What is used for severe denudation in cases of diaper dermatitis?

Hydrocortisone
Carboxymethylcellulose/petrolatum/zinc oxide
Antibiotic ointment
Barrier cream only

The correct answer is: Carboxymethylcellulose/petrolatum/zinc oxide

In cases of severe denudation associated with diaper dermatitis, the use of a combination formulation such as carboxymethylcellulose, petrolatum, and zinc oxide is particularly effective. This formulation serves multiple purposes: - **Carboxymethylcellulose** acts as a protective barrier, helping to create a moist environment that facilitates healing while preventing irritation from moisture and fecal matter. - **Petrolatum** is an occlusive agent that helps to seal in moisture and provides a barrier against irritants, further protecting the skin from external factors that can exacerbate the condition. - **Zinc oxide** is well known for its skin-protective properties, as it not only acts as a barrier but also has anti-inflammatory effects, helping to soothe the irritated skin. The combination of these ingredients provides a robust approach to treating severe cases of diaper dermatitis by promoting healing and protecting the skin from ongoing irritation.
