TL;DR: An aesthetic clinic can promise what it can prove and what it controls: a consultation with a named, qualified doctor, a clear explanation of the treatment and its risks, and honest aftercare. It should not promise results, name prescription-only medicines to the public, trivialise procedures, push deadlines or target minors. Use this as a working map, and have a lawyer in your country check the ad before it runs.
An ad goes to review on a Thursday: "Smooth, youthful skin in 15 minutes. Painless. Botox from a low price, this week only!" Every phrase in it is a reason for rejection somewhere. The clinic owner wrote it in a hurry, because that is how the salon down the street advertises.
This article works from the claims an ad reviewer, a platform or a regulator flags, and shows a rewrite for each. It is a map, not legal advice: the rules here are US, UK and Hungarian reference points, and you need a legal check in your own country before publishing. It is part of our aesthetic clinic marketing guide.
What can an aesthetic clinic promise in an ad?
It can promise a consultation, a qualified doctor, a clear explanation and careful aftercare, because these are things the clinic controls and can show. It cannot promise a medical result for an individual, since results vary and claims need evidence. The safest ad describes the process and invites the patient to the initial consultation.
The reason is legal status. In Hungary, section 3 e) of the Health Care Act lists aesthetic plastic invasive and minimally invasive procedures among health services, which are provided under an operating licence or, in cases the law defines, after registration (Nemzeti Jogszabálytár). An ad for those procedures is an ad for a health service, and it is judged that way.
What a clinic controls, and can therefore say:
- Who performs the treatment, and their qualification.
- What happens at the consultation and on the day.
- What the typical side effects are, and who the treatment does not suit.
- What aftercare the clinic provides, and how to reach it.
- The price of the consultation, or a price range.
Which claims do ad reviewers flag first?
Result promises, pain and downtime claims, deadlines, prescription-only product names and atypical testimonials come up first. They are flagged because each one either implies a result the clinic cannot support or pressures a medical decision. Each has a straightforward rewrite that keeps the ad useful while removing the problem.
| Flagged claim | Why it is flagged | Rewrite |
|---|---|---|
| "Look 10 years younger" | Result promise without evidence | "What a consultation for lines and wrinkles involves" |
| "Painless", "no downtime" | Trivialises a procedure; needs proof | "What most patients feel, and the typical recovery" |
| "This week only", "last 3 slots" | Pressure on a medical decision | "Book a consultation when it suits you" |
| "Botox from a low price" | Names a prescription-only medicine | "Anti-wrinkle consultation with our doctor" |
| "Zero infections, ever" | Unsupported safety claim | "How we prepare the treatment room" |
| A five-star quote: "I look 20 again!" | Atypical result as a testimonial | A quote about the explanation or the care |
The deadline and the safety claim are not hypothetical. In a 2025 ruling, the UK's ASA found that a cosmetic treatment provider's paid Instagram ad with a "Black Friday deals… won't last long" deadline and "0% infection rate" claims breached the social-responsibility rule (ASA ruling).
Can a clinic advertise botulinum toxin or other prescription-only medicines?
In the UK and Hungary, not to the public: prescription-only medicines may not be advertised. A clinic can still promote a consultation for the concern, such as lines and wrinkles, and in the UK can list the product on a website price list without claims. Check whether the specific product is prescription-only in your country.
The UK's ASA says Botox is a prescription-only medicine and cannot be advertised to the public under CAP rule 12.12, and that any Botox reference on social media, hashtags included, is likely to be an ad. It also says a clinic may promote "a consultation for the treatment of lines and wrinkles" and may list Botox on a website price list without product claims (ASA).
Hungary's medicines act bans advertising prescription-only medicines (Gyftv. section 17 (4)), and even an advert for an over-the-counter medicine may not contain a health professional's recommendation (section 17 (2) g) (Nemzeti Jogszabálytár). Whether a particular toxin product is prescription-only is set in its marketing authorisation; confirm it there rather than relying on general knowledge.
How are before-and-after images and testimonials judged?
As claims about results, so they need the same evidence as a written promise. Images or testimonials that show atypical results are likely to mislead, and a small "results may vary" line does not fix that. Use typical results with consent, or leave before-and-after images out of ads altogether and keep them for the consultation.
The US FTC's health products guidance says testimonials showing atypical results are likely deceptive and that "results not typical" does not cure it; before-and-after images can convey a claim of dramatic improvement and need substantiation like an express claim (FTC).
Hungary has a direct precedent. In 2016 the competition authority GVH fined two companies more than 20 million forints in total over unproven claims for a skin-tightening procedure; the before-and-after photos did not reflect real situations, and the authority stressed that the evidence must exist before the ad is published (Adózóna).
What do Google's health ad policies restrict?
Google restricts targeting and content. Health is a sensitive interest category, so Customer Match and remarketing segments cannot be used. Speculative or experimental treatments may not be promoted, and prescription-drug terms are restricted depending on the country. Plan ads that work for people who have never visited your site.
Two policies set this. The personalized advertising policy lists health as a sensitive interest category, which rules out Customer Match and remarketing ("your data") segments (Google Ads Help). The healthcare and medicines policy bars promotion of speculative or experimental medical treatments and restricts prescription-drug terms by location (Google Ads Help).
In practice: a search ad for "lip filler consultation" that links to a clear treatment page, with no product names, no remarketing list and no claims you cannot support, is the version most likely to pass review.
Who must aesthetic ads never target?
Minors, first of all. UK rules forbid targeting under-18s with cosmetic intervention ads, England makes it an offence to give botulinum toxin or filler injections to under-18s, and US filler approvals start at age 22. Set the age limit in every campaign and keep youth trends out of the creative.
UK guidance says ads for cosmetic interventions must not target under-18s (CAP rule 12.25) or trivialise procedures (ASA). Since 1 October 2021 it has been an offence in England to give botulinum toxin or a cosmetic filler injection to anyone under 18 (legislation.gov.uk). The US FDA says dermal fillers are approved for adults 22 and older, warns that injection into a blood vessel can cause tissue death, blindness or stroke, and tells patients not to buy fillers online (FDA).
How do you check an ad before it goes out?
Run every ad through the same short checklist, have a doctor approve the medical lines, and have a lawyer check new ad formats or campaigns in your country. Keep a record of who approved what and when. Three questions do much of the work: does the ad promise a result, name a product or push a deadline?
The checklist:
- Does it promise a result? If so, remove it or hold the evidence on file.
- Does it name a prescription-only medicine in text, hashtag or image?
- Does it say "painless", "no downtime" or anything that trivialises the procedure?
- Is there a deadline, a countdown or an expiring price?
- Is the age targeting set to adults, and is the creative free of youth trends?
- Has a doctor approved the medical lines, with a date?
- Has a lawyer checked this ad format for your country?
Example (illustrative, not a real case): the Thursday ad from the opening, rewritten. Before: "Smooth, youthful skin in 15 minutes. Painless. Botox from a low price, this week only!" After: "Lines and wrinkles? Book a 30-minute consultation with Dr Novak, aesthetic doctor. She explains what the treatment involves, the typical side effects and whether it suits you. Consultation fee shown on our price list." Six of the seven checks now pass; the seventh, the legal check, is booked for Monday.
For social posts, the social media strategy applies the same rules to an Instagram calendar. If an agency writes your ads, the agency or in-house article lists the approval questions to ask first. The full picture is in the pillar guide.

FAQ
What can an aesthetic clinic promise in an ad?
What it controls and can show: a consultation with a named, qualified doctor, a clear explanation of the treatment and its typical side effects, who the treatment does not suit, and the aftercare the clinic provides. It should not promise individual results, because results vary and claims need evidence. Have a lawyer in your country check the ad before it runs.
Can we say a treatment is painless?
Avoid it. UK guidance says ads for cosmetic interventions must not trivialise procedures, and a pain claim also needs evidence. Describe what most patients feel and the typical recovery in plain words, ideally in the doctor's own phrasing, and leave the individual answer for the consultation, where the doctor can explain what to expect.
Can we use patient testimonials in ads?
Carefully. The US FTC treats testimonials showing atypical results as likely deceptive, and a results-not-typical note does not fix that. Testimonials about the explanation, the care or the aftercare are safer than ones about how someone looks. Get written consent, keep it on file, and never edit a testimonial's meaning.
Do these rules apply in every country?
No. This article uses US, UK and Hungarian rules as reference points, and each country has its own consumer, medicines and health advertising law. The broad principles, evidence for claims and no public advertising of prescription-only medicines, are common, but the details differ. Ask a lawyer who knows your market to check your ads.
