Med Spa Before and After Photos and AI

In California, a med spa's before and after photos must name the procedure performed, be comparable in lighting and pose, and state that the same results may not occur for all patients. Those words are what make a result photo honest. They are also exactly what an AI system tends to drop when it turns a gallery into a one-line description of what the practice achieves.

What the California statute says

Other states have their own rules, and many practices treat California's as the clearest model. Business and Professions Code section 651 covers healing arts advertising, and its image provisions are specific:

Models: an image of a model must say, in a prominent location and readable type, that it is a model.
Actual patients: an image that depicts the results of a procedure must specify "what procedures were performed on that patient".
Comparable views: before and after images must be comparable in presentation, "so that the results are not distorted by favorable poses, lighting, or other features of presentation".
The warning: they must carry "a statement that the same 'before' and 'after' results may not occur for all patients".
No alteration: an image that has been altered from the actual subject, or does not accurately depict the result, is prohibited.

Consent to publish a patient's photo is a separate question. We found no single federal rule written for med spa photos, so the answer lives in state law and in your counsel's advice.

The claim behind the picture

Federal advertising law reaches results claims too. The FTC's Health Products Compliance Guidance says health claims need "competent and reliable scientific evidence". That guidance is written for products; reading it onto a service is our inference, not the FTC's statement. The FTC's endorsement guides, updated in 2023, are more direct. Under 16 CFR 255.2, an ad relating a consumer's experience "will likely be interpreted as representing that the endorser's experience is representative", unless the advertiser clearly discloses the generally expected performance. A gallery of your best twelve results, uncaptioned, is making a claim about all of them.

What an AI keeps and what it loses

An assistant describing your practice works mostly from text. Faced with a gallery page, it reads the heading, the captions, the alt text and the paragraph beneath. If the only text is "Real results! Swipe to see the transformation", the description it produces is some version of "known for dramatic results". The procedure, the number of sessions, and the warning that results vary never reach the answer, because they were never there as text, or were baked into the image itself.

That is how a lawful gallery becomes an unqualified claim in someone else's words. You cannot control the summary. You can control what it has to summarize, which is the practical meaning of our semantic clarity pillar.

A caption that carries its context

An illustrative caption, not taken from a real practice:

Actual patient, cheek filler

Hyaluronic acid filler to both cheeks, one treatment session, photographed before treatment and at four weeks under the same lighting. Results vary, and the same results may not occur for all patients. Published with the patient's written consent.

Every element of that caption is plain text. The product is named in the way Botox or neurotoxin recommends, and any FDA wording follows FDA-cleared or FDA-approved.

What to do

Open your gallery and read only the text, as a machine would. For each image, add a caption naming the procedure and product, the time between photos, and the results statement. Put the disclaimer in the caption, not only in a footer. Label every model image as a model, remove any retouched photo, and move any disclaimer that exists only inside an image file into real text. Then check the same photos on Instagram and Google, where they usually travel without a word. The rest is on the med spa guide.

Not medical or legal advice. This is how AI systems read a med spa in public; the rules that bind your practice come from your state board and your own counsel.

Questions

What does California require on med spa before and after photos?

California Business and Professions Code section 651 says an image of an actual patient showing results must state, in a prominent location, what procedures were performed. Before and after views must be comparable in presentation, so poses and lighting do not distort results, and must carry a statement that the same results may not occur for all patients. A model's photo must be labeled as a model, and altered images are prohibited.

Can AI read a med spa's before and after photos?

An AI assistant reading a med spa's website works mainly from text, so what it can say about a before and after gallery comes from the captions, headings and alt text around the images. If the procedure, product and results disclaimer are only inside the image or missing, the assistant may describe the result without them. Writing that context as text next to each photo is what lets it travel with the result.
