Decode the confusing parts — side by side.
Allergy vs. sensitivity vs. intolerance
Allergy
An immune-system response that can be immediate and, in some cases, serious. Worth professional testing and a clear action plan.
Sensitivity
A non-allergic reaction — think headaches or skin irritation from fragrance — that\u2019s real but works differently from an allergy.
Intolerance
Usually digestive and dose-related. Often about how much, not whether — and different again from the two above.
Fragrance-free vs. unscented
Fragrance-free
Generally means no fragrance ingredients were added. Usually the safer starting point if scent is your trigger.
Unscented
Often means a masking scent was added to cover other smells — so it can still contain fragrance chemicals.
How to read a product label in under a minute
- Scan for “fragrance” or “parfum” first
- Check for your known triggers near the top of the list
- Treat “unscented” as “verify,” not “safe”
- When unsure, patch test before full use
Terms you\u2019ll see a lot, in everyday words
Hypoallergenic
A marketing term, not a guarantee — it suggests fewer common allergens but isn\u2019t strictly regulated.
Polysensitization
Reacting to more than one substance. Common, manageable, and easier with organized notes.
Contact dermatitis
Skin irritation or inflammation from something it touched — a frequent culprit behind mystery rashes.
Patch testing
Applying a small amount to a small area first, to check for a reaction before full use.
Fragrance / parfum
An umbrella label that can hide many individual scent chemicals under one word.
Sensitive skin
Skin that reacts more readily to products or environment — a description, not a diagnosis.
Questions we hear all the time
It suggests a product is formulated to cause fewer allergic reactions, but the term isn\u2019t strictly regulated — so treat it as a helpful hint, not a guarantee.
Not always. “Unscented” can include a masking fragrance. If scent is your trigger, “fragrance-free” is usually the safer starting point.
Stop using it, note the product and ingredients, and consider a patch test before trying anything new. If it\u2019s severe or persistent, see a clinician.
Look for “fragrance-free” (not just “free & clear” marketing) and fewer additives. We focus on how to evaluate options rather than pushing a single brand.
