Put a PRP and PRF before and after side by side and you will see two photographs that do not belong in the same gallery. One shows a face that looks marginally better in a way most patients struggle to name. The other shows a change so legible that the patient does not need it explained.
Both are honest images of successful treatments. That is exactly the problem. When two products in the same category photograph this differently, the gallery starts doing your consenting for you, and it tells a story the consent form does not.
Two photographs, two mechanisms
The PRP photograph is a skin-quality photograph
Tatiana Sarmiento's own description of a facial PRP result, taught in Empire Medical Training's curriculum, is unusually candid: in the before-and-after you do not see a dramatic change. What you see is that the pores look more closed, the tone is more even, the patient looks refreshed. She also teaches that the patient should not expect to see this on the same day — that the honest window is one to two weeks at the earliest, with four weeks being when the change is typically most apparent.
That is a truthful account of what PRP does. It acts on skin behaviour over time. The result is real and it is diffuse, which means it is distributed across a whole surface rather than concentrated anywhere the eye can anchor on.
Diffuse changes photograph badly. Not because they are small, but because there is no reference point in the frame against which the improvement can be measured.
The PRF tear trough photograph is a contour photograph
The infraorbital result is the opposite case. Tatiana Sarmiento describes it as a visible change in filling and in colour, and as the kind of before-and-after in which the patient sees a dramatic difference.
The optics behind that are worth understanding because they explain why the effect is amplified in an image. Filling a hollow changes the photograph twice. It changes the contour itself, and it removes the shadow the contour was casting. An area that read as dark in the first image reads as lighter in the second without any pigment having changed at all.
So a modest, real anatomical change produces a photographic change that looks considerably larger than it is. Nothing has been faked. The camera is simply very good at recording the removal of a shadow.
These figures reflect Tatiana Sarmiento's clinical practice as taught in Empire Medical Training's hands-on curriculum. Technique is learned under supervision; this article is educational and is not a substitute for training.
Why this asymmetry corrupts consent
The mechanism is simple and it operates in every practice that shows images.
Patients do not build expectations from consent forms. They build them from pictures. A patient who has seen a striking infraorbital result on your wall, your website or your social feed has already formed a belief about what "the regenerative treatment" does, and that belief will not be dislodged by a paragraph they sign four minutes before treatment.
Three specific failures follow.
Cross-product contamination. A patient shown a dramatic PRF tear trough result and then treated with PRP on the full face has been set up to be disappointed by a successful treatment. The two products were never going to produce the same class of photograph.
Category confusion. A photograph that looks like structural correction invites the patient to hear a structural promise. Neither PRP nor PRF is a filler. Neither restores lost structural volume, repositions tissue or corrects laxity. If the clinical job is genuinely volume replacement, the honest answer is a different category of product — which is why being precise with yourself about where facial volume is actually lost and about the real difference between stimulating tissue and replacing it is a consent issue and not just a planning one.
Durability overreach. A striking image implies a durable result. Current evidence does not support that assumption in this region: a systematic review of 14 studies of platelet concentrates in periorbital rejuvenation found improvements often diminished by six months (Sollitto et al., Journal of Cosmetic Dermatology, 2025). If a patient's mental image of the outcome came from a photograph taken at the peak, they have not been told about the curve.
Standardised photography is a consent instrument
The fix is not to stop taking photographs. It is to take them in a way that makes the subtle result visible and stops the dramatic result from exaggerating itself.
A minimum standard, applied identically at every visit:
- Fixed camera distance and focal length. Changing either alters apparent facial proportion between images.
- Fixed lighting, from fixed positions. This is the single largest source of artefact in periorbital photography. Shadow depth in a hollow is a function of where the light is. Move the light and you can manufacture or erase the result without touching the patient.
- Fixed head position, including chin angle. Tilt changes apparent infraorbital shadow dramatically.
- Neutral, repeated expression. No smiling in one image and not the other.
- Same background, same camera, no filters, no post-processing, no beautification. Any device-level smoothing must be off. A smoothing filter erases the exact texture change a PRP result consists of, and flatters the skin equally in both images.
- Recorded time points, not convenience shots. For PRP, baseline and four weeks minimum. Where durability is the question, a six-month image is the honest one to have.
Two of these do specific work here. Fixed lighting stops the PRF contour result from being inflated by shadow. Standardised, unfiltered capture is the only way a PRP result becomes visible at all — the change genuinely is there, and casual photography reliably destroys it.
The practices that get into trouble with regenerative injectables are rarely the ones with poor outcomes. They are the ones whose baseline photograph was taken in whatever light was available, on a phone, with beautification on, and who then had nothing credible to compare against.

What to actually say, by product
Expectation-setting works better as three sentences said out loud than as a paragraph signed. Say what will change, say what will not change, and say when.
For a PRP skin-quality treatment: "This works on the quality and behaviour of your skin — texture, tone, how refreshed it looks — over weeks, not on the day. Most people notice it at around four weeks, and it is a subtle change rather than a dramatic one. It will not add volume, lift anything, or remove pigmentation conditions such as melasma. We will take standardised photographs, because this is the kind of change that is genuinely hard to see without them."
For a PRF treatment in a hollow: "This is likely to look like a more obvious change than a skin treatment, because filling a hollow also removes the shadow it was casting. It is not a filler and it is not permanent — the published evidence shows improvements in this area often fade by around six months, so plan for a series and for maintenance. I would rather you were pleased at six months than surprised."
Neither script promises anything, and neither needs to. Both replace a promise the gallery was making on your behalf.
Document the expectation, not only the risk
Most aesthetic consent documentation is built around risk disclosure and says little about outcome expectation. For regenerative injectables that is the wrong emphasis, because the complication rate is low and the dissatisfaction rate is driven almost entirely by mismatched expectation.
Three additions are worth making to your documentation for this category, alongside the usual risk and aftercare content that any good consent form structure already covers:
Record which product and why. "PRF selected for localised support in the infraorbital hollow; PRP discussed and not selected" is a two-line note that answers the most likely future question about the case.
Record the expected class of result and the time to see it, in the patient's terms, in your words. Not "patient consented" but "patient advised change will be in skin quality at around four weeks, not volume."
Record the maintenance conversation and when it happened. A maintenance plan discussed before the first treatment is a treatment plan. The same plan raised after the result fades sounds like an upsell, however genuine it is.
None of this constitutes a guarantee of any result, and none of it should be written as one. It is a record that the right conversation happened at the right time.
The underlying discipline
The product determines the photograph. The photograph determines the expectation. The expectation determines whether a clinically successful treatment is experienced as a success.
Which means product selection is not only a clinical decision — it is the first step of the consent conversation, and it should be discussed with the patient in those terms rather than presented as a technical choice made behind the scenes.

Frequently Asked Questions
Why does a PRP result look so much less impressive in photos?
Because the change is diffuse. PRP acts on skin texture, tone and luminosity across a whole surface, and a distributed change gives the eye no reference point in the frame to measure against. The result is real; it is the photograph that struggles. Standardised, unfiltered imaging at fixed lighting and distance is what makes it visible.
Is it misleading to show a PRF tear trough before-and-after?
Not if it is captured honestly and captioned accurately. Filling a hollow changes both contour and the shadow the hollow was casting, so a modest anatomical change reads as a larger visual one. The risk is showing it without stating the product, the number of sessions, the time point, and that improvements often fade by around six months.
How do I stop the gallery from setting expectations I have to manage?
By making product-specific expectation-setting an explicit part of the consultation rather than leaving it to images. Say what will change, what will not change, and when — out loud — and record it. A patient who has heard the right three sentences is far less influenced by a photograph of a different product.
Should maintenance be discussed before or after the first treatment?
Before, always. A maintenance plan raised in advance reads as a treatment plan; the identical plan raised once a result has faded reads as an upsell, however genuine. Given that periorbital PRF improvements often diminish by six months, the maintenance conversation is part of informed consent, not a follow-up sales step.
