How to use this aesthetics claims evidence register
Aesthetics advertising is not assessed only by whether a treatment is commonly offered. The published wording, image, audience, medium and surrounding context all affect whether a claim can be supported. This register is a pre-publication reference for businesses making claims about cosmetic procedures, devices, injectables, skin treatments and retail products in the UK.
Start with the exact claim a prospective client will see, rather than an internal description of the service. Then identify the claim category in the register, collect the listed supporting material, apply the stated qualification, and retain a source record. A treatment page may contain several claim categories at once: a factual description, a result promise, a safety implication and a before-and-after image each need separate checks.
The main advertising standard is the CAP Code, enforced in non-broadcast advertising by the Advertising Standards Authority. The Committee of Advertising Practice publishes guidance and advice, but its materials do not remove the need to consider the particular execution. Where a claim crosses into medicines, medical devices, professional regulation or cosmetic product compliance, another regulator or legal framework may also matter.
This is a working register, not a collection of approved phrases. A phrase can be accurate in one context and misleading in another if it overstates expected outcomes, omits a material limitation, uses unrepresentative imagery or implies medical status that cannot be substantiated. Keep the published version alongside the evidence relied upon, so that the business can explain its decision if challenged.
Publication rule: if the claim needs a qualification to be accurate, the qualification must be clear, prominent and close enough to the claim to be read with it.
The related Digital Gloss pages on advertising rules, reviews and before-and-after images, and reading cosmetic labelling duties provide subject-specific context. This register is the cross-check to use when one campaign contains several of those issues.
The evidence register: treatment, outcome and safety claims
The table below is the central reference asset. "Verify in" identifies a named body, document or record a business can inspect before publication. It does not mean that a single document automatically proves every formulation of a claim. The advertiser remains responsible for substantiation before the advertisement appears.
| Claim category | Evidence to hold | Qualification and publication check | Verify in |
|---|---|---|---|
| General treatment description | Accurate description of what is done, by whom and with what product or device. | Do not turn a procedure description into an outcome guarantee. Check that titles and captions match the consultation process. | CAP Code and the business's treatment protocol. |
| Visible result or improvement | Robust evidence relevant to the stated outcome, treatment, population and conditions of use. | Avoid absolute, universal or permanent wording unless it is supported. State material limits where needed. | CAP Code rule on substantiation and relevant CAP guidance. |
| Speed of result | Evidence for the stated timescale and a record of the treatment schedule. | Separate an early possible effect from the usual endpoint. Do not imply immediate results where assessment takes longer. | CAP guidance on health and beauty claims and clinical source material. |
| Safety, painless or risk-free | Evidence for the precise safety statement and documented risk information. | Do not minimise material risks or use "risk-free". "Painless" requires particular care because experience varies. | CAP Code, treatment consent materials and relevant professional guidance. |
| Medical or clinical efficacy | Appropriate clinical evidence for the exact medical implication. | Do not imply diagnosis, prevention or treatment of disease unless the legal and evidential position permits it. | CAP Code section on medicines, medical devices, health-related products and beauty products; Medicines and Healthcare products Regulatory Agency materials where applicable. |
| Device performance | Manufacturer documentation, intended purpose, instructions and evidence supporting the advertised use. | Do not advertise beyond the device's intended purpose or imply a regulatory endorsement that does not exist. | Medicines and Healthcare products Regulatory Agency guidance and the device documentation. |
| Longevity or permanence | Evidence for duration, conditions and variability of the claimed effect. | Specify whether the wording concerns a possible, average or expected duration. Avoid permanence claims without clear support. | CAP Code substantiation requirement and treatment evidence file. |
For all rows, retain the date checked, version of the advert, source title, source date where available, and the person who approved publication. A supplier brochure alone may not resolve whether the final consumer-facing claim is adequately supported.
Testimonials, reviews and before-and-after material
Testimonials can describe an individual's experience, but they do not automatically substantiate a general claim about likely results. If a review says a treatment "removed" a condition, "fixed" a medical problem or produced a result for everyone, reproducing it in marketing can adopt that message as the advertiser's own. The same principle applies when a business reposts client content, adds a caption or selects a testimonial for a campaign.
Before-and-after material needs a traceable record. Keep the original image files where possible, the date each image was taken, confirmation that the images portray the same person, the treatment undertaken, any other relevant interventions, and the client's documented permission for the intended use. Check lighting, angle, distance, pose, facial expression, make-up, hair, tanning, editing and image compression. These variables can materially change apparent results.
| Material | Evidence record | Key publication check | Verify in |
|---|---|---|---|
| Client testimonial | Original review, date, identity trail held securely and permission where the content is reused. | It must be genuine, representative in context and not presented as typical without support. | ASA guidance on testimonials and endorsements; CAP Code rules on misleading advertising. |
| Before-and-after image | Originals, treatment record, image conditions and consent record. | Do not use editing or presentation that exaggerates the outcome. Explain material timing or treatment differences. | ASA guidance and rulings concerning before-and-after advertising. |
| Creator or client post | Written agreement defining the post, disclosure, permissions and retained copy. | Commercial intent must be identifiable where required. The advertiser remains responsible for claims it controls. | CAP guidance on influencer marketing and the ASA's published guidance. |
Do not use a consent form as an evidential substitute. Consent may address permission to publish an image, while substantiation addresses whether the image and accompanying text create a misleading impression. The dedicated Digital Gloss reference on reviews, testimonials and before-and-after images should be used alongside this row-level check.
Medicinal, prescription and professional-status claims
The most consequential wording check is whether marketing presents a cosmetic or aesthetic service as diagnosing, preventing or treating disease, or otherwise makes a medicinal claim. A business may use clinical language internally or during an appropriately managed consultation, but public advertising has separate constraints. The claim, not simply the treatment name, determines the risk.
Prescription-only medicines must not be advertised to the public. A clinic should therefore audit not only product names but indirect promotional devices: invitations to request a named prescription medicine, result-led captions attached to it, product pack images, special offers and comparison claims can all create problems. Product availability through a qualified prescriber does not convert public promotion into permitted advertising.
Professional credentials also require precision. A qualification, registration or membership should be stated exactly as it appears in the relevant register or certificate, with no implication that a regulator has endorsed the business, its result claims or a particular treatment. If a practitioner is subject to a professional regulator, inspect that regulator's current standards as part of the source check.
| Wording signal | Pre-publication decision | Verify in |
|---|---|---|
| "Treats", "cures", "heals" or disease naming | Pause publication and assess whether the wording makes a medicinal or disease-treatment claim. | CAP Code section on medicines, medical devices, health-related products and beauty products; Medicines and Healthcare products Regulatory Agency guidance. |
| Named prescription-only medicine | Do not use in public-facing advertising promoting a prescription-only medicine. | CAP Code rule on prescription-only medicines and Medicines and Healthcare products Regulatory Agency materials. |
| "Medical-grade", "clinically proven" or "doctor approved" | Define the exact proposition and obtain evidence for that proposition, not a general reputation claim. | CAP Code substantiation rules and the underlying study or professional record. |
| Professional title or registration | Use the exact title and check the current register or certificate. | The relevant statutory or professional register and applicable professional standards. |
Where there is uncertainty, obtain specialist advice before publication. Changing "treats" to a softer word may not solve the problem if the overall presentation still communicates a medical outcome.
Cosmetic products, ingredients and environmental language
Retail products used or sold by aesthetics businesses create a second evidence trail. Cosmetic claims must be supportable and consistent with the product's function, composition and product information. A product page, shelf talker, consultation leaflet and social caption can all make claims, including claims introduced by a retailer rather than the manufacturer.
Ingredient-led claims require special care. Naming an ingredient does not itself establish a finished product benefit at the concentration and formulation used. "Contains" may be a factual statement if accurate, but "works because it contains" is an efficacy proposition requiring support. Claims such as "natural", "clean", "non-toxic" and "chemical-free" can carry broad associations that exceed their literal wording. The existing Digital Gloss guide to cosmetic labelling duties is the appropriate companion for label-specific checks.
Environmental claims should identify the aspect being claimed. A statement about packaging, recycled content, refillability, sourcing or disposal should not become an unqualified claim that the whole product or business is environmentally beneficial. The Competition and Markets Authority's Green Claims Code sets out principles for environmental claims, while the ASA applies advertising rules to environmental messaging.
| Claim type | Evidence and record | Qualification check | Verify in |
|---|---|---|---|
| Ingredient benefit | Evidence tied to the finished product and advertised effect. | Check dose, formulation, route of use and consumer-relevant outcome. | Product information file and cosmetic claims support materials. |
| "Clean" or "natural" | Defined internal meaning and evidence for any explicit associated benefit. | Do not imply safety, purity or environmental superiority without support. | CAP guidance on cosmetics and beauty products; product documentation. |
| "Cruelty-free" | Documented basis for the exact claim across relevant supply arrangements. | Avoid a broader animal-testing implication than the evidence supports. | CAP guidance and the business's supply-chain documentation. |
| Environmental benefit | Specific, current evidence for the stated product or packaging attribute. | State limits and avoid whole-life implications where only one element is evidenced. | Competition and Markets Authority Green Claims Code and ASA environmental claims guidance. |
A screenshot decision rule before any claim goes live
Use this rule for a website edit, a reception poster, a reel caption, an email, a paid placement or a creator brief. It is deliberately stricter than asking whether the wording sounds reasonable. The business needs to establish what an ordinary member of the intended audience is likely to take from the complete execution.
- Write the claim exactly. Include headline, caption, image text, spoken words, hashtags and any testimonial selected for publication.
- Identify the takeaway. Ask what result, safety level, urgency, clinical status, professional endorsement or environmental benefit the audience is likely to infer.
- Classify the claim. Use the register row for result, safety, medical, device, testimonial, professional status, cosmetic or environmental wording.
- Match evidence to the takeaway. Check that the source concerns the same treatment or product, audience, outcome and conditions. A nearby proposition is not necessarily enough.
- Test the qualification. Put limitations close to the claim, in readable wording and in the same medium. Do not rely on a distant page or an inaccessible footnote.
- Check prohibited or restricted territory. Flag prescription-only medicine references, disease claims, unsupported medical implications and any regulated-device statement beyond intended purpose.
- Archive the decision. Save the final creative, evidence, source check, approvals and publication date together.
If any step cannot be completed, remove or rewrite the claim until it can. Do not fill a gap with a disclaimer that contradicts the headline. The CAP Code requires marketing communications to be prepared with a sense of responsibility to consumers and society, and the ASA can assess the overall impression rather than isolated words.
Source trail, review method and boundaries of this register
This register is built around primary UK advertising and regulatory sources: the CAP Code and CAP guidance, ASA published rulings and guidance, Medicines and Healthcare products Regulatory Agency material, and the Competition and Markets Authority's Green Claims Code. Product-specific records, treatment protocols, consent records and original image files are included because an external rulebook cannot prove what happened in an individual business.
For each campaign, record the source version checked and the date. Rules, guidance and regulator interpretations can change, while an ASA ruling may clarify how a principle applies to a new format. A maintained internal register should therefore have an owner, a scheduled review process and a trigger review after an upheld ruling relevant to the business's claim type, a new treatment launch, a product reformulation, or a change in advertising format.
This reference does not decide whether a treatment is clinically appropriate for a particular person, whether consent is valid, whether a product is legally placed on the market, or whether a practitioner is permitted to undertake a procedure. It does not replace advice on contracts, data protection, intellectual property, product safety or tax. It is not written for advertising directed outside the UK, where rules and enforcement routes differ.
It also does not apply a single evidence threshold to every statement. A mundane factual statement may need a business record; a strong efficacy, safety or medical implication can require far more rigorous substantiation. The safe operational distinction is simple: the more consequential the consumer takeaway, the more exact the evidence and qualification need to be.
For wider category context, consult the Digital Gloss claims hub. For a proposed advertisement involving a high-risk medical implication, a prescription-only medicine, a vulnerable audience or uncertainty about device status, pause publication and seek appropriately qualified advice.
Questions readers ask
What evidence is needed for an aesthetics advertising claim?
The evidence must support the exact consumer takeaway, not merely a related treatment or product fact. Keep records showing the treatment, product, claimed outcome, intended audience and conditions of use. Strong claims about efficacy, speed, safety, permanence or medical benefit need especially careful substantiation under the CAP Code.
Can a clinic use a client's review in an advert?
A genuine review may be used, but the business should retain the original, verify the wording and consider the message it communicates. A single client's account does not prove that others should expect the same outcome. Reposting a review can make its claims part of the advertiser's marketing communication.
Are before-and-after photographs sufficient evidence of results?
No. They can illustrate an outcome, but do not by themselves substantiate a general efficacy claim. Retain originals, dates, treatment details, consent and image-condition records. Check whether lighting, angle, pose, editing, make-up or timing could create a misleading impression of the scale or typicality of change.
Can aesthetics businesses advertise prescription-only medicines?
Prescription-only medicines must not be advertised to the public. Businesses should check names, images, captions, offers and indirect result claims, not just formal product advertisements. The relevant CAP Code rule and Medicines and Healthcare products Regulatory Agency materials should be checked before publishing related content.
Does 'clinically proven' need a study?
It needs evidence capable of supporting the precise impression created. That will often require robust clinical evidence, but the required assessment depends on what the advertisement says. Evidence about an ingredient, different formulation, different population or different endpoint may not support the final consumer-facing claim.
What makes a green claim misleading in aesthetics marketing?
A green claim can mislead when it is vague, omits important limits or implies a benefit for the whole product or business when evidence concerns only one feature. Specify the attribute, such as a packaging component or disposal route, and check the Competition and Markets Authority's Green Claims Code alongside ASA guidance.
How long should a business keep claims evidence?
Keep it for as long as the claim is live and long enough to answer a later challenge or review. Retain the final advertisement, evidence relied upon, source version, approval record and publication date together. Review the file when the treatment, formulation, claim wording or relevant guidance changes.
