Reading Cosmetic Labelling Duties: What UK Law Requires

A guide to UK cosmetic labelling duties: what must appear on product packaging, who enforces it, and how to read labels for compliance.

The short answer

Beauty and wellness brands converge because they share the same references, the same template marketplaces, the same suppliers and the same fear of looking unprofessional. The result is a category where a customer can screenshot ten businesses and be unable to tell which is which. The cost is not aesthetic, it is commercial: when nothing distinguishes you visually or verbally, the only remaining variable is price. Leaving the convergence does not require strangeness. It requires committing to one specific, ownable decision and holding it across every surface for long enough that people start to recognise it without being told.

UK cosmetic labels must meet strict rules covering ingredient listing, responsible person, batch number, warnings, and shelf life. These requirements, set by UK Cosmetics Regulation, help ensure product safety, transparency, and traceability. Failing to comply can lead to enforcement action, product withdrawal, or reputational risk.

Cosmetic products sold in the UK must comply with the UK Cosmetics Regulation (Schedule 34 of the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019). This regulation requires that certain information is present and legible on every cosmetic product’s packaging. The aim is to protect consumer safety, enable traceability, and ensure informed purchasing decisions.

  • Name and Address: The name and address of the Responsible Person (the legal entity accountable for product compliance) must appear on the label. This is usually the manufacturer, importer, or distributor.
  • Nominal Content: The net quantity of the product (by weight or volume) must be shown, except for packaging containing less than 5g or 5ml, single-use packs, or free samples.
  • Batch Number: A code for batch identification must be on the packaging or container, enabling traceability if issues arise.
  • Ingredients List: All ingredients must be listed using their INCI (International Nomenclature of Cosmetic Ingredients) names, in descending order of weight.
  • Warnings and Precautions: Any specific warnings required by regulation, or necessary for safe use, must be included.
  • Date of Minimum Durability or PAO: Either a ‘best before’ date or ‘Period After Opening’ symbol is required, depending on shelf life.
  • Product Function: If not obvious, a statement of the product’s intended use must be provided.

Failing to meet these requirements is a breach of trading standards and can result in enforcement action. The Trading Standards service is the main enforcer for cosmetic labelling in the UK.

How to Read a Cosmetic Label for Compliance

Reading a cosmetic label for compliance involves checking for each required element. A missing address, incomplete ingredients list, or absent warnings are all red flags. Labels should be clear, indelible, and easily legible. Ingredient lists are usually found on the outer packaging; if there is none, they must be on an enclosed leaflet or tag.

Label Element Must Appear Where? Common Issues
Name & Address Outer packaging & container Missing for imported goods
Nominal Content Outer packaging & container Omitted on small packs
Batch Number Outer packaging or container Rubbed off easily
Ingredients List Outer packaging (or leaflet/tag) INCI names not used
Warnings Outer packaging & container Generic, not specific
Durability Date/PAO Outer packaging & container Symbol missing

If any of these are missing or unclear, the product may not be legally compliant. Always check for the ‘open jar’ symbol (PAO) for products with a shelf life over 30 months, or a ‘best before’ date for those under 30 months.

Who Is the Responsible Person and What Does That Mean?

The Responsible Person (RP) is the individual or company legally accountable for the cosmetic product in the UK market. They ensure that the product meets all regulatory requirements, including labelling, safety assessments, and notification to the UK Office for Product Safety and Standards (OPSS).

  • If manufactured in the UK, the brand owner is usually the RP.
  • If imported, the importer (based in the UK) is the RP.
  • Only one RP can be named per product, and their contact details must be on the label.

The RP must keep a Product Information File (PIF) available for inspection. If a product is found non-compliant, enforcement action is taken against the RP.

Ingredient Listing: How Must Ingredients Be Declared?

Ingredients must be listed in descending order of weight as they are added to the product, using INCI names. Certain ingredients, such as allergens, must be highlighted if present above specified thresholds. Fragrance and flavour compositions can be labelled as ‘parfum’ or ‘aroma’, but individual allergens from these must still be listed if required.

  • Colourants: Listed after other ingredients, using Colour Index numbers (e.g. CI 77491).
  • Ingredients under 1%: Can appear in any order after those over 1%.
  • Nanomaterials: Must be indicated with ‘[nano]’ after the name.

Allergen disclosure is required for certain substances in leave-on and rinse-off products, as specified in Annex III of the regulation.

Warnings, Precautions, and Shelf Life: What Must Be Stated?

Some products require specific warning statements, such as those containing certain essential oils, hair dyes, or sunscreens. The exact wording can be prescribed by regulation or safety assessment. Shelf life is indicated by:

  • ‘Best before’ date: For products with a shelf life of less than 30 months.
  • ‘Period After Opening’ (PAO) symbol: For products stable for more than 30 months, showing how long it can be safely used after opening.

Warnings must be easy to find and understand. If space is limited, warnings can be provided on a leaflet, with a ‘hand and book’ symbol on pack to indicate this.

Decision Rule: Is This Cosmetic Label Compliant?

Check If Yes If No
Responsible Person named with UK address? Pass Non-compliant
Ingredient list using INCI names? Pass Non-compliant
Batch number present? Pass Non-compliant
Net content stated? Pass Check size exemption
Warnings as required? Pass Non-compliant
Shelf life/PAO shown? Pass Non-compliant

If all checks pass, the label is likely compliant. Any failure means the label does not meet UK legal requirements and may risk enforcement action.

Enforcement and Penalties for Non-Compliance

Trading Standards is the principal enforcer of cosmetic labelling in the UK. If a product is found to be non-compliant, possible actions include product withdrawal, recall, or prosecution. In some cases, the Office for Product Safety and Standards (OPSS) may also become involved. Non-compliance can damage brand reputation and may result in financial penalties.

  • Enforcement typically starts with advice or a warning.
  • Persistent or serious breaches can lead to seizure of goods or prosecution.
  • Penalties depend on the nature and severity of the breach.

It is advisable to review packaging regularly, especially after regulatory changes or Brexit-related updates.

Limits of This Guidance

This guidance does not cover medical devices, biocides, or products regulated as medicines. It applies only to finished cosmetic products intended for sale in the UK. It does not address products sold in the European Union, where labelling duties may differ. Businesses selling outside the UK must check local requirements. This is not legal advice; consult a regulatory specialist for complex cases.

Questions readers ask

Do UK labelling rules apply to online-only cosmetic brands?

Yes. Products sold online to UK consumers must meet the same labelling requirements as those sold in physical shops, including all mandatory information on the product and packaging.

What happens if my ingredient list uses non-INCI names?

Using non-INCI names is a breach of UK labelling rules. This can result in enforcement action, product withdrawal, or reputational harm. INCI names are required for ingredient transparency and consistency.

Do testers and samples need full labelling?

Free samples and single-use testers are exempt from some requirements, such as nominal content. However, information on ingredients and warnings must still be made available to consumers, often via leaflet or tag.

Is the Responsible Person always the manufacturer?

Not always. The Responsible Person is the UK-based entity responsible for compliance. For imported products, it is usually the importer, not the overseas manufacturer.

How do I show shelf life on a cosmetic product?

Show a ‘best before’ date for products with a shelf life under 30 months. For those over 30 months, use the Period After Opening (PAO) symbol, indicating how long the product is safe to use after opening.

Are allergens always listed on the label?

Certain fragrance allergens must be listed if present above regulatory thresholds, as specified in Annex III of the UK Cosmetics Regulation. This applies to both leave-on and rinse-off products.

Can warnings be provided only online?

No. Required warnings must appear on the product packaging or, if space is limited, on a leaflet or tag accompanying the product. Online listings do not replace on-pack requirements.

Questions we get asked

Is it risky to look very different from everyone else in my area?

The risk is real but it is usually misdiagnosed. Being visually distinct is low risk if the underlying service is conventional and well executed. It becomes risky when the distinctiveness extends to things clients rely on for reassurance, such as clarity about what a treatment involves, who is performing it and what it costs. Be adventurous with identity, conservative with information.

How long before a distinctive identity starts to pay?

There is no reliable published figure for this and we will not invent one. What we can say about the mechanism is that recognition builds through repeated exposure, so the timeline is a function of how often your audience sees you rather than how many months pass. A business with a large repeat client base and steady social output accumulates recognition faster than one relying on infrequent visits.

Should I hire a designer or use a template?

A template is fine for the parts of the business where being ordinary costs nothing, such as an appointment reminder layout. It is a poor choice for the small set of assets that are supposed to make you recognisable, because the whole value of those assets is that other businesses do not have them. Spend where distinctiveness is the point and save where it is not.

Does any of this matter if most of my bookings come from walk-ins and word of mouth?

It matters more, not less. Word of mouth requires the recommender to be able to describe you. A business with no describable characteristics generates recommendations for the treatment rather than for itself, and those recommendations are then captured by whoever the person searching finds first.

Can I own a colour?

Not legally, in any general sense. Colour trade marks are difficult, rare and usually require extensive evidence of acquired distinctiveness. In practical terms you can become associated with a colour through consistent use, which is worth doing, but treat it as a marketing asset rather than a property right. The Intellectual Property Office publishes guidance on what can and cannot be registered.
