When should you worry about burning skin if you have contact dermatitis?

Contact dermatitis develops when the skin reacts to an irritant or an allergen. Burning or stinging may accompany redness, dryness, itch, scaling, swelling, or small blisters. Irritant reactions can follow contact with soaps, solvents, cosmetics, or repeated wet work; allergic reactions can follow exposure to a substance the immune system recognises. The rash pattern and exposure history help distinguish it from other causes of burning.

Stop using the suspected product and gently rinse exposed skin with lukewarm water. Pat dry, apply a bland fragrance-free moisturizer, and use a cool damp compress for short periods. Avoid rubbing, heat, fragranced products, and unprescribed steroid creams on the face or skin folds. Keep a list or photograph of products used before the reaction so a clinician can help identify the trigger.

Seek medical advice if burning persists after the suspected exposure ends, covers a large area, repeatedly returns, or comes with extensive blistering, skin peeling, increasing swelling, or open cracks. Arrange prompt care for pus, worsening warmth, spreading redness, fever, or escalating pain. Get emergency help for swelling of the lips or tongue, wheezing, trouble breathing, dizziness, or a rapidly spreading reaction.

Ask whether the pattern fits irritant or allergic contact dermatitis, which ingredients should be avoided, and whether patch testing could help identify an allergen. Ask what treatment is safe for the affected body site and how to respond if burning returns.
