This comprehensive guide will explore the ins and outs of diaper rash, also known as diaper dermatitis. We’ll dive into what causes this condition, how to spot its signs, and the most effective ways to treat it. Additionally, we’ll share practical tips for prevention and care, helping parents and caregivers manage and reduce the occurrence of diaper rash in their children.
What is Diaper Rash?
Diaper rash, also known as diaper dermatitis, is an inflammatory reaction of the skin in the perineal and perianal areas (diaper area). It is the most common skin disorder seen in young infants, affecting about 50% of babies and accounting for approximately 25% of visits to primary care physicians related to dermatologic complaints in the first year of life.
Diaper rash can range from mild to severe and may present with various symptoms such as redness, swelling, and discomfort in the diaper area. The condition results from a combination of factors, including increased moisture, prolonged contact with urine or feces, and other irritants like detergents.
Types of Diaper Rash
There are several types of diaper rash, each with its own characteristics and causes:
- Irritant contact dermatitis: The most common type, caused by irritation from urine, feces, diapers, or skin care products. It appears as pink or red patches on the skin.
- Candida diaper rash: Caused by an overgrowth of the fungus Candida albicans, presenting with erythema, scaly plaques, and satellite pustules or papules.
- Bacterial diaper rash: Caused by bacterial infections, such as Staphylococcus aureus or Streptococcus pyogenes, ranging from small papules and pustules to large, fragile blisters or fiery-red erythema.
- Allergic contact dermatitis: A reaction to fragrances or preservatives in diapers, wipes, or creams, involving any part of the skin where the product was applied.

Common Causes
The primary cause of diaper rash is the increased moisture that results from wearing diapers, leading to increased friction and maceration. This makes the skin more susceptible to damage and penetration by skin microorganisms and other irritants. Changes in skin pH also play a role, as an increase in pH around the diaper area from the breakdown of urinary urea can increase fecal enzyme activity, further damaging the skin.
Risk Factors
Several factors can increase the risk of developing diaper rash:
- Age: Newborns and infants are at an increased risk due to skin immaturity.
- Diet: Changes in diet as the infant grows are related to changes in intestinal microbiota and stool pH. Breastfeeding has been proven to be a protective factor.
- Frequency of diaper changes: Prolonged contact with irritants such as urine and feces increases the risk of skin inflammation.
Understanding the types, causes, and risk factors associated with diaper rash is essential for parents and caregivers to effectively prevent, identify, and manage this common condition in infants.
Symptoms and Diagnosis
Diaper rash can range from mild to severe and may present with various symptoms such as redness, swelling, and discomfort in the diaper area. The condition results from a combination of factors, including increased moisture, prolonged contact with urine or feces, and other irritants like detergents.
The presentation may begin with a history of increased frequency of stools or changes in its appearance (loose), followed by the development of erythema around the diaper area about two days after. Physicians must elicit from parents hygiene practices, frequency of diaper changes, type of diapers used, and use of any substance that may be worsening the irritation.
Physical Signs
Clinical presentation can be variable. Skin findings include erythema, papules, scaling, and erosions that can be present around the thighs, scrotum, suprapubic area, and buttocks. It usually spares skin creases.
Candida dermatitis presents with erythema and scaly plaques, accompanied by edema. The most characteristic feature is the presence of satellite pustules or papules. Candidal dermatitis can be present in the skin folds. In severe cases, erosions and ulceration can occur.
Clinical manifestation of Staphylococcus aureus infection can range from small papules and pustules to large, fragile blisters of bullous impetigo. Streptococcus pyogenes presents with fiery-red erythema and maceration that involves the skin folds.

When to See a Doctor
Many parents are hesitant to call their pediatrician for “just a diaper rash”. However, there are 5 signs indicating when you should call your child’s doctor:
- If your child has open sores, raised red bumps, or blisters in the diaper area.
- If the skin is oozing or bleeding.
- If the rash spreads beyond the diaper area to the arms or face.
- If your baby develops a fever, which can indicate an infection.
- If the rash does not start to improve in two to three days, but rather seems to be worsening.
Differential Diagnosis
The differential diagnosis of diaper dermatitis includes any skin condition that can present around the diaper area.
- Seborrheic dermatitis usually presents in the first month of life. Characterized by skin erythema and scaling, that begins in the scalp and distributes to the face. It has the potential to spread to the diaper area, making babies more susceptible to the development of irritant diaper dermatitis.
- Atopic dermatitis usually presents between 3 and 12 months of age. The presentation includes extreme pruritus with dryness and erythema. Lesions typically involve skin flexures. The diaper area is generally spared.
- Allergic contact dermatitis, secondary to reactions to fragrances or preservatives. It usually occurs after the introduction of a new skin product, and it involves any part of the skin where the product was applied.
Other differential diagnoses that need to be taken into consideration include tinea cruris, scabies, acrodermatitis enteropathica, biotin deficiency, Langerhans cell histiocytosis (Letterer-Siwe disease), congenital syphilis, Kawasaki disease, and HIV infection.
Diaper dermatitis is a clinical diagnosis based on history and physical examination findings. Overall, there is no need to perform any laboratory testing. However, when considering infection by Candida albicans, confirmation of the diagnosis by examination with KOH can be useful, although not necessary. If there is suspicion of bacterial infection, Gram staining can be performed.
Treatment Options
Treating diaper rash involves a combination of home remedies, over-the-counter treatments, and prescription medications, depending on the severity of the condition.
Home Remedies
Keeping the diaper area clean and dry is crucial for treating and preventing diaper rash. Change dirty diapers as soon as possible, and use water and a soft washcloth or alcohol-free, fragrance-free baby wipes to gently clean the area. Allow the skin to air dry before putting on a new diaper. Some parents claim that applying breast milk to the affected area can help soothe and heal the rash due to its antibacterial properties. However, studies suggest that using a barrier cream is more effective than breast milk, especially for moderate to severe cases.
Over-the-Counter Treatments
Over-the-counter (OTC) creams are effective for treating mild to moderate diaper rash. These creams act as a barrier between the baby’s skin and moisture from urine, stool, or sweat. Healthcare providers often recommend using OTC creams containing zinc oxide, such as Desitin, Triple Paste, and Balmex. When changing the diaper, apply a thick layer of cream to cover the rash completely. Petroleum jelly (Vaseline) is another OTC option that can block moisture from the child’s skin. Some studies suggest that massaging sunflower oil or coconut oil into the diaper rash may provide a barrier, similar to barrier creams. However, more research is needed to confirm their effectiveness.
Prescription Medications
If the diaper rash is severe or caused by a bacterial or yeast infection, a healthcare provider may prescribe medicated creams or ointments. Clotrimazole are commonly used for treating diaper rashes caused by yeast, while mupirocin and bacitracin are prescribed for bacterial skin infections in the diaper area. It is essential to follow the healthcare provider’s instructions when using prescription medications and to complete the full course of treatment, even if the rash appears to be improving.
When treating diaper rash, it is important to avoid using products that contain fragrances, dyes, or irritants, as these can worsen the condition. Do not use powders, such as baby powder, cornstarch, or baking soda, as they can be dangerous if inhaled by the baby. If the rash does not improve within a few days or is accompanied by open sores, fever, or other symptoms, contact a healthcare provider for further evaluation and treatment.
Prevention and Care
Preventing diaper rash involves following best practices for diaper changing, choosing the right products, and considering dietary factors that may impact your baby’s skin health.
Frequent diaper changes are crucial to minimize contact with irritants like urine and stool. Change diapers as soon as they become soiled, and allow the skin to air dry before applying a new diaper. Use fragrance-free, alcohol-free wipes or a soft washcloth with water to gently clean the diaper area.
When selecting diapers and skincare products, opt for those that are free of harsh chemicals, fragrances, and dyes. Disposable diapers with a superabsorbent core can help keep moisture away from the skin. Apply a thick layer of barrier cream containing zinc oxide or petrolatum at each diaper change to protect the skin from irritants.

Your baby’s diet can also play a role in preventing diaper rash. Breastfed infants tend to have a lower incidence of diaper rash compared to formula-fed babies. If your baby is eating solid foods, be mindful of acidic foods like citrus fruits and tomatoes, which can contribute to diaper rash. Starchy foods like rice, potatoes, and bread can help bulk up stools and reduce irritation.
By implementing these preventive measures and addressing any signs of diaper rash promptly, you can help keep your baby’s delicate skin healthy and comfortable.
