The aesthetic medical history: why it's long and what to disclose
The intake form before a procedure is not paperwork. What each question is looking for, what people most often leave out, and why leaving it out changes the risk.
The aesthetic medical history — the intake form you fill out before a procedure — looks like paperwork, and at plenty of clinics that is exactly what it is: a form signed quickly so the appointment can start.
Done properly, it is the single step that reduces risk most in the entire process. Each block of questions exists to answer a specific clinical question, and it is worth knowing which.
What each question on the form is looking for
Current medications
Anticoagulants and antiplatelet drugs raise the risk of bruising, and they change the technique — a preference for cannula, guidance on timing ahead of social commitments.
Immunosuppressants alter the response to infection and the way tissue heals.
Isotretinoin, used for acne, has implications for skin procedures and for healing.
Anti-inflammatories and aspirin, when taken without a prescription, can be safely paused beforehand.
And there is a rule that needs saying outright: never stop a prescribed medication on your own, or on the say-so of the person doing the injecting. Whoever prescribed it decides.
Supplements
The most commonly omitted item, because people do not think of them as medication.
Omega-3, vitamin E, ginkgo biloba, high-dose garlic and others affect clotting and increase the risk of bruising. They are not serious, and knowing about them changes the pre-procedure guidance.
Health conditions
Autoimmune disease — the specific condition, how active it is and how it is being treated all matter.
Diabetes — glycaemic control affects healing and infection risk.
Neuromuscular disease — a contraindication to botulinum toxin.
Clotting disorders — they change the plan.
Recurrent cold sores — antiviral prophylaxis is required before any lip procedure, because the trauma of the needle can reactivate the virus.
Allergies
Local anaesthetics especially, since many fillers contain lidocaine in the formulation.
Pregnancy and breastfeeding
A contraindication to elective procedures, given the absence of safety studies.
Previous procedures
This is the most important block and the most poorly answered.
What people most often leave out
Three things, with different consequences:
Previous filler. The most frequent omission and the most relevant. Someone treated three years ago often assumes it "has gone by now" — and it has not always gone. Old product in the area changes the plan, and permanent product, or product of unknown origin, changes the approach entirely.
There is also a safety issue: injecting over unidentified material raises vascular risk and makes any complication harder to manage.
Procedures done outside a clinical setting. Treatments at home, in a salon, or with product of uncertain provenance. The omission is usually out of embarrassment, and it is precisely the information that matters most.
Supplements and herbal remedies, as above.
None of this information is there to judge anyone. It is there to decide what is safe to do.
Why leaving it out genuinely changes the risk
A concrete example: someone with filler of unknown origin in the cheek comes in for treatment of the nasolabial fold. Without that information, the professional plans the injection as though the tissue were untouched.
The old material may have altered the local anatomy, displaced planes and compressed structures. Injecting blind in that scenario raises the risk of a vascular complication — and if one occurs, managing it is harder because nobody knows what is in there.
The medical history is not there to protect the professional. It is there so you don't go through that.
What a good consultation has beyond the form
- A conversation, not just a form. Follow-up questions about the answers given.
- Standardised photography. Same light, angle and distance, before any injection.
- Clinical examination, including palpation of the area to be treated — that is how you find old product the person forgot to mention.
- Assessment in profile, not only from the front.
- A discussion of expectations. What bothers you, for how long, and what you are hoping for.
- Informed consent, explained rather than merely signed.
An assessment that takes ten minutes and ends in an injection on the spot has not had time to do any of that.
When we don't go ahead
- When information is missing and cannot be clarified. Unidentified previous filler, for instance, may require investigation before any injection.
- When there is an uncontrolled condition that needs medical assessment first.
- When the person does not want to answer. That is their right, and it is a reason not to proceed.
- When the procedure was decided before the assessment. At that point the form becomes a formality, and the conversation has to start over.
Consent is not the same thing
It is worth separating two documents that tend to be signed together and serve different purposes.
The medical history collects information: it is you informing the professional about your health, so they can decide what is safe.
Informed consent runs the other way: it is the professional informing you about the procedure, the risks, the alternatives and what to expect, so that you can decide.
Signing a consent form when nobody has explained its contents empties the document of what it is supposed to be.
Frequently asked questions
Why is the medical history so long?
Because injectable procedures interact with medication, health conditions and previous treatment. Each block answers a specific clinical question.
Do I really have to disclose old procedures?
Yes, and it is the most important information there is. Previous product changes the plan, the technique and the approach if something goes wrong.
Can someone with fibromyalgia have aesthetic treatment?
Generally yes. What matters is recording the condition and the medications in use, and agreeing up front that pain sensitivity may be heightened.
Do I need to stop my medication beforehand?
Only if whoever prescribed it says so. Never on your own, and never on the say-so of the person injecting.
Is the form confidential?
Yes. Health information is protected by professional confidentiality and by data protection law.
