Before-and-after photos: what UK clinics can and cannot show

Before-and-after imagery is the most persuasive format in aesthetic marketing. It is also one of the most routinely misused. The rules are not ambiguous — but their practical implications are frequently misunderstood, and the gap between what clinics show and what the CAP Code and ASA permit is wider than most practitioners realise.

What the CAP Code says

The UK Code of Non-broadcast Advertising (CAP Code) does not prohibit before-and-after imagery for aesthetic procedures. What it prohibits is imagery that creates a misleading impression. This is a meaningful distinction. A genuinely representative before-and-after image, used with appropriate context, can comply. An image that has been manipulated, selectively photographed, or presented in a way that implies typical results — when those results are atypical — does not.

Rule 12.23 of the CAP Code prohibits marketing communications that use imagery in a way that could mislead about the likely results of a beauty or cosmetic treatment. The ASA has interpreted this consistently across its adjudications: the relevant question is not whether the result shown is genuine, but whether a consumer viewing the image would form an accurate impression of what they could typically expect from the treatment.

What "misleading" means in this context

The ASA has upheld complaints against clinics on the basis of before-and-after imagery in circumstances that did not involve any retouching or manipulation. The violation was in the photography itself: different lighting conditions between the before and after images; different angles; makeup removed in the before image and applied in the after; different camera proximity; different colour grading in post-processing.

Each of these factors can make a result appear more dramatic than it was. In combination, they can transform a modest, typical result into something that looks exceptional. That is the definition of a misleading impression — not in the sense of being fabricated, but in the sense that it does not reflect what a consumer would reasonably expect to happen to them.

Timing is also relevant. An "after" image taken at peak results — immediately after filler treatment, when swelling has resolved but before natural absorption begins — and presented as a durable outcome, can mislead about the longevity of results. The image should reflect a realistic and representative outcome at a timeframe that is typical for the patient population.

Surgical versus non-surgical results

The distinction between surgical and non-surgical procedures is relevant to how results can be presented. Surgical results — rhinoplasty, blepharoplasty, augmentation — tend to be more durable and more predictable across patients, though the range of outcomes still varies by anatomy, surgeon, and technique. Non-surgical results — dermal fillers, anti-wrinkle injections, skin treatments — are more variable, more time-limited, and more dependent on pre-treatment anatomy and individual metabolism.

This means that before-and-after imagery for non-surgical treatments carries a higher risk of creating a misleading impression of typicality, because the variation in outcomes across patients is greater. A result that was exceptional for one patient is less likely to be typical for the patient population. The ASA adjudications in this area reflect this — complaints about non-surgical treatment imagery are more frequently upheld than those about surgical imagery, partly because the gap between the result shown and what a typical patient experiences is wider.

Social media: Instagram, TikTok, and what is different

The CAP Code applies to all non-broadcast advertising, which includes social media posts that function as marketing communications. This means that before-and-after posts on Instagram or TikTok are subject to the same rules as images on a clinic website.

In practice, social media posts are often treated as though they exist in a different regulatory space. They do not. An Instagram reel showing a patient's rhinoplasty result, posted on a clinic's account or shared from a patient's account with the clinic tagged as the provider, functions as a marketing communication. The fact that it is presented in a social media format does not change the applicable regulatory standards.

TikTok has additional platform-specific restrictions on content related to cosmetic procedures, including before-and-after imagery and body-image-related content. These restrictions can be more conservative than CAP Code requirements in some areas. The most restrictive standard applies — which on TikTok may mean that content compliant with the CAP Code is nonetheless prohibited under platform policy.

Platform policies versus ASA: where they conflict

Meta's advertising policies prohibit before-and-after imagery in paid advertisements on Facebook and Instagram. This is a categorical prohibition within the paid advertising context — not a question of whether the imagery is representative or compliant with the CAP Code. An image that would pass an ASA assessment can still be rejected by Meta's automated review systems if it includes a before-and-after format.

This creates a situation where a clinic has two separate compliance obligations that need separate management. For organic social content, the relevant standard is the CAP Code as enforced by the ASA. For paid advertising on Meta, the relevant standard is Meta's platform policy, which is stricter in this specific area. Having a governance system that applies the correct standard to the correct channel — and does so consistently — is the only way to manage both obligations simultaneously.

What a compliant before-and-after image looks like

The following conditions are not a guarantee of compliance — the ASA assesses each case on its own facts — but they represent the standard that compliant imagery consistently meets:

• Identical or near-identical photography conditions: lighting source and intensity, angle, distance from subject, background
• No makeup in either image, or identical makeup in both
• No post-processing that affects skin tone, colour rendering, or contrast differently between before and after
• After image taken at a timeframe representative of typical durable results, not at peak effect
• Context provided indicating this is one patient's result and not a guaranteed or typical outcome
• Patient consent obtained and documented, including consent for the specific use (paid vs organic, website vs social)
• A record exists documenting the approval basis for the image — who approved it, against which standards, and when

Common violations and how to avoid them

The violations that appear most frequently in ASA adjudications involving before-and-after imagery are: different lighting conditions presenting the after image more favourably; "after" images taken at a non-representative point in the recovery or results timeline; images showing dramatic results without any indication of their typicality; and social media UGC (user-generated content) reshared by the clinic without any governance review of whether the image meets the applicable standards.

The UGC case is worth particular attention. A patient posting their own results on their personal account is not subject to the same rules as a clinic posting marketing content. But if a clinic reposts that content, or tags itself on it, or shares it to its own channels, it becomes a marketing communication for which the clinic is responsible. The fact that the clinic did not take the photograph does not absolve it of responsibility for the impression the photograph creates when used as marketing.

The governance principle

Every before-and-after image used in marketing should have a documented record of why it was approved: the photography conditions, the timeframe of the after image, the comparison made against the CAP Code standards, and the decision that it represents a compliant and representative result. That record does not prevent the ASA from investigating a complaint — but it demonstrates that the decision to use the image was made thoughtfully and against the right standards, rather than casually or without any compliance consideration.

In the event of an ASA complaint, the existence of a governance record is evidence that the clinic takes its compliance obligations seriously. Its absence is the opposite.
