What Should Actually Be in Your Filler or Botox Consent Form

We get this question constantly from patients planning a trip to see us: how do you tell whether a clinic actually explains a procedure before you sign, versus one that just hands you a form to check a box. The honest answer is that the form itself tells you very little. What matters is the process that produces it. If the injection site and product were already decided before your skin was actually diagnosed, the consent form is just paperwork after the fact, not informed consent.

Why this question matters more now

South Korea's Ministry of Health and Welfare reported that 1.17 million foreign patients visited the country for medical care in 2024, nearly double the prior year's figure, and the highest total since the government began actively recruiting international patients in 2009. Dermatology accounted for the largest share of those visits by far: about 705,000 patients, or 56.6 percent of all foreign medical visits that year, well ahead of plastic surgery in second place. Patients from Taiwan, Japan, and mainland China drove much of that dermatology growth specifically, often on short trips built around a single procedure.

That volume changes what "informed consent" needs to mean in practice. A patient who has two or three days in Seoul, and who may be consulting through an interpreter rather than directly with the physician, has less room to catch a rushed or generic explanation than someone who can simply return for a follow-up visit next week. When the appointment window is short, whether the consultation and consent process were done properly becomes one of the only things a patient can actually verify before choosing where to go.

What a real consent conversation covers

Filler and Botox are not treatments where the outcome is visible and final the moment the needle comes out. Botox in particular has a delayed timeline: the FDA's prescribing information for onabotulinumtoxinA states that the initial effect is generally seen within a few days and reaches its peak at one to two weeks after treatment, and that each treatment's effect lasts approximately three months before it can be repeated. That means a patient cannot judge the result in the treatment room. If the dose or injection points were wrong for that patient's anatomy, it will not be obvious until days later, often after they have already left the country.

Filler outcomes depend even more heavily on individual anatomy: where the product is placed, how deep it is injected, and how much is used all shift the result and the recovery timeline. That is why we treat the diagnosis, not the product name, as the starting point. A consent form that only lists a brand name and a syringe count, without recording why that specific plan was chosen for that specific patient, is describing a transaction, not a treatment plan.

At minimum, a filler or Botox consent conversation should leave the patient able to state, in their own words: what was diagnosed and why this treatment was chosen for it, the specific product and dose planned for each area, and exactly who to contact and how if something feels wrong afterward. If a patient cannot answer those three points after the consultation, the explanation was incomplete regardless of what the form says.

How we handle this at our Gangnam location

At our Gangnam location, our chief physician, Dr. Yeonjin Kim, personally handles diagnosis and treatment planning rather than delegating the consultation and leaving only the injection itself to a physician. We keep Japanese, Chinese, and English-speaking interpreting staff on site specifically so that the consent form is reviewed with the patient in a language they actually understand, not just presented for a signature.

Treatment takes place in private treatment rooms on the second and third floors of the UH FLAT SIGNATURE Gangnam hotel building, where our clinic operates as an in-house facility rather than a separate location. Guests staying at the hotel can use the oxygen chamber and vitamin IV drip on site afterward, so recovery does not require traveling elsewhere. For a patient working with a two- or three-day window, that means diagnosis, treatment, and initial recovery can happen inside a single building without adding travel time to an already tight schedule.

What to ask before you book

If you are evaluating a clinic from abroad, ask directly whether the physician who diagnoses your skin is the same person who will perform the injection, and ask what language the consent document will actually be reviewed in before you sign it. A clinic confident in its own process will answer both questions specifically rather than in general reassurances. If the answer is vague, or if the consultation happens with one physician while a different one performs the treatment without a documented handoff, treat that as a signal to ask more questions, not fewer.

FAQ

Can I fly home immediately after a filler treatment?

This depends on the treatment area and how your body responds, so it should be discussed directly with your physician when planning your itinerary rather than assumed in advance.

Can I have a consultation without an interpreter?

At our Gangnam location, Japanese, Chinese, and English-speaking interpreting staff are on site so that diagnosis and consent content can be reviewed together with the patient.

What language will my consent form be reviewed in?

The content is reviewed with the patient in a language they understand before signing, rather than presented only in the clinic's working language.
