Will It Bruise? How to Guide the Patient About Hematomas
"Will it bruise?" is one of the most predictable questions and one of the hardest to answer without falling into an extreme. Saying "no" promises what no one controls. Saying "probably yes" scares someone who has not even started. The right answer sits in the middle: the possibility exists, it has known factors, and there is something to do if it happens.
This page shows how to answer with probability in honest language, what influences bruising and how to guide the patient when it appears. The ranges are typical and clinical conduct is at the discretion of the qualified professional, according to the rules of their professional council (in Brazil, CFM, CFO and others).
What is a bruise, in simple terms?
A bruise is a small bleed under the skin that becomes visible. Technically, an ecchymosis or a hematoma, depending on size. It happens because an injection, even a well-performed one, can touch a small vessel. It is not a technique failure in itself, and it does not necessarily indicate a mistake.
It usually changes color over the days, from reddish-purple to bluish, then green and yellowish, until it disappears. Explaining those colors keeps the patient from thinking it "got worse".
How to talk about probability without making up numbers?
Do not use percentages, because you do not have reliable data on the patient in front of you and should not cite numbers without a source. Use qualitative language:
| Patient's question | Honest answer |
|---|---|
| "Will it bruise?" | "It might. It is a relatively common event." |
| "Is it very likely?" | "It varies from person to person and from area to area." |
| "Can it be avoided?" | "I can reduce risk factors, but I cannot guarantee it." |
| "In which areas is it more common?" | "In areas with thin or highly vascular skin, bruising tends to be more visible." |
The closing sentence is always the same: "I can't promise it won't happen, but I will explain what to do".
What influences the chance of bruising?
Some factors are usually considered in the assessment, without that meaning a guarantee:
- Medications and supplements that affect clotting.
- Anti-inflammatories, alcohol and habits in the preceding days.
- Individual tendency to bruise.
- Treated area, especially those with thin skin or a rich blood supply.
- Recent other procedures in the same area.
Ask about all of this in the medical history. Details on medications are in anticoagulants and injectable procedures and anti-inflammatories and bruising in orofacial harmonization (HOF). For patients who already use an anticoagulant, see patient who uses an anticoagulant.
What if a bruise appears?
Prepare the patient for what to do, before it happens:
- Don't be alarmed by the colors. The change is part of the evolution.
- Don't massage or press. It can make it worse.
- Follow what you advised about compress, rest and medication.
- Send a photo, if they want guidance. Agree on the channel.
- Recognize when it is different. Bruising that grows a lot, hurts too much, or comes with pale skin, blisters or vision changes is a warning sign.
When the patient sends a photo, ask for a standard: natural light, same distance, straight on. See patient sends an aftercare photo by WhatsApp. Comparing with the previous photo is better than a description.
When is it an emergency?
Ordinary bruising and a warning sign are different things. The signs that do not wait for the follow-up:
Handing over this list in writing is part of good practice. But the text is worthless if the patient cannot reach you. Define the channel and the response time.
How does bruising affect the patient's life?
The impact is often social. The patient worries about work, events and photos. Some points to discuss:
- schedule: avoid booking close to an event (see I have an event coming up);
- care: what they can and cannot do until it fades;
- makeup: only with the professional's clearance;
- expectation: bruising is a phase, not the final result.
That last point helps a lot: patients tend to judge the procedure by how it looks on day two, not day fifteen. Explaining that the result is not immediate has phrases for this.
Does the simulation show bruising?
No. The simulation shows a settled look, with no swelling or hematoma. Tell the patient clearly: the image does not represent the first few days.
What should be recorded?
- That the possibility of bruising was explained.
- Medications and supplements reported in the medical history.
- Guidance given and contact channel.
- If bruising occurred: date, appearance, standardized photo and conduct.
Informed consent should include hematoma as a possible event, and the patient record should track the progression if it occurs.
Frequently asked questions
Is bruising after filler normal?
It is a relatively common event that usually appears in the first hours or days and fades gradually. Bruising that grows a lot, comes with intense pain or with a change in skin color needs to be reported.
Can you guarantee there will be no bruising?
No. You cannot promise the absence of bruising, even with care. What you can do is assess risk factors and explain the possibility.
How long does a bruise take to go away?
Generally from days to a few weeks, changing color over time. The timeline varies with the area and with each person.
Can I put makeup on the bruise?
The guidance is up to the professional. In general, the patient should avoid products on the area right after the procedure and use only what has been cleared.
