How is contact dermatitis treated?

Treatment depends on whether the reaction followed an irritant, such as a harsh cleanser, or an allergy to a product or material. Removing the suspected trigger gives the skin a chance to settle. A clinician may recommend a topical corticosteroid for inflamed areas; the strength and application plan depend on the body site and the severity of the rash. Moisturiser helps reduce dryness and cracking, while cool compresses can ease heat and itching.

Stop using newly introduced cosmetics, detergents, adhesives, or skincare products until the cause is clearer. Rinse exposed skin gently, avoid scrubbing, and choose fragrance-free moisturiser. Wear protective gloves for wet work, with a soft layer underneath if gloves themselves irritate you. Do not restart a suspected product simply to test it when the reaction was strong; a clinician can help identify safer alternatives.

Arrange medical advice if the rash is spreading, blistering, painful, recurrent, or not settling after the suspected trigger is removed. Seek urgent help for swelling of the lips, tongue, or face, trouble breathing, widespread blistering, or skin that is rapidly peeling. A clinician can also assess infection when there is increasing warmth, pus, or fever.

Ask which ingredient or exposure is most suspicious, how long to use the prescribed cream, and which moisturiser is suitable for the affected site. Ask whether patch testing could help when the rash keeps returning.
