What Counts as a Cosmetic Product in the UK?

Before you start ordering fancy jars or batch-printing ingredient lists, it’s crucial to get clear on what UK law classifies as a “cosmetic product.” This might seem simple, but lines can blur between cosmetics and medicines - and the law treats them very differently.

• Cosmetic products are substances or mixtures intended to be applied to the skin, hair, nails, lips, external genital organs, teeth, or the mucous membranes of the mouth. Their main purpose is to clean, perfume, change appearance, protect, keep in good condition, or correct body odours.
• Examples include make-up, skincare creams, shampoos, hair dyes, deodorants, toothpaste, nail polish… the list goes on.

If your product claims to treat or prevent disease, or has a medical function, it could instead be classed as a medicine or medical device. This is a different (and far stricter) regulatory path - so if you’re in doubt, seek legal advice before launching.

Why Are Cosmetic Labelling Requirements So Important?

Cosmetic labelling is about more than just marketing - it’s central to consumer safety and legal compliance. UK laws are strict here because cosmetics are used directly on the body and can sometimes cause irritation, allergies, or worse if misused. Your label is the customer’s key source of information.

• Safety: Accurate labels prevent allergic reactions and inform on safe use.
• Transparency: Customers need to know exactly what they’re buying (and what’s in it).
• Legal protection: Meeting legal requirements protects you from liability claims, fines, and forced product withdrawal.

It’s your legal (and ethical) responsibility to ensure your products are properly labelled under UK law when selling cosmetics. Let’s break down exactly what’s required.

Which Cosmetic Labelling Laws and Regulations Apply in the UK?

Several laws spell out the rules for cosmetic labelling in Britain. The main ones include:

• UK Cosmetics Regulation (Schedule 34 of the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019) - This is the post-Brexit version of EU Regulation (EC) No 1223/2009. It sets out requirements on safety, labelling, claims and more.
• Consumer Protection Laws - Like the Consumer Rights Act 2015 and Consumer Protection from Unfair Trading Regulations 2008, which ban misleading claims and require correct product information.
• The Trade Marks Act 1994 - If you have a branded product, correct use of names and trade marks helps you avoid IP disputes and copycats. (Read more on brand protection.)

If you’re selling online, you’ll also need to follow e-commerce regulations and distance selling rules that relate to descriptions and advertising.

Who Is Responsible for Cosmetic Labelling Compliance?

In UK law, the “responsible person” for cosmetic labelling is usually the manufacturer or the first importer into the UK market. For many small brands, that’s you!

• If you’re making products here, you are the responsible person.
• If you import cosmetics from outside the UK (even the EU), you are responsible - not the overseas supplier.
• If you’re selling another UK brand’s products, the responsibility falls on the brand/primary distributor. However, as a retailer, you still need to check compliance or risk selling mislabelled products unlawfully.

The “responsible person” must make sure all products comply with the cosmetic labelling requirements uk before selling cosmetics to customers.

What Information Must My Cosmetic Labels Include?

The UK Cosmetics Regulation mandates that certain information appears either on the product container and/or the outer packaging (i.e. the box). Here’s the must-have list:

• Name and address of the responsible person - A full UK address (not just a website or PO Box).
• Nominal content - Net weight or volume (e.g. 50ml, 150g).
• Date of minimum durability (“best before”) or Period After Opening (PAO) - E.g. “Best before end: 12/2025” or the “open jar” symbol with a number of months (e.g., “12M” means 12 months).
• Precautions for use - Any safety directions or warnings, for example “For external use only” or “Keep away from eyes”.
• Batch number - Helps track products in case of safety issues or recalls.
• Product function - If it’s not obvious from the branding. (For example, “face moisturiser” or “lip balm”.)
• List of ingredients - Must follow the International Nomenclature of Cosmetic Ingredients (INCI) system and be listed in descending order of weight. Allergens must be clearly indicated.

If you sell very small products (like miniature lipsticks), some details can go on accompanying leaflets instead, but certain information must always be present on the container.

What If I’m Selling Cosmetics Online?

Online selling brings an extra layer of requirements. UK law demands “distance sellers” provide, before purchase, the same key product information as found on the label - typically on the product page or through downloadable information (like a PDF).

This includes:

• The full list of cosmetic ingredients.
• Safety warnings and usage instructions.
• Details of the responsible person/company.

Extra Traps: Claims, Allergens, and Special Ingredients

Beyond the basics, here are some common areas where cosmetic sellers slip up:

• Misleading claims: Never claim your product can heal, treat or prevent disease unless you’re licensed (then it’s a medicine, not a cosmetic!). All claims must be truthful and backed by evidence.
• Allergens and “free from” claims: If you state a product is “allergen free” or includes certain “natural” or “organic” claims, you’ll need to make sure these are accurate. Labelling mistakes here are a top cause for legal complaints.
• Novel ingredients: Using untested or banned ingredients can land you in hot water. Always check the current UK Cosmetics prohibited/restricted substances list before formulating or importing a product.

It’s wise to review your product descriptions and advertising to stay within the law - and consult a legal expert if you're unsure about a specific claim or formulation.

Are There Additional Legal Requirements for Selling Cosmetics?

Absolutely. The label is just one compliance step when you’re selling cosmetics. Don’t forget these other legal must-haves:

• Safety assessments: Every cosmetic product must undergo a safety assessment by a qualified professional before sale (“Cosmetic Product Safety Report” or CPSR).
• Notification: Products must be notified to the UK Office for Product Safety and Standards (OPSS) before being placed on the UK market.
• Data protection: If you collect and store customer details (especially online), you’re subject to UK GDPR rules. You’ll need a compliant Privacy Policy and secure systems.
• Contracts and T&Cs: Don’t forget to have clear terms and conditions, returns policies, and supplier agreements in place. These protect your business from disputes and provide clarity for buyers.

Do I Need to Register My Cosmetics Business?

Yes, if you’re starting a cosmetics business in the UK, you must operate using a legal structure. Most sellers set up as a sole trader, limited company, or partnership. Each has its own advantages and tax implications.

If you’re unsure which route is right for your venture, our guide to choosing a business structure explains the basics - but always seek bespoke legal advice before registering.

How Can I Make Sure My Cosmetic Labels and Business Are Legally Protected?

Getting the legal side right when selling cosmetics can be overwhelming, but it doesn’t have to be. Here’s how to stay protected from day one:

• Stay up-to-date: Cosmetic labelling regulations and ingredient lists change from time to time (especially after Brexit). Monitor legislation via GOV.UK or chat to a lawyer for the latest updates.
• Get documents drafted by a professional: Avoid DIY or cheap online templates for your contracts, website T&Cs, and privacy notices. Legal documents need to fit your business and compliance needs exactly.
• Don’t neglect the details: Small mistakes (like a missing allergen, or an outdated address) can still result in enforcement action, especially if a customer suffers harm.

If you’re feeling unsure or want to avoid common pitfalls, working with a legal expert is a smart move. The right advice now can save you big headaches (and costs) later.
