EU Fragrance-Allergen Labels Are Expanding: How to Read a Longer Ingredient List

The direct answer: more named ingredients are a transparency change

European Union Regulation 2023/1545 expands the fragrance allergens that must be declared individually in the cosmetic ingredient list above specified concentrations. Across the listed substances, the familiar disclosure thresholds are more than 0.001% in leave-on products and more than 0.01% in rinse-off products. The rule is intended to help people who already know they are sensitised identify ingredients they may need to avoid. A longer ingredient list after the transition does not automatically mean the formula contains more fragrance, has changed, is more dangerous or will irritate every person. It may reflect more specific naming of components previously covered by a broader fragrance term.

The transition dates explain why labels may differ

The regulation was adopted on 26 July 2023 and provides transition periods. Products that do not comply with the new restrictions could be placed on the European Union market until 31 July 2026 and may remain available on that market until 31 July 2028. Therefore, during the transition, two legitimate packages of the same product family can display different ingredient wording depending on manufacturing date, reformulation, territory and stock movement. Those dates apply to the EU market. They do not establish Hong Kong labelling law, prove that a particular imported unit is compliant, or tell you whether a product is currently sold by A New You.

Fragrance allergy is specific; “sensitive skin” is broader

The EU Scientific Committee on Consumer Safety explained that contact allergy can be lifelong and that ingredient information helps sensitised people avoid allergens. It identified a wider set of established fragrance allergens than the older label list. However, stinging, dryness, acne, dislike of scent and allergic contact dermatitis are not interchangeable. A product described as natural, botanical, clean or essential-oil based can still contain fragrance allergens. Conversely, seeing a listed allergen does not mean every user will react. If repeated eczema-like reactions suggest contact allergy, a dermatologist can determine whether medical assessment and formal patch testing are appropriate; a cosmetic home patch test is not the same examination.

Use a repeatable label-reading method

Check the exact product, territory and current package rather than relying on an old web image. Photograph the full ingredient list and batch information, then compare names with any allergens already identified by a clinician. Introduce one new leave-on product at a time, follow directions and stop if a significant reaction develops. Seek urgent care for breathing difficulty, facial or eye swelling or widespread severe symptoms; persistent, blistering, weeping or recurrent dermatitis needs medical assessment. A New You can help you organise product questions for a cosmetic consultation, but it cannot diagnose allergy, verify every imported label or guarantee that a product is suitable for you.
