How a patient finds your practice. In five steps.

Lumen is made up. The method is not. This is how we build websites for aesthetic medicine.

1

She asks ChatGPT

More and more people ask an AI to recommend a practice nearby. The answer usually names only a few. To choose them, AI systems look for clear facts: specialty, location, doctor, treatments. This website provides them.

ChatGPT
Which dermatologist in Munich treats expression lines and is open about the costs?
Lumen practice, Dr Lena Example. Specialist in dermatology in Munich. Billing under GOÄ (the German fee schedule for doctors), written quote after the consultation.
Illustrative example. Nobody can guarantee a mention.

She finds clear answers

Duration, procedure, risks and costs, in calm language. No before-and-after photos and no promises of results, within the German law on advertising for medical services (HWG). She knows where she stands before the appointment.

She calls while reception is busy

In the morning the phone often rings while someone is standing at the desk. Then the AI receptionist answers. It says first that it is an AI. It answers what the practice has approved and notes a callback request. Nothing more.

AI receptionistNoted. The team will call you back on this number after 2 pm today.

She asks again at 10 pm

The practice is closed, and the AI receptionist replies: opening hours, directions, what to expect. When someone mentions symptoms, it refers them to the practice. Try it: tap a question.

Add-on: the AI receptionist is a separate module, not part of the website package. More about the AI assistants

The enquiry lands with you

Straight into the practice inbox, with the preferred date and a callback number, from chat and from the phone. Nobody asks for health data along the way. For the data processing, we sign a data processing agreement with you under Art. 28 of the GDPR (DSGVO).

This is how it arrives in the practice inbox. Sample data.

One page, two readers.

Patients see a website. AI systems only read text and data. Drag the slider: we build for both.

How it reads on the website.

No slogans. Only what patients would otherwise ask on the phone. Three treatments at the fictional practice:

Treatment of expression lines

We describe the procedure, the risks and the contraindications in detail.

Durationabout 20 minutes
Costsunder GOÄ, quote after the consultation

Hyaluronic acid treatment

We explain the risks and the alternatives. And we say no when a treatment makes no sense.

Duration30 to 45 minutes
Costsunder GOÄ, quote after the consultation

Skin texture and acne scars

First the examination, then the method. We choose the procedure together.

Why “expression lines”?Prescription-only medicines may not be advertised to patients (§ 10 HWG).
Why no before-and-after photos?They are banned, for fillers too (Federal Court of Justice, BGH, 31 July 2025).
Why so many facts?Duration, procedure and costs written as text help patients, and AI systems can quote them.
