Insights
Severe allergic reactions to benzoyl peroxide, a common ingredient, can occur. This case highlights a child’s severe allergic contact dermatitis to benzoyl peroxide, requiring hospitalization.
Area of Science:
- Dermatology
- Allergology
- Pediatric Medicine
Background:
- Benzoyl peroxide is a common ingredient in acne treatments.
- Allergic contact dermatitis (ACD) to benzoyl peroxide affects up to 6.5% of exposed individuals.
- Irritant contact dermatitis is more common than ACD and can be distinguished by clinical presentation and patient history.
Abstract:
Allergic contact dermatitis to benzoyl peroxide can occur in up to 6.5% of those with a history of exposure to this potential allergen. Conversely, irritant contact dermatitis is very common with benzoyl peroxide and can be differentiated from allergic contact dermatitis based on the patient's history and clinical signs and symptoms. We present a case of a paediatric patient with patch test-confirmed severe allergic contact dermatitis to benzoyl peroxide requiring hospitalisation and systemic treatment.
