Did you know 'unscented' can still contain fragrance?
'Unscented' and 'fragrance-free' are not the same thing. One can still hide a masking fragrance. The plain-English difference, and which claim to trust for sensitive skin.
The fact, stated plainly
“Unscented” and “fragrance-free” sound like the same thing, but they are not. Fragrance-free means no fragrance has been added. Unscented usually means the product has no noticeable smell, which can be achieved by adding a masking fragrance to cover the natural odour of the base ingredients. So an “unscented” product can still contain fragrance, the very thing a sensitive person may be trying to avoid.
Why “unscented” can still contain fragrance
Some raw ingredients have a smell of their own, and it is not always pleasant. To make a product seem scent-free, a manufacturer can add a small amount of masking fragrance that neutralises that base odour. The result smells of nothing in particular, so it earns the word “unscented”, yet a fragrance is genuinely present in the formula. For someone whose skin reacts to fragrance, that hidden masking fragrance can be enough to cause a flare, even though the product does not smell of anything.
“Fragrance-free”, by contrast, is meant to signal that no fragrance, scented or masking, has been added at all. It is worth knowing that neither term is tightly regulated, so both are used fairly loosely. That is exactly why the ingredient list matters more than the word on the front.
Why it matters
Fragrance is the single most common cause of cosmetic contact allergy, so this wording difference has real consequences. Reaching for “unscented” thinking it is the safe option can mean you are still applying masking fragrance to reactive skin, and then being baffled when it flares. It is one of the most common label mix-ups there is, and an easy one to fix once you know the difference.
Who this affects most
This matters most for people with sensitive, fragrance-reactive or eczema-prone skin, who are the ones most likely to be choosing “gentle-looking” products in the first place. Parents choosing washes and creams for a child with eczema are a common example, since fragrance-free is generally preferred for eczema-prone skin, and reaching for “unscented” instead can quietly undermine that.
How to read the label
Do not rely on the headline word. Turn the pack over and check the ingredients:
- Favour products labelled “fragrance-free”, but still confirm on the list.
- Look for “parfum”, “fragrance” or “aroma”, any of which means fragrance is present.
- Scan the end of the list for named allergens such as limonene, linalool, citronellol and geraniol, which signal a fragrant product even if the front says otherwise.
If a product only says “unscented”, treat that as a prompt to read the ingredients before trusting it.
What to do
For sensitive or eczema-prone skin, choose “fragrance-free” and verify it on the ingredients. This is the same reason dermatologists prefer fragrance-free for eczema. Build a short habit of checking the tail of the ingredient list for fragrance terms, and if you are unsure, patch test a new product on the inner forearm for a few days before using it more widely.

When to see a professional
A pharmacist can point you towards genuinely fragrance-free basics if you are not sure where to start. See a GP if fragrance reactions are frequent, persistent or spreading, or if you cannot identify what is causing them. A GP can refer you to a dermatologist for patch testing, which pinpoints exactly which fragrance chemicals you react to, so you can avoid your specific triggers rather than guessing from front-of-pack claims.

Check it against your own list
A free tool like Skincarisma or INCIDecoder explains a product’s ingredients, but not whether it contains your triggers. A personal-list app like ClearaScan lets you save fragrance and your other triggers once and scan any product, cosmetic, food or medication, against your ingredient guard list, flagging only yours, so “unscented” claims cannot catch you out. It also keeps a Reaction Journal, a shared Care Circle, and a Trusted Products list, and it is currently in early access.

Common questions
What is the difference between unscented and fragrance-free?
Fragrance-free means no fragrance has been added. Unscented usually means the product has no noticeable smell, which can be achieved by adding a masking fragrance to cover the natural odour of the base ingredients. So an unscented product can still contain fragrance.
Why would a product add fragrance to smell of nothing?
Some raw ingredients have their own odour. A masking fragrance is added to neutralise that smell so the product seems scent-free, even though a fragrance is present. For a fragrance-sensitive person, that hidden fragrance can still cause a reaction.
Which claim should I trust for sensitive skin?
Fragrance-free is generally the more reliable claim, but confirm it on the ingredient list. Look out for parfum, fragrance, aroma, or named allergens such as limonene and linalool, any of which means fragrance is present.
Are these terms legally defined?
The terms are marketing descriptions rather than tightly regulated definitions, so they can be used loosely. That is exactly why the ingredient list matters more than the wording on the front of the pack.
When should I get advice about fragrance reactions?
See a pharmacist for fragrance-free recommendations, and a GP if reactions are frequent or persistent. A GP can refer you to a dermatologist for patch testing, which pinpoints which fragrance chemicals you react to.
