Observe & prepare safely
Keep a short log of where the dermatitis appears, what clears it, how quickly it rebounds, and which topical products, cosmetics, adhesives or occupational exposures contact the skin.

Adult-onset eczema not improving with steroid cream: what may be missing?
When an adult dermatitis pattern keeps returning despite appropriate topical treatment, the next useful step is often to revisit exposure history, treatment response, pathology wording, and whether contact allergy or another inflammatory skin process was actually assessed.
This page is general research orientation. It cannot diagnose you or determine that it is safe to delay medical care.
Initial research compass
Three ways to make the next step more informative.
Audit records & evidence
Retrieve the exact biopsy report and note whether patch testing or additional immunopathology was ever done; list all topical products and their ingredients if available.
Bring a focused question to a clinician
Ask dermatology whether persistent adult-onset dermatitis warrants patch testing, a re-review of pathology, or a different biopsy strategy rather than simply repeating stronger topical therapy.
Important: these are research-orientation ideas, not instructions to self-diagnose, stop prescribed treatment, or perform unsafe home testing. If symptoms may be urgent, seek appropriate in-person care first.
Why a deeper interview can help
A short web page cannot reconstruct a longitudinal medical case.
A full WhatDx case can ask follow-up questions based on your answers, review the records you upload, reconstruct chronology, track treatment response and compare competing explanations across specialties. It then produces a research dossier that you can discuss with a clinician.
The free suitability check is the right next step if you want a case-specific answer about whether that process is likely to add value.

Before you use this guide.
Is this page telling me what condition I have?
No. The same symptom pattern can have many causes, and this page does not have your full history, examination or records. It is intended to organize useful questions, not name a diagnosis.
What if my previous tests were “normal”?
Normal results can be genuinely reassuring, but their meaning depends on what was tested, when it was tested and which question the test can actually answer. A research process can help map that context without assuming that “normal” means “nothing is wrong.”
What does the paid WhatDx session provide?
A detailed adaptive interview, record review, a persistent 90-day case state and an evidence-linked research dossier. It is research support, not prescribing or treatment.
