What should you know about nickel allergy what to avoid?

Nickel can be encountered in jewellery, watch backs, belt buckles, buttons, zips, bra fasteners, keys, tools and some device parts. The risk is greater when metal stays against sweaty or rubbed skin. A coating may wear away, so an old barrier is not dependable. Avoidance should be guided by the items that touch your own rash rather than by removing every metal object from daily life.

Choose items labelled nickel-free when available, and use fabric, plastic or another suitable barrier between metal and skin. Keep jewellery and fasteners clean and dry, and remove them during activities that cause sweating or rubbing. Do not scratch an active rash; wash gently and moisturise to support the skin barrier. Record exposures and flare timing so a clinician can decide whether patch testing is useful. A topical corticosteroid may be prescribed for a flare when appropriate.

Seek an appointment when avoidance does not settle the rash, when the trigger is unclear, or when symptoms recur at several body sites. Prompt care is needed for increasing pain, warmth, pus, extensive blistering or fever. Emergency help is appropriate for breathing difficulty or swelling of the face, lips or tongue.

Ask which exposures matter most in your routine, whether a patch test is suitable, how to identify safe replacements, and how long to continue treatment after the skin improves.
