How to find skincare products without an ingredient

How to check a product before buying

1. 1Identify what you need to exclude. If reactions keep happening and you cannot identify the cause, a dermatologist can use medical patch testing to help find the allergen.
2. 2Write down the ingredient name and any alternative names relevant to your allergy. For example, rosin is also called colophony, and lanolin is an example of wool alcohol.
3. 3Check the ingredient list on the product packaging against those names. For fragrance, also look for parfum or aroma, which can represent perfume or aromatic mixtures.
4. 4Reject products containing your identified allergen. Use a fragrance free label to narrow fragrance choices, but remain cautious about unscented products and botanical ingredients.

An ingredient list is more useful here than a product name, however hard the name is working.1

Does unscented mean fragrance free?

No. Unscented products can contain fragrance materials that mask the smell of other ingredients. Products labelled fragrance free or without perfume generally do not contain fragrances or masking scents. Unscented describes the smell, which is not quite the ingredient check it sounds like.2

On EU labels, certain fragrance allergens must be named individually above specified concentrations: 0.001% in products left on the skin and 0.01% in products rinsed off. A missing individual name therefore does not settle whether that fragrance allergen is present below the labelling threshold. If you need to avoid a particular fragrance allergen, check both the individually listed ingredients and the fragrance claim.1

EU rules now require individual labelling of 56 additional fragrance allergens. Products placed on the market before 31 July 2026 can remain available until 31 July 2028 under the transition rules, so packaging can still reflect different labelling requirements. More fragrance names on a label do not automatically mean a product is unsafe; the names help people with specific allergies avoid their triggers.1

Do you need to avoid a whole ingredient category?

Start with the identified trigger rather than assuming every preservative or fragrance ingredient causes the same problem. Preservatives can cause cosmetic allergy, but antimicrobial preservatives also prevent bacterial or fungal growth in cosmetics containing water. An allergen can be harmless to people who are not allergic to it, while tiny quantities can trigger dermatitis in someone who is.24

In the US, cosmetics and their ingredients generally do not need FDA approval before sale, apart from certain colour additives. FDA approval is not a shortcut for finding a product without your ingredient.5

How to test a new product

For a new product you have screened, test it before adding it to your routine.

1. 1Apply your normal amount to a spot about the size of a quarter on the underside of your arm or elbow bend, twice daily for seven to 10 days.
2. 2Leave it on for the usual duration. For a cleanser, use five minutes or the duration in its instructions.
3. 3If there is no reaction after seven to 10 days, begin using the product. Home testing helps predict a reaction; medical patch testing identifies an allergy.

What if your skin still reacts?

Wash the product off gently and stop using it if a reaction develops. A cool compress or petroleum jelly can help; see a dermatologist if the reaction is severe and those measures do not relieve it. Repeated or persistent symptoms warrant assessment for contact allergy. Avoiding the identified cause should improve contact dermatitis and can allow it to clear completely.346
