7.8 - Advertising Rules for Beauty and Aesthetics

Every Instagram post, every TikTok, every leaflet, every website page, every message in a Facebook group - if it promotes your business, it's advertising. And advertising in the UK is regulated. The ASA (Advertising Standards Authority) and the CAP Code set the rules, and they apply to beauty professionals just as much as they apply to multinational brands. This guide covers what you can and can't say, how to use before and after photos, what happens when you mention Botox, and how to stay on the right side of the rules when promoting your services on social media.

Quick rule of thumb: if you wouldn't be comfortable defending the claim in front of an ASA panel with evidence, don't make it. "Reduces the appearance of fine lines" is usually fine. "Removes wrinkles" is almost certainly not.

The ASA and CAP Code: who enforces what

The ASA (Advertising Standards Authority)

The ASA is the UK's independent advertising regulator. It handles complaints about advertising across all media - print, online, social media, TV, radio, outdoor.

The ASA doesn't fine you directly (in most cases). But it can:

• Require you to withdraw or amend your advertising
• Publish a ruling against you (publicly, on their website - your name, your business, the complaint, and their decision)
• Refer persistent offenders to Trading Standards (who can prosecute)
• Refer online advertising to the CAP Compliance team, who can have non-compliant paid ads removed by platforms

The CAP Code (Committee of Advertising Practice)

The CAP Code is the rulebook. It covers non-broadcast advertising - which includes websites, social media, leaflets, emails, and anything else that isn't TV or radio. The BCAP Code covers broadcast (TV and radio).

For beauty and aesthetics, the CAP Code's key principles are:

1. Advertising must be legal, decent, honest and truthful
2. Claims must be substantiated - you must hold evidence before you make a claim
3. Advertising must not mislead - by action, omission, or implication
4. Advertising must not cause harm - physically or financially

Claims: what you can and can't say

This is where most beauty professionals get caught. The line between a cosmetic claim and a medicinal claim matters enormously.

Cosmetic claims vs medicinal claims

The key distinction

• Cosmetic claims describe the appearance or feel of the skin/hair: "looks smoother," "appears brighter," "reduces the appearance of"
• Medicinal claims describe a physiological change or treatment of a condition: "removes," "cures," "treats," "heals," "prevents"

If your claim crosses into medicinal territory, it falls under the Human Medicines Regulations 2012, and you need a marketing authorisation (product licence) to make it. You almost certainly don't have one. Stick to cosmetic language.

The word "anti-ageing"

"Anti-ageing" is widely used but technically problematic. Nothing stops ageing. The ASA has allowed "anti-ageing" in some contexts as a commonly understood marketing term, but:

• Don't combine it with specific efficacy claims you can't back up
• "Anti-ageing facial" is generally acceptable as a description
• "This treatment reverses ageing" is a medicinal claim and is not acceptable

"Best," "number one," "leading"

• "Best hairdresser in Manchester" - you need evidence. A verified award, a survey, something objective
• "Number one lash tech in the UK" - you need evidence. Self-proclaimed titles don't count
• "Leading aesthetics clinic" - "leading" implies market leadership. You need data
• "Award-winning" - you must name the award and be able to prove you won it. If the award expired or was from 10 years ago, that's potentially misleading

Tip for new starters: Before you post anything on social media, run it through this quick test: "Could I back this up with evidence if the ASA asked?" If the answer is no, reword it. Stick to what you can prove and describe results in terms of appearance, not cure.

Before and after photos

Before and after photos are one of the most powerful marketing tools in beauty and aesthetics. They're allowed - but with strict conditions.

The rules

1. Must be genuine - your own work on a real client. Not stock photos, not someone else's work, not AI-generated
2. Must not be digitally enhanced in a misleading way - adjusting brightness or cropping is fine. Smoothing skin, changing shape, adding filters that alter the appearance of results is not
3. Must be representative - the photos should show typical results, not your single best outcome. If 90% of clients get a moderate improvement and one got a dramatic result, showing only the dramatic result is misleading
4. Must have client consent - written consent to use the images in marketing. GDPR applies - the client can withdraw consent at any time
5. Must be taken under consistent conditions - same lighting, same angle, same distance. Different lighting can make results look more dramatic than they are
6. Must not be used for prescription-only treatments in a way that promotes those treatments to the public (see Botox section below)

Practical tips

• Take all before/after photos in the same spot in your treatment room with the same lighting
• Use a plain background
• Don't use beauty filters on Instagram/TikTok for before/after comparisons
• Save the original, unedited files - you may need to prove they're unaltered if challenged
• Keep written consent forms on file

Botox and filler advertising: the prescription-only medicine (POM) rules

This is the single biggest advertising trap in aesthetics.

Botox is a prescription-only medicine

Botulinum toxin (Botox, Azzalure, Bocouture) is a prescription-only medicine (POM). Under the Human Medicines Regulations 2012, you cannot advertise a POM to the public. Full stop.

This means:

• You cannot promote Botox by name in consumer-facing advertising (social media posts, website, leaflets, window displays)
• You cannot show before and after photos of Botox results with the intent of promoting Botox services to the public
• You cannot offer "Botox offers" or "Botox discounts" in consumer-facing marketing
• You cannot use the word "Botox" in your Instagram bio, Google Ads, or Facebook posts to promote the service

What you CAN do

• You can describe the effect: "anti-wrinkle injections," "muscle-relaxing injections," "wrinkle-smoothing treatment"
• You can say you offer the service in a clinical, informational context (e.g., a list of services on your website) - but you cannot promote or encourage people to seek it
• You can discuss botulinum toxin in an educational context - explaining what it is, how it works - without promoting it
• You can advertise a consultation: "Book a consultation to discuss your options" (without naming Botox)

Dermal fillers

Dermal fillers are not currently classified as prescription-only medicines in the UK (though the regulatory position is evolving). However:

• You still can't make medicinal claims ("fills wrinkles" - borderline; "removes wrinkles" - no)
• Before and after photos are allowed but must follow the standard rules
• "Special offer on lip fillers" is permitted but must not be misleading about price or results
• If the filler contains a medical device (many hyaluronic acid fillers are classified as medical devices), specific advertising rules may apply

The Botox trap on social media

Many aesthetic practitioners post Botox results on social media without realising they're breaking the law. The MHRA (Medicines and Healthcare products Regulatory Agency) actively monitors social media for POM advertising breaches. Penalties can include:

• Warning letters
• Requirement to remove content
• Referral to the ASA
• Prosecution (in serious cases)

Social media advertising rules

Every social media post that promotes your services is advertising. The CAP Code applies. Here's what you need to know.

Influencer and gifted content rules

If you give a free or discounted treatment in exchange for a social media post, the post must be clearly labelled:

• #ad - if you paid them or gave them a free treatment
• #gifted - if you gave them a free treatment with no obligation to post (though "#ad" is safer)
• Paid partnership - use the platform's built-in paid partnership/branded content tool where available

The label must be:

• Prominent - not buried in a list of 30 hashtags
• Upfront - in the first line or the image/video itself, not at the end
• Clear - "#ad" is clear. "#collab" is not clear enough. "#spon" is borderline

Your own posts

Your own social media posts promoting your services are advertising and must comply with the CAP Code. That means:

• All claims must be substantiated
• Before and after photos must follow the rules above
• Pricing must be clear and not misleading
• You must not make medicinal claims
• You must not promote prescription-only medicines

Testimonials and reviews

You can share client testimonials and reviews, but:

• Must be genuine - you can't make them up or pay for fake reviews
• Must be representative - cherry-picking only your best reviews while hiding negative ones can be misleading in an advertising context
• Must be verifiable - you should be able to identify the real client behind the testimonial if challenged
• Must have consent - GDPR requires consent to share someone's words in marketing
• Must not contain medicinal claims - even if the client wrote it. If a client says "my Botox was amazing," you can't share that as it promotes a POM

User-generated content

If a client tags you in a post about their treatment, that's user-generated content - not your advertising. You're not responsible for what clients post. But if you repost it, share it to your story, or use it in your marketing, it becomes your advertising and the rules apply.

Pricing and offers

Clarity

The Consumer Protection from Unfair Trading Regulations 2008 and the CAP Code both require pricing to be clear and not misleading:

• "From £30" - fine, if £30 is a real starting price that some clients actually pay
• "Was £80, now £50" - the £80 must have been a genuine price charged for a reasonable period (at least 28 consecutive days in the preceding 6 months is the general benchmark)
• "Save 50%" - the original price must be genuine and recent
• "Free consultation" - must be genuinely free with no obligation. You cannot charge if the client decides not to proceed. You cannot apply high-pressure sales tactics during a "free consultation"

Time-limited offers

"Offer ends Friday" means the offer must actually end on Friday. Rotating the same "limited time offer" indefinitely is misleading.

Package pricing

If you sell packages (e.g., "6 sessions for the price of 5"), the individual session price and the package price must both be clear. Don't hide the per-session price.

Medical device claims

Some aesthetic devices (laser machines, IPL devices, microneedling devices, LED therapy devices) are classified as medical devices under the Medical Devices Regulations 2002 (UK MDR).

If your device is a medical device:

• You must not make claims that go beyond the device's intended purpose as stated in its conformity assessment
• You must not claim the device does things it hasn't been certified to do
• Marketing for medical devices is regulated by the MHRA as well as the ASA

If your device is NOT classified as a medical device (some LED masks, some microcurrent devices):

• You still can't make medicinal claims
• Claims must be substantiated with evidence
• "FDA cleared" (if the device is cleared by the US FDA) is not automatically transferable to UK marketing - UK regulation is separate

Common advertising mistakes in beauty and aesthetics

Here are the most frequently reported issues the ASA deals with in beauty:

What happens if you get reported

1. Complaint received by ASA - anyone can complain (clients, competitors, members of the public)
2. ASA assesses - is it within their remit? Does the complaint have merit?
3. ASA contacts you - asks for your response and evidence to support your claims
4. Investigation - ASA reviews the evidence
5. Ruling - upheld (you breached the Code) or not upheld
6. If upheld - you must withdraw or amend the advertising. The ruling is published on the ASA website with your business name
7. Non-compliance - if you don't comply, the ASA refers you to Trading Standards or uses other sanctions (removal of paid ads, etc.)

Most ASA complaints in the beauty sector are resolved informally - the ASA contacts you, you change the ad, and that's it. Formal rulings are published and can damage your reputation.

Tip for new starters: Search the ASA rulings database (asa.org.uk/rulings) for "beauty" or "aesthetics" and read a few recent cases. Seeing what real businesses got pulled up for is the fastest way to understand where the lines are.

What to do next

1. Audit your website, social media, and all marketing materials against this guide
2. Remove any medicinal claims ("removes," "cures," "treats," "heals")
3. Check all before and after photos meet the rules - genuine, unfiltered, representative, consented
4. Remove any direct promotion of Botox (or other prescription-only medicines) from consumer-facing channels
5. Label any influencer or gifted content correctly (#ad, #gifted, paid partnership)
6. Review your pricing - make sure "was/now" prices and offers are genuine
7. Check that testimonials are genuine, consented, and don't contain POM references
