A cosmetic label does more than identify a product. It communicates what the product is, what it contains, how it should be used and what consumers can reasonably expect it to do. That makes cosmetic labelling requirements and claims compliance a critical part of bringing a beauty product to market. A product may have a compliant formulation and a completed safety assessment, but the brand can still face problems if its packaging or marketing claims are misleading, unsupported or inconsistent with the evidence available for the finished product.
This is particularly important for modern beauty brands. Claims such as “clinically proven”, “deeply hydrating”, “anti-ageing”, “hypoallergenic”, “non-toxic”, “chemical-free” or “dermatologist approved” can influence purchasing decisions, but the wording needs to be considered carefully.
Under the EU Cosmetics Regulation, cosmetic claims must not imply characteristics or functions that the product does not have. The common criteria for cosmetic claims include legal compliance, truthfulness, evidential support, honesty, fairness and informed decision-making.
In Great Britain, the Responsible Person must ensure that cosmetic claims are correct and that the product’s packaging and marketing do not make unsupported or misleading claims.
The practical question for brands is therefore not simply, “Can we put this claim on the label?”
It is:
“Can we legally make this claim, and can we demonstrate that the finished product delivers what the claim promises?”
What Are the Main Cosmetic Labelling Requirements?
Before looking at claims, brands need to get the basic label requirements right.
For cosmetic products in Great Britain, required information includes details such as the Responsible Person, country of origin where applicable, nominal quantity, durability information, precautions, batch or identification information, product function and ingredients. The information must be clear and easy to read.
The EU Cosmetics Regulation similarly establishes mandatory labelling requirements for cosmetic products, including Responsible Person information, nominal content, durability information, precautions, product function and ingredient information, subject to applicable exceptions.

Key Takeaways
- Cosmetic labels must provide required information clearly, accurately and in the prescribed format.
- Cosmetic claims must not imply that a product has characteristics or functions that it does not have.
- Claims need appropriate, adequate and verifiable evidence to support the benefit being communicated.
- Ingredient properties should not automatically be presented as proven benefits of the finished cosmetic product without supporting evidence.
- Terms such as “clinically proven”, “hypoallergenic”, “free from” and “dermatologically tested” can require careful substantiation depending on how they are used.
- Claims can appear on packaging, websites, social media, advertisements, product names and other marketing materials, so compliance cannot be limited to the physical label.
- The Responsible Person has an important role in ensuring cosmetic claims and product information meet applicable requirements.
- A structured claims review process can help brands reduce regulatory risk before products reach the market.
A Practical Label Checklist
Before artwork is approved, brands should check:
- Product name and function
- Responsible Person name and address
- Nominal quantity
- Date of minimum durability or PAO, where applicable
- Precautions and warnings
- Batch or identification number
- Country of origin where required
- Ingredient list
- Required symbols
- Appropriate language requirements
- Claims and product descriptions
- Legibility of mandatory information
The label should also be consistent with the product’s supporting documentation.
A claim should not appear on the packaging simply because it sounds commercially attractive. There should be a clear regulatory and evidential basis for using it.
What Makes a Cosmetic Claim Legally Defensible?
A legally defensible cosmetic claim should accurately communicate the characteristics or benefits of the product and be supported by appropriate evidence.
The EU common criteria provide a useful framework for assessing claims.
- Legal Compliance
Claims must comply with applicable legislation and should not suggest that a cosmetic has received regulatory approval simply because it complies with mandatory legal requirements.
For example, a claim such as “EU approved cosmetic” can create a misleading impression because cosmetics are not generally marketed on the basis of an EU pre-market approval of the finished product.
Similarly, describing a product as “legally compliant” is not necessarily a meaningful consumer benefit. Compliance with mandatory requirements is an obligation, not a unique product advantage.
- Truthfulness
A claim should accurately reflect the product.
If a label says that a product contains a particular ingredient, that ingredient should actually be intentionally present.
More importantly, a brand should not automatically transfer a known property of an ingredient to the finished formulation without evidence that the finished product provides the claimed benefit.
For example:
Ingredient fact:
“Contains hyaluronic acid.”
Performance claim:
“Reduces the appearance of fine lines.”
These are different claims and may require different supporting evidence.
- Evidential Support
Claims need appropriate and verifiable evidence.
The evidence should relate to the product and the benefit being claimed. The strength of evidence should also be appropriate to the nature of the claim.
A laboratory result demonstrating the properties of an ingredient does not automatically prove that the finished cosmetic produces the same effect.
Brands should therefore ask:
- What exactly are we claiming?
- What evidence supports the claim?
- Does the evidence relate to the finished product?
- Is the study method appropriate?
- Is the evidence current?
- Does the evidence support the exact wording being used?
Defensible Claims vs Risky Claims
The wording of a claim can make a significant difference.
| Claim Type | Example | Compliance Consideration |
| Ingredient claim | “Contains vitamin C” | Should accurately reflect the formulation |
| Moisturising claim | “Helps moisturise skin” | Should be supported by appropriate evidence |
| Appearance claim | “Helps reduce the appearance of fine lines” | Evidence should support the stated cosmetic benefit |
| Testing claim | “Dermatologically tested” | Testing should actually have been conducted and support the wording |
| Performance claim | “Provides 24-hour hydration” | Requires evidence supporting the duration |
| Absolute claim | “Eliminates wrinkles” | Higher risk if evidence cannot support the absolute outcome |
| Medical-style claim | “Treats eczema” | May raise classification and medicines-related concerns |
| Regulatory claim | “EU approved” | Can create a misleading impression of regulatory approval |
The objective is not to eliminate strong marketing language.
It is to make sure the strength of the language is proportionate to the evidence.
Claims That Often Need Extra Scrutiny
Certain types of claims can create additional regulatory risk because consumers may interpret them as stronger guarantees than the available evidence supports.
“Clinically Proven”
This wording can imply a significant level of clinical evidence.
If used, the brand should be able to demonstrate what was tested, how it was tested, who participated, what outcome was measured and whether the study supports the exact claim.
“Dermatologically Tested”
This does not automatically mean that dermatologists have confirmed that a product is effective or suitable for everyone.
The wording should accurately reflect what testing was conducted and what the test actually demonstrated.
“Hypoallergenic”
This is a particularly sensitive claim because consumers may interpret it as meaning that the product cannot cause an allergic reaction.
A brand needs appropriate evidence and should avoid communicating an absolute guarantee that cannot be supported.
“Free From”
“Free from” claims need to be considered in context.
A claim can be problematic if it is misleading, implies an irrelevant advantage or unfairly suggests that legally permitted ingredients are inherently unsafe.
The European Commission’s technical guidance specifically addresses “free from” claims under the common criteria framework.
“Non-Toxic”
“Non-toxic” can create an extremely broad consumer expectation.
A cosmetic formulation may be considered safe when used as intended without that meaning that the product can reasonably be described as universally “non-toxic” in every circumstance.
Claims should therefore be precise rather than making unnecessarily broad safety promises.
Cosmetic Claims Are Not Limited to the Packaging
One of the most common compliance mistakes is treating claims review as an artwork-only exercise.
A cosmetic claim can appear across the entire customer journey.
This can include:
- Product packaging
- Product names
- Websites
- Product descriptions
- Amazon and marketplace listings
- Social media
- Influencer content
- Digital advertising
- Brochures
- Retailer descriptions
- Point-of-sale materials
- Videos
- Before-and-after imagery
A compliant statement on the physical packaging does not protect a brand from an unsupported claim made elsewhere.
This is why claims governance needs to cover the complete marketing ecosystem.
When Can a Cosmetic Claim Become a Legal Problem?
A claim becomes particularly risky when it creates a consumer expectation that the evidence cannot support.
For example, consider:
“Reduces wrinkles in 7 days.”
This is a specific performance claim with a defined outcome and timeframe.
A brand should be able to demonstrate that the finished product produces the claimed result within that timeframe under the conditions represented to consumers.
Compare this with:
“Helps improve the appearance of fine lines.”
This is still a performance claim and needs appropriate support, but the consumer expectation is different.
The lesson is simple:
The more specific the promise, the more specific the supporting evidence needs to be.
Claims and the Cosmetic Product Safety Report
Claims compliance should not be treated as completely separate from the wider product compliance file.
The Product Information File and Cosmetic Product Safety Report provide important evidence about the product and its safety.
However, a safety assessment does not automatically substantiate every marketing claim.
For example, a CPSR may establish that a product is safe for its intended use. That does not automatically prove that the product:
- Reduces wrinkles
- Increases collagen
- Provides 72-hour hydration
- Repairs damaged skin
- Removes pigmentation
- Improves elasticity
Those are performance or consumer benefit claims that may require additional supporting evidence.
This distinction is important when preparing product artwork and marketing materials.
What Evidence Can Support Cosmetic Claims?
The appropriate evidence depends on the claim.
Potential supporting evidence can include:
- Ingredient data
- Formulation information
- Laboratory testing
- Instrumental measurements
- Consumer perception studies
- Clinical or dermatological studies
- In-use testing
- Stability or performance testing
- Published scientific literature
- Supplier documentation
- Before-and-after assessments, where appropriately designed
The evidence should be relevant to the claim and sufficiently robust to support the wording used.
A supplier document about an ingredient should not automatically be treated as proof that the finished cosmetic provides the same benefit.
How to Build a Claims Substantiation File
A practical claims substantiation process can be built around five steps.
Step 1: Identify Every Claim
Collect claims from:
- Packaging
- Artwork
- Website
- Product listings
- Advertising
- Social media
- Influencer briefs
Step 2: Categorise the Claim
Determine whether the statement relates to:
- Ingredients
- Product performance
- Sensory properties
- Safety
- Testing
- Environmental characteristics
- Consumer experience
- Comparative performance
Step 3: Identify the Evidence
For each claim, identify the evidence that supports it.
Step 4: Check the Strength of the Wording
Ask whether the wording goes further than the evidence.
If the evidence demonstrates an improvement, avoid automatically turning that into an absolute claim of elimination or prevention.
Step 5: Approve the Final Claim
Only use the version that has passed the appropriate regulatory and evidential review.
This process can become particularly valuable when multiple teams are involved in product development, regulatory approval, marketing and design.
Common Cosmetic Labelling Mistakes
- Missing Mandatory Information
Even a strong marketing campaign cannot compensate for missing mandatory label information.
- Unsupported Performance Claims
Claims such as “clinically proven” or “24-hour protection” require evidence appropriate to the specific wording.
- Ingredient-to-Product Extrapolation
A known ingredient property does not automatically prove the same benefit for the finished formulation.
- Overstating Test Results
A test may demonstrate a particular result under specific conditions. Marketing language should not expand that result into a broader promise.
- Making Medical Claims
Statements suggesting that a cosmetic treats or prevents a disease can raise significant classification and regulatory concerns.
- Inconsistent Claims
The website may say one thing while the packaging says another.
Claims should be reviewed across all consumer-facing channels.
- Assuming “Natural” Means Safer
Natural-origin ingredients can still present safety, allergen or regulatory considerations. “Natural” should not be used to imply an unsupported safety advantage.
UK and EU Claims Compliance: Are the Rules the Same?
The UK and EU cosmetic frameworks share important similarities because both derive from the broader European cosmetic regulatory framework.
However, brands should not assume that one claims review automatically provides complete compliance across every market.
Great Britain operates under its own retained cosmetic legislation and enforcement framework, while Northern Ireland remains subject to the EU Cosmetics Regulation under the current arrangements.
For brands selling across the UK and EU, artwork, Responsible Person details, notification requirements and other market-specific elements should therefore be reviewed carefully.
This is particularly important when one packaging design is intended for multiple markets.
The Role of the Responsible Person
The Responsible Person has a central role in cosmetic compliance.
In Great Britain, the Responsible Person must ensure that the cosmetic product complies with applicable requirements and must be able to demonstrate that claims made when marketing the product are correct.
This means claims should not be treated as solely a marketing department responsibility.
Regulatory, product development, legal, marketing and design teams may all need to work together before a claim reaches consumers.
For international brands, a strong responsible person services model can help establish clearer ownership and review processes.
How Compliance Automation Can Reduce Claims Risk
As product portfolios expand, managing claims manually can become difficult.
Brands may have hundreds of product claims spread across packaging files, websites, retailer listings and marketing assets.
Compliance automation can help create greater visibility by allowing businesses to organise:
- Approved claims
- Supporting evidence
- Product versions
- Market-specific artwork
- Regulatory review status
- Expiry or review dates
- Responsible owners
- Supporting documentation
Automation does not replace regulatory assessment.
Instead, it can help ensure that approved information remains controlled and that teams are working from the correct version.
This can be particularly useful for brands launching products across multiple markets where the same product may require different regulatory information or claims treatment.

A Practical Cosmetic Labelling and Claims Checklist
Before approving cosmetic artwork or launching a marketing campaign, ask:
Product Information
- Is the product function clear?
- Is the Responsible Person information correct?
- Is the nominal quantity correct?
- Is the durability information appropriate?
- Are required precautions included?
- Is the batch or identification information present?
- Is the ingredient list accurate?
- Are required symbols included?
Claims
- What exactly does each claim promise?
- Is the claim truthful?
- Is the claim legally compliant?
- Is there evidence supporting it?
- Does the evidence relate to the finished product?
- Does the wording go beyond the evidence?
- Could consumers interpret the claim more broadly than intended?
- Is the claim consistent across packaging, website and advertising?
- Does the claim create a medical or therapeutic implication?
- Does the claim unfairly compare the product with competitors?
Evidence
- Is the supporting study appropriate?
- Is the evidence current?
- Can the evidence be verified?
- Are the test conditions clear?
- Does the evidence support the exact wording?
- Is the evidence stored and traceable?
If these questions cannot be answered confidently, the claim should be reviewed before publication.
Conclusion
Cosmetic labelling and claims are not simply marketing considerations. They are part of the wider regulatory responsibility of placing a cosmetic product on the market.
The strongest claims are not necessarily the most aggressive ones. They are the claims that accurately communicate the product’s characteristics and benefits while being supported by evidence appropriate to the promise being made.
For brands, the practical approach is to review labelling and claims together, maintain a clear evidence trail, involve the Responsible Person early and make sure the same approved claims are used consistently across packaging and marketing channels.
A structured review process can help identify risky wording before it reaches consumers, reducing the likelihood of costly artwork changes, retailer challenges or enforcement action.

Frequently Asked Questions
- What are the main cosmetic labelling requirements?
Depending on the market and applicable legislation, cosmetic labels generally need information such as the Responsible Person details, product quantity, durability information, precautions, batch or identification information, product function and ingredient list. Additional requirements may apply depending on the product and market.
- Do cosmetic claims need to be scientifically proven?
Cosmetic claims must be supported by evidence that is adequate and verifiable, with the level of evidence appropriate to the type of claim. The evidence should be relevant to the product and the benefit being claimed.
- Can a cosmetic brand use “clinically proven” on its packaging?
It may be possible where the claim is accurate and supported by appropriate evidence. However, the wording can create a strong consumer expectation, so brands should be able to demonstrate what was tested, how it was tested and how the results support the specific claim.
- Who is responsible for cosmetic claims compliance?
The Responsible Person has important legal responsibilities for cosmetic compliance. In Great Britain, the Responsible Person must be able to demonstrate that claims made when marketing the cosmetic product are correct.
