Who should not get facial harmonization: contraindications

Most content about facial harmonization is about who can have it. This one is about who cannot — and about the situations where the right answer is to wait.

It is worth starting with a distinction that changes everything. Contraindications fall into three categories, and confusing them is what produces both the unnecessary fear and the real risk:

• Absolute — the procedure is not done.
• Relative — they call for individual assessment, and it is often possible to proceed with adjustments.
• Temporary — the procedure is postponed, not cancelled.

Absolute contraindications to facial harmonization

There are few of them, and they are firm:

• Active infection in the treatment area. A cold sore flare, inflamed acne, folliculitis, any infectious process at the site. Injecting through infected tissue spreads it.
• Confirmed allergy to a component of the product — it is worth checking the composition on the product's registration with Anvisa, the Brazilian health regulator. A reaction to hyaluronic acid itself is rare — it is a substance the body produces — but the products contain other components, and the lidocaine present in many formulations is a known cause.
• Neuromuscular disease, in the case of botulinum toxin. Myasthenia gravis, Lambert-Eaton syndrome and amyotrophic lateral sclerosis are contraindications to toxin, which acts precisely at the neuromuscular junction that is already compromised in these conditions.
• Pregnancy and breastfeeding. There are no studies establishing safety. In the absence of evidence, an elective procedure waits.

Relative contraindications

This is where most cases live, and here the correct answer is almost never a flat "no".

Autoimmune disease

Lupus, rheumatoid arthritis, scleroderma, Hashimoto's thyroiditis and others. The group is far too heterogeneous for a single rule: what matters is the specific condition, how active it is at the moment, and the medication in use.

Controlled, stable autoimmune disease frequently does not rule out the procedure. Active disease does — and that decision is made together with the physician following the case.

Anticoagulants and antiplatelet drugs

Not a barrier, but a bruising risk factor. Medication is never stopped on the patient's own initiative, nor on the say-so of whoever is injecting — stopping it, when appropriate, is a decision for the prescribing physician.

What is done in practice is to adjust: cannula technique instead of a needle, planning with time to spare before commitments, and expectations aligned about bruising.

Tendency to keloid

Relevant for procedures that break the skin more extensively. For injectables the risk is low — the puncture is pinpoint — but it should be disclosed.

Previous filler of unknown quantity

One of the most frequent and least discussed situations. Before adding product, you need to understand what is already there, when it was done and with what. Filling over unidentified filler is like building on a foundation nobody has seen.

Diabetes, hypertension and chronic disease in general

Well controlled, they generally do not rule the procedure out. Uncontrolled, they postpone it.

When to postpone facial harmonization

• Current infection or fever, even outside the face.
• Recent or scheduled dental work. An interval of around two weeks between facial filler and invasive dental procedures is recommended, in either direction, because of the transient bacteraemia dental work causes.
• Recent vaccination. The common convention is to wait about two weeks.
• The eve of an important event. Swelling and bruising are unpredictable. The minimum safe window is two weeks, and three is better.
• Intense emotional instability, or a decision made out of comparison. It is not a clinical contraindication, and it is a legitimate reason to postpone. The procedure will still be available later.

What to avoid before the procedure

• Alcohol in the preceding 24 hours — it raises the bruising risk.
• NSAIDs, aspirin, omega-3, vitamin E and ginkgo biloba, when they are not prescribed and can be safely stopped, for around 5 to 7 days.
• Arriving after a long fast. A vasovagal reaction during the procedure is more common on an empty stomach.

And most important: disclose everything at the consultation. Medications, supplements, health conditions, previous aesthetic procedures — including the ones a person considers irrelevant or would rather not mention. Filler placed years ago by another professional is the most frequently omitted piece of information, and one of the most important.

What not to do after facial harmonization

In the first 24 to 48 hours:

• No intense physical activity
• Do not press, massage or sleep with your face resting on the area
• Avoid excessive heat — sauna, very hot showers, direct sun exposure
• No alcohol
• Do not lie down for 4 hours, in the case of botulinum toxin

In the first and second weeks:

• Avoid heat- or ultrasound-based device treatments on the treated area
• Postpone invasive dental work
• Do not assess the result before day fifteen

And the signs that call for immediate contact, without waiting for the follow-up: progressive pain, pallor or a change in skin colour in the area, altered vision, or getting worse instead of better over the days. Do not wait for the appointment.

When we advise against it, even with no clinical contraindication

Not every "no" comes from a health condition:

• Expectations incompatible with the anatomy. When the desired result requires a bone structure that face does not have.
• Someone else's face as the reference. Bringing a photo of another person as the goal produces predictable dissatisfaction.
• A request for a specific procedure with no specific complaint. Without a defined concern, there is no criterion for knowing where to stop.
• A plan sliced up by budget. When the indication only works as a whole, doing one piece unbalances instead of improving. Postponing is better.
• Rush. Someone who needs it ready by next week is asking for a risk, not a procedure.

Frequently asked questions

Can you get facial harmonization while pregnant?

The standard approach is to postpone. There are no studies establishing the safety of botulinum toxin or fillers during pregnancy and breastfeeding, and without evidence, an elective procedure waits.

Can someone with thrombophilia get facial harmonization?

It calls for individual assessment and a conversation with the physician following the case, mainly because of anticoagulant use. It is not an automatic barrier, but it is mandatory information at the consultation.

Can someone who gets cold sores have lip filler?

Outside a flare, yes — with antiviral prophylaxis, since the trauma of the needle can reactivate the virus. During an active flare, no.

I take an anticoagulant. Can I stop it beforehand?

Never on your own initiative, and never on the say-so of whoever is injecting. Only the prescriber can make that call. In most cases the procedure is done without stopping it, with an adjustment in technique.

I had filler years ago and don't know which product was used. Can I have more?

You can, but it changes the planning. Without knowing what is there, assessment is by clinical examination and, when needed, imaging. In some situations the approach is to dissolve before rebuilding.
