“Achieve the look you have always wanted.” Sounds harmless. Some version of that sentence sits on plenty of practice websites, usually because an agency translated it from an English template. Legally, it is a promise of results, and promising results is prohibited in advertising for medical services. Advertise like that and you are guaranteeing something no physician can guarantee, which makes you an easy target. Germany’s medical advertising law (HWG) is one of the strictest advertising statutes in the country. Many agencies have never even heard of it. And strange as it sounds, that is good news for any practice that takes its advertising seriously.
I am writing this as a practitioner, not a lawyer. My agency works with, among others, a practice group with seven locations, and every ad we build goes through the same test: does this hold up under the HWG? At first it feels like driving with the parking brake on. I see it differently now. The law filters out bad advertising before it does damage. If you master the rules, you have an edge over everyone who ignores them. The market is full of campaigns that could draw a cease-and-desist letter any day. You just have to be better than those.
The traps that actually get expensive
In my experience, five prohibitions cause most of the trouble.
First, promises of cures and results. Anything that presents a treatment outcome as certain is off limits: “permanently smooth skin,” “guaranteed pain-free.” Medicine offers no guarantees, so advertising cannot suggest any. The same goes for the softened version. A model photo with the line “This could be you” is not a workaround. It is the same promise in polite form.
Second, before-and-after photos. For a long time, many people reassured themselves that the ban only applied to surgery. In July 2025, Germany’s Federal Court of Justice made clear that it also applies to injectable wrinkle treatments. No scalpel required. If you are still running before-and-after galleries for aesthetic treatments today, you are not in a gray area. You are standing in the middle of forbidden territory.
Third, drug and brand names in consumer-facing advertising. Prescription medications may not be advertised to patients. The famous brand name for wrinkle treatment you are thinking of right now does not belong in any ad, and neither does the active ingredient behind it. We write the generic “wrinkle treatment” and lose surprisingly little. The patient still knows exactly what we mean.
Fourth, the word “free.” Free offers around medicine are tricky. An advertised free consultation quickly collides with the HWG and with the medical fee schedule. A consultation that costs something and gets credited toward a later treatment is the cleaner message. Frankly, it is also the more credible one: what costs nothing is rarely taken seriously.
Fifth, fear. Advertising that trades on health anxiety, lines like “Don’t wait until it’s too late,” is prohibited. It is also strategically stupid. Nobody wants to be treated by a practice that scared them first.
What is left is more than enough
Sounds like very little room to work with? I thought so too at first. In reality, what remains is exactly what works best anyway.
Education, for one. An ad that explains how a treatment works, which questions get answered in the consultation, how many appointments are realistic, comes across as more trustworthy than any promise. Patients research for a long time before they contact a practice. If your advertising already gives them real answers, you have built trust before the first appointment is even booked.
Then empathy. You are allowed to address the condition that brings someone to a practice, as long as you do not stoke fear and do not promise a result. The difference is tangible. “Bothered by your frown lines? In a consultation, we will calmly walk through your options” is permitted. “Never see frown lines again” is not.
And then the factors that have little to do with copy. Speed is an underrated selling point. If you can offer consultation appointments on short notice, with online booking, you can say so out loud, because it is a verifiable fact, not a promise. Same with the team’s qualifications: board certifications and memberships in professional societies are facts. And real reviews: a well-maintained Google presence with honest reviews and responses to them is more convincing than any glossy claim, and it is legally unproblematic as long as nothing is bought or filtered.
That is why “Achieve the look you have always wanted” becomes something like this with us: “What makes sense in your case is something we clarify in a personal consultation. Appointments are available on short notice, bookable online.” No promise, no superlative. And yet everything someone wants to know before making first contact is right there.
Cease-and-desist letters are almost always copy-paste
Most HWG violations I see do not come from malice. They happen because someone reused a template. From the US, where before-and-after photos are standard. From the cosmetics industry, where a “free trial treatment” bothers nobody. Or from the agency’s own portfolio, where the same copy previously advertised a gym. Then it gets translated and launched. At some point a competitor or a consumer watchdog takes notice, and the practice gets a letter from a lawyer. Not the agency. The practice.
For managing directors, the practical takeaway is this: ask your agency what the HWG means for your current campaign. If the answer is evasive, you know enough.
For everyone else, the whole thing flips. If you know exactly where the line runs, you do not have to stop three steps short of it out of uncertainty. You can build right up to it, with messaging as concrete and as confident as the law allows. That is where the impact lives, just before the line. Some can do that because they know the law. The rest are guessing, and they end up either too tame or served with a cease-and-desist.
The HWG protects patients from manipulation. That is its purpose, and it is a good one. As a side effect, it protects every practice that masters it from competitors who do not. A law as a moat. You just have to read it.
