What Makes a Good Aesthetic Before and After Photo

Before and after photographs are one of the most powerful decision-making inputs in aesthetics, and one of the most easily manipulated. The gap between those two facts is where patients get hurt: not physically, but in terms of expectations set, money spent, and results that don’t match the image that sold them the treatment.

I want to write this article not to disparage the industry I work in, but because I think patients deserve to understand what makes a photograph a legitimate basis for expectations and what makes it a marketing tool dressed up as evidence. The standards aren’t complicated. The willingness to apply them consistently is what varies.

This guide gives you the tools to evaluate any before and after photograph, including ours.

Why Photos Are So Influential

Humans process visual information faster than text and weight it more heavily in decision-making. A before and after photograph communicates something that a thousand words can’t quite match: the suggestion that a result happened to a real person and could happen to you. When it’s genuine, that’s exactly what it is. When it isn’t, the suggestion is still there, with the same emotional weight, without the corresponding reality.

In aesthetic medicine, patients are frequently making decisions under the influence of concern about their appearance, which is a state of mind that increases susceptibility to compelling visuals. A photograph that appears to show dramatic improvement is emotionally persuasive in a way that written disclaimers rarely counteract.

Understanding this dynamic isn’t a counsel against looking at before and after photographs. It’s an argument for looking at them with appropriate scrutiny, asking the right questions, and knowing what to look for.

The Variables That Make a Comparison Legitimate

For a before and after photograph to be a genuinely comparable set of images, a number of variables need to be controlled. When any of them change between the before and after shot, the comparison is compromised, sometimes substantially.

Lighting. This is the variable most frequently manipulated, deliberately or through carelessness. The direction, intensity and quality of light changes how skin looks dramatically. A before photograph taken under unflattering overhead lighting, which creates shadows in hollows and emphasises texture, compared to an after photograph in softbox studio lighting, which fills those shadows and makes texture less visible, is not showing the result of a treatment. It’s showing the result of better lighting. The before and after should show the same lighting conditions.

Camera angle. Facial proportions change significantly with angle. A slight downward tilt of the chin in a before photograph makes the jawline look less defined and the jowl area more pronounced. A slight upward tilt in the after straightens and lengthens the face. These are small changes that produce substantial visual differences with no treatment involved. Camera distance matters too: a longer focal length compresses the face differently from a shorter one. Both sets of images should be taken at the same angle, the same distance, and with the same focal length.

Expression. A relaxed, slightly downward, expressionless face in the before and an engaged, slightly upward, smiling face in the after are showing the patient’s face in two very different muscle states. Smiling lifts the midface, tightens the jawline and makes the eyes look more open. Photographs should show the same neutral, relaxed expression in both images.

Hair and clothing. This sounds minor and is often overlooked, but a patient with their hair down and collar up in the before, and hair pinned back and neck exposed in the after, has materially changed the visual framing of the face and neck. This affects how the jawline, jowl, and neck read in the photograph.

Time of day and recent activity. Skin looks different at different times of day. Morning puffiness in the periorbital and facial area, fluid retention that varies with diet and sleep, and the flushed appearance after exercise all create variation in how the same face looks at different times. Before and after shots should ideally be taken at the same time of day and under similar physiological conditions.

Skincare and product application. A difference in moisturiser application, even without makeup, changes how the skin reflects light. Heavy moisturisation makes skin look more luminous and makes fine lines less visible. This is a subtle variable but a real one in close skin photography.

Filters and image processing. Modern smartphone cameras routinely apply skin-smoothing algorithms. Professional photography software allows for extensive manipulation of skin texture, tone and colour. Before and after photographs in aesthetics should be unaltered beyond standard exposure and white balance correction. Any skin-smoothing, blur, or texture adjustment applied in post-processing compromises the comparison.

The Questions a Photo Doesn’t Always Answer

Even when the photographic conditions are controlled, there are contextual questions that the image alone can’t answer but that significantly affect what it means.

What is the time gap between before and after? A photograph taken two weeks after lip filler shows an immediate result at peak volume. A photograph taken two years later shows durability. Both are interesting but mean different things. For treatments where results develop over months, such as bioremodelling, Fractora, or cryolipolysis, the timing of the after photograph significantly affects what’s visible. The time gap should be stated.

Is this a typical result or an exceptional one? Most clinics, quite naturally, select their best results to display. This isn’t inherently dishonest, but it should be understood as context. A representative result is what most patients will achieve. An exceptional result is what occasionally happens for a patient with ideal anatomy, ideal skin response, and ideal treatment conditions. The CAP Code requires that advertising for aesthetic treatments doesn’t present results in a way that creates unrealistic expectations. A gallery of only exceptional results with no indication of what typical outcomes look like is in tension with that standard.

Which specific treatment produced this result? Particularly in clinics offering combination programmes, it matters whether the result shown was from a single treatment or a combination of treatments, and which ones. A result produced by combining fillers, bioremodelling and skin treatment shouldn’t be attributed to a single procedure.

Is this the same patient? In the vast majority of cases, yes. But the question is worth keeping as a background check, particularly for unusual or extremely dramatic results.

What the UK Standards Require

The CAP Code, which governs non-broadcast advertising in the UK including social media, website content, and email marketing, requires that marketing communications are accurate, substantiated and not misleading. Photographs presented as before and after results are marketing communications.

Specific requirements include:

• Images must not be misleading through selective emphasis or material omission
• Results shown must be representative, or presented with appropriate context about what is typical
• Claims must be supported by evidence
• For treatments involving prescription-only medicines, advertising to the general public is restricted, and before and after photographs in advertising for these treatments are not permitted

This last point is often misunderstood. For treatments involving prescription-only medicines, before and after photographs can be shown in the context of a clinical consultation or patient information materials, but advertising them to the general public is not allowed. Clinics that freely publish before and after photographs for these treatments on public social media are operating outside the permitted advertising framework.

At LRC, we follow these standards. We don’t publish before and after photographs for prescription treatments in open advertising. Where we share results photography, it’s under the applicable conditions, and we apply the photographic standards described in this article to our own content.

Red Flags to Watch For

When you’re looking at a clinic’s before and after photographs, the following are worth noting:

• The before image is consistently unflattering in lighting, angle or expression, while the after is consistently well lit, straight-on and engaged
• Hair, clothing or positioning changes between the two images
• The before image looks like a candid or phone snapshot; the after looks like a professional studio photograph
• Skin texture in the after image is visibly smoother than would be expected from the treatment or timeframe, suggesting post-processing
• No time gaps are stated, or all after images are taken immediately after treatment regardless of how long the result takes to develop
• Only exceptional results appear, with no indication of what a typical patient experiences
• Results are shown for treatments where advertising that result is restricted

None of these is automatic proof of manipulation, and some clinics take consistently poor before photographs simply due to inconsistent process rather than intent. But a pattern of these features across a gallery is worth registering.

What Good Before and After Photography Looks Like

A photograph that represents a genuine result in honest conditions will typically:

• Use the same lighting setup, same angle, same camera-to-subject distance in both images
• Show the patient in the same neutral, relaxed expression
• Have the same hair position and equivalent clothing framing
• State clearly what treatment was performed and when the after was taken
• Be unaltered beyond standard colour correction
• Be accompanied by context about typical outcomes

At LRC, our results photography is taken under standardised clinical conditions. We use consistent positioning, the same lighting setup, and a standardised protocol for each patient. We don’t apply skin-smoothing or image filters to before and after images. We state the treatment and the time gap. We include results that represent the range of outcomes patients experience, not only the most striking.

This isn’t unusual or impressive in a well-run clinic. It’s the baseline. I mention it because not every clinic applies even this baseline, and patients should expect it as standard.

Using Before and After Photos Constructively

Photographs remain a useful part of assessing whether a treatment or clinic might be right for you, even with these caveats in mind. The questions to bring to the image are:

• Do the conditions look consistent between before and after?
• Is this result similar to what I’m hoping for, and does the treatment shown match what I’m considering?
• Is the time gap stated, and does it reflect when results from this treatment would realistically be visible?
• Does this result look like what most patients experience, or like an exceptional case?

And the conversation to have at consultation, with any clinic including ours:

• Can you show me results from patients whose starting point was similar to mine?
• What’s the typical result from this treatment, not the best possible?
• Is the result I’m hoping for realistic for my anatomy, skin type and the treatment we’re discussing?

Honest answers to those questions, more than any photograph, are what tell you whether you’ve found the right clinic.

Frequently Asked Questions

How can I tell if a before and after photo is genuine?

Look for consistency between the two images in lighting, angle, expression, and hair positioning. Check whether a time gap is stated. See whether skin texture in the after looks plausible for the treatment or whether it appears filtered. Genuine comparison photography controls these variables carefully and doesn’t require dramatic lighting changes or expression differences to demonstrate a result.

Why do before photos often look worse than the patient appears in person?

Partly because unflattering conditions, bad lighting, tired expressions, and downward angles, are chosen intentionally or carelessly for the before. Partly because our own appearance in a still photograph often reads more critically than how we look in real life and movement. A photograph that captures someone at their worst, compared to one that captures them at their best, isn’t showing a treatment result. It’s showing a range of how the same person can look under different conditions.

Can a clinic show before and after photos for any treatment?

No. For treatments involving prescription-only medicines, advertising to the general public using before and after photographs is not permitted under UK medicines advertising regulations. Clinics that publish this content on open social media or websites are not operating within the permitted framework. Before and after photographs can be shown as part of clinical consultation or patient information, but not in general advertising.

What’s a reasonable time gap for an after photo?

It depends on the treatment. Injectable treatments that work immediately, such as dermal fillers, can legitimately show a result within two to four weeks once initial swelling has settled. Treatments that work by stimulating collagen, such as bioremodelling, microneedling or Fractora, typically have their result visible at three to six months. Fat reduction with cryolipolysis is best assessed at 12 weeks. Showing a result too soon, or not stating when the after was taken, obscures how the treatment actually performs over the realistic timeline.

Should a clinic show typical results, or can they show their best cases?

The CAP Code requires that advertising doesn’t create unrealistic expectations. Showing only exceptional results without context about typical outcomes risks doing exactly that. A clinic demonstrating genuine confidence in its results should be able to show a range, not just the outliers. If every single result in a gallery is exceptional, that itself is worth questioning.

Do filters on before and after photos break advertising rules?

Yes, if they alter the appearance of the skin in a way that exaggerates the result of the treatment. Applying skin-smoothing filters to after photographs is a material alteration that the ASA considers misleading if it creates a false impression of the treatment’s effect. Standard colour correction and white balance adjustment are acceptable; texture alteration and blur are not.

What should I ask a clinic when they show me results?

Ask about the conditions under which the photographs were taken. Ask what the time gap was between before and after. Ask whether the result shown is typical or exceptional for the treatment. Ask to see results from patients who started from a similar point to yours. A clinic confident in its outcomes will be able to answer these questions. Reluctance to engage with them is informative in its own right.
