed thoroughly, and completely dry before reuse. Diapers made from natural or eco-friendly materials (cotton, certified cellulose, phthalate-free, fragrance-free, chlorine-free) are sometimes better tolerated by sensitive skin. Choose wipes that are alcohol-free, fragrance-free, and free of harsh preservatives (MIT, parabens). Cotton + water or liniment: the gentlest option, preferred in cases of established diaper rash or very sensitive skin. Test only one new product at a time.

Q: When should you see a doctor?

Most diaper rashes improve within 2–4 days with proper care. Situations warranting a pediatrician’s consultation: no improvement after 3–5 days of proper care, rapid worsening despite treatment, very extensive, deep, or weeping lesions; open sores; honey-colored crusts; blisters or pustules (secondary infection); spread beyond the diaper area; satellite lesions at the periphery (possible Candida infection); feverish baby (temperature above 38 °C), markedly irritable or uncomfortable, history of eczema or chronic skin condition, diagnostic uncertainty. A pediatrician may prescribe an antifungal cream (for a fungal infection), a topical antibiotic (for a secondary infection), or a mild-strength topical corticosteroid for a very short course of treatment. Self-medication should be avoided.

What is diaper rash?

Diaper rash, or diaper dermatitis, is a very common skin irritation in infants and young children who still wear diapers. It appears as red patches—sometimes oozing—that cover the buttocks, skin folds, thighs, and genital area. The skin may become shiny, sensitive, and sometimes painful to the touch, and may visibly cause discomfort for the baby during diaper changes.

Although most babies experience at least one episode of diaper rash before the age of 2, this condition is generally mild and resolves with proper care. Early treatment limits discomfort and prevents the condition from progressing to a secondary infection. Additional resources are available for infants and babies in general.

What are the causes?

Diaper rash results from a combination of irritating factors concentrated in the moist, enclosed environment of the diaper:

Prolonged contact with urine and stool: digestive enzymes, ammonia, and bile salts that irritate an infant’s delicate skin
Excessive moisture, which contributes to skin maceration
Repeatedrubbing from the diaper and clothing
Friction caused by changing the diaper too vigorously
Inappropriate products: alcohol-based wipes, perfumes, harsh soaps
Diarrhea (gastroenteritis, teething, antibiotics): more acidic, more frequent stools
Introduction of solid foods, leading to changes in bowel movements and stool acidity
Secondary infection with Candida albicans (yeast infection) or bacteria on compromised skin
Rareallergic reaction to a component of the diaper or a product used

Several combined factors often explain the onset: waiting too long to change a diaper after a bowel movement, using scented wipes, and a period of introducing solid foods or teething can trigger an episode. Specific resources are available regarding the introduction of solid foods in general.

How can it be prevented on a daily basis?

Prevention relies on simple but consistent steps:

Frequent diaper changes: every 2 to 3 hours on average, immediately after each bowel movement
Gently clean with lukewarm water using a cotton pad, or with an oil-and-calcium-based liniment, without rubbing
Careful drying by patting, especially in the skin folds
Air-drying before putting on a fresh diaper, whenever possible
A diaper that fits well but isn’t too tight, in the right size (look out for pressure marks)
Applya zinc oxide-basedbarrier cream as needed in case of diarrhea or teething
Products suitable for delicate skin: fragrance-free, alcohol-free, dye-free, and free of harsh preservatives
Alwayswash your hands before and after a diaper change

Oleo-calcareouslin iment—a mixture of olive oil and lime water—remains a popular classic for gentle cleansing while leaving a protective film. Specific resources are available for diaper changes and baby care in general.

What products should be used to treat it?

Treating established diaper rash involves a combination of gentle cleansing and the application of barrier care products:

Zinc oxide creams applied in a thick layer at every diaper change: barrier effect, drying, and mildly antiseptic
Water-based pastes containing zinc and talc (cold cream) for severe irritation
Mild vegetable oils: sweet almond, calendula, applied lightly to clean, dry skin
Thermal water sprays (Avène, La Roche-Posay, Uriage) to provide occasional soothing relief
Oleo-calcareous liniment for daily cleansing
Specializedsoothing babycreams containing panthenol, allantoin, or centella asiatica

Forzinc oxide, calendula, andsweet almond in general, specific resources are available. Avoid: talcum powder (respiratory risk, inhalation), routine antiseptics, dyes such as eosin without a doctor’s advice, self-medication with topical corticosteroids, concentrated essential oils for infants, fragrances, and alcohols. Specific resources are available forbaby skin irritation andsoothing products in general.

Which diapers and wipes should you choose?

The choice of diapers directly influences the occurrence of diaper rash:

Disposable diapers: Choose ultra-absorbent, fragrance-free models without added lotions, in the correct size
Cloth diapers: Well-tolerated provided they are changed very frequently, washed at 60°C with a mild, fragrance-free detergent, thoroughly rinsed, and completely dry before reuse
Diapers made from natural or eco-friendlymaterials (cotton, certified cellulose, phthalate-free, fragrance-free, chlorine-free) are sometimes better tolerated by sensitive skin
Wipes: Choose alcohol-free, fragrance-free, and free of harsh preservatives (MIT, parabens)
Cotton + water or liniment: the gentlest alternative, preferred in cases of established diaper rash or very sensitive skin

For wipes, biodegradable wipes, and organic cotton in general, specific resources are available. Testing only one new product at a time helps identify potential intolerances.

When should you see a doctor?

Most diaper rashes improve within 2 to 4 days with proper care. However, there are several situations that warrant a pediatric consultation:

No improvement after 3 to 5 days of proper care
Rapid worsening despite treatment
Extensive, deep, or weeping lesions
Open sores, honey-colored crusts, blisters, or pustules (suspected secondary infection)
Spread beyond the diaper area
Satellite lesions at the periphery suggestive of a Candida infection
Baby with a fever (temperature above 38 °C), is irritable, or appears markedly uncomfortable
History of eczema or chronic skin condition
Diagnostic uncertainty with atopic dermatitis, psoriasis, or another skin condition

Depending on the diagnosis, the pediatrician may prescribe an antifungal cream (in case of a fungal infection), a topical antibiotic (in case of a bacterial superinfection), or a low-potency topical corticosteroid for a very short course of treatment.Self-medication with corticosteroids or antifungals without medical advice is contraindicated in infants. Foreczema in general, specific resources are available.

What role does diet play?

Diet can influence the onset of rashes, particularly during transitional periods:

Introduction of solid foods: changes in bowel movements and stool acidity can temporarily compromise the skin’s barrier
Acidic foods (tomatoes, citrus fruits, berries) or very spicy foods—passed through breast milk in breastfed infants, or consumed directly by children who have started solid foods
Antibiotics in children or breastfeeding mothers: imbalance in gut flora, possible diarrhea, creating conditions conducive to skin fungal infections
Diarrhea of any cause (gastroenteritis, food intolerance, teething): more frequent, more acidic, and more irritating stools
Food allergies or intolerances are rare but possible: monitor for a potential link to the introduction of a new food

Identifying the trigger allows for temporary adjustments to care and enhanced barrier protection. During an acute episode, changing diapers more frequently, allowing ample time for the skin to air out, and generously applying zinc oxide cream are the most effective measures. Your pharmacist remains a valuable resource to support this daily care, in addition to regular pediatric follow-up.
