Did You Know Dermatologists Pick 'Fragrance-Free' Over 'Unscented' for Eczema?
It is a small wording difference with a real impact for sensitive and children's skin. Why dermatologists are specific about 'fragrance-free', what 'unscented' can still hide, and how to check a label lives up to it.
The fact, stated plainly
When dermatologists advise on eczema and sensitive skin, they tend to say “fragrance-free”, not “unscented”, and the distinction is deliberate. Fragrance-free means no fragrance has been added. Unscented often means the product has no obvious smell, but it may still contain masking fragrance added to cover the base ingredients’ odour, fragrance that can still flare reactive skin.
Why the wording matters
The two terms are not regulated to mean the same thing, and that is the crux. “Unscented” describes the end result you notice, no detectable smell, and manufacturers can achieve that by adding a small amount of fragrance to neutralise the raw, sometimes greasy or chemical, smell of the base. So an unscented product can, paradoxically, contain fragrance. “Fragrance-free” is a claim about ingredients rather than smell, and it is the wording that maps to what eczema-prone skin actually needs: nothing fragranced going on at all. Because neither phrase is tightly policed, the ingredients list is what settles it, and that is where a careful shopper wins back the control the front of the pack does not give them.
Why fragrance is the problem for eczema
Fragrance is the single most common cause of cosmetic contact allergy, and a frequent eczema irritant, so for eczema-prone and children’s skin, removing it is one of the highest-value steps. Eczema skin has a weakened barrier, which lets more of any irritant or allergen through, so it reacts to fragrance more readily than robust skin does. Choosing “unscented” by mistake can mean you are still applying the very thing you were trying to avoid, which is exactly how a switch that should help ends up making no difference.
Who it affects most
Anyone with eczema, atopic or contact dermatitis, or a known fragrance allergy, and parents choosing products for babies and children, whose skin is thinner and more permeable. People who have reacted to scented products before are the most likely to benefit from being strict about the wording.
How to check a label lives up to it
- Look for “fragrance-free” on the front, then confirm it on the ingredients.
- There should be no parfum, fragrance or aroma anywhere in the list.
- Check the end of the list for named fragrance allergens such as limonene, linalool, citronellol, geraniol or eugenol. UK and EU rules require these to be named individually, so they are a useful tell.
- Remember essential oils count as fragrance. A product scented “naturally” is still scented.
If any of those appear, it is not truly fragrance-free, whatever the front of the pack says. Our how to switch to fragrance-free guide walks through building a routine around it.
What to do about it
Choose fragrance-free versions of the products that stay on the skin longest, moisturisers, cleansers, sunscreens and anything for the face, first, since those give the biggest return. Introduce one new product at a time and patch test it on a small area for a few days before using it more widely, so if something does flare, you know which product caused it.
When to see a professional
See your GP or a pharmacist if eczema is widespread, weeping, infected, or not settling with fragrance-free basics and an emollient. Ask about a dermatology referral and patch testing if flares continue despite avoiding fragrance, as another contact allergen may be involved. A pharmacist can also help you choose suitable fragrance-free emollients from the range available.
Check it against your own list
A free tool like Skincarisma or INCIDecoder lets you check 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. It also keeps a Reaction Journal, a shared Care Circle so family or carers can scan for you, and a Trusted Products list, and it is currently in early access.

Common questions
What is the difference between fragrance-free and unscented?
Fragrance-free means no fragrance has been added. Unscented usually means the product has no obvious smell, but it may contain a masking fragrance added to cover the smell of the base ingredients. That masking fragrance can still flare reactive skin.
Why do dermatologists prefer fragrance-free for eczema?
Fragrance is the single most common cause of cosmetic contact allergy and a frequent eczema irritant. Removing added fragrance is one of the highest-value steps for eczema-prone and sensitive skin, so the more reliable label wording is the one they recommend.
How do I check a product is genuinely fragrance-free?
Read the ingredients list. There should be no parfum, fragrance or aroma, and no named fragrance allergens like limonene or linalool. If any of those appear, it is not truly fragrance-free, whatever the front of the pack says.
Are essential oils a safe alternative?
Not necessarily. Essential oils are still fragrance and contain natural fragrance allergens, so a product scented with them can flare eczema just as readily. For reactive skin, fragrance-free is the safer default.
Does fragrance-free mean no reactions at all?
No. Other ingredients such as certain preservatives can still cause problems for some people. Fragrance-free removes the most common single trigger, but patch testing a new product on a small area first is still wise.
