Skin necrosis after filler: progression and care

Skin necrosis is the complication every facial harmonization professional hopes never to see, and should be prepared to recognize. It is usually the consequence of vascular compromise, and what is done in the first hours weighs more than any later management. But there is a second part of the story, less discussed: what happens in the following days and weeks, when the lesion progresses and the patient needs follow-up.

This page covers progression and care at a review level. It does not prescribe medications, doses, or specific dressings, which depend on an in-person assessment and belong to the qualified professional and the service taking over the case. For the glossary entry, see necrosis.

How does necrosis set in?

Skin depends on a continuous blood supply. When an artery is blocked, by product embolism, compression, or vasospasm, the area it supplies becomes ischemic. If flow is not restored in time, cells die, and the skin goes from ischemia to necrosis.

The mechanisms described include:

• Embolism of the injected material (see vascular embolism).
• External compression by volume or swelling.
• Associated vasospasm.
• Direct injury to the vessel.

No site is free of risk, but there are regions where the vascular anatomy is more critical. The guides on glabellar, nasal, nasolabial fold, and lip vascular occlusion detail the particulars. The overview is in vascular danger zones of the face and in safety and complications.

What are the stages of progression?

Progression varies with the extent and the response to treatment. The table describes a typical course, not a fixed clock.

Demarcation usually takes days, and complete healing takes weeks to months, depending on the extent. It is common for the lesion to look worse than it is in the early stages, because the crust and swelling increase the impression of severity, and better than it is in others, because the tissue has not yet demarcated.

The timelines are illustrative. Each case has its own pace.

What care is usually part of follow-up?

Care is defined by the professional or service taking over the case, and varies with the extent. In broad terms, the reasoning includes:

1. Keep the lesion clean and protected, with appropriate dressings, changed at the frequency set by the person in charge.
2. Avoid forcibly removing crusts, which may protect the bed that is forming.
3. Watch for signs of infection: increasing pain, purulent discharge, heat, spreading redness, and fever. See facial cellulitis after a procedure.
4. Control pain, per medical guidance.
5. Photograph the progression at defined intervals, using a standard.
6. Advise sun protection, because of the tendency for dark patches in tissue under repair (see post-inflammatory hyperpigmentation).
7. Avoid procedures in the area until healing and reassessment.

Specific care, such as the use of medications, the need for oxygen therapy, debridement, or hospital admission, must be decided by a physician with wound competence, usually in plastic surgery or dermatology.

When to refer and how to keep the bond

Early referral is management, not abandonment. Consider asking a service with resources for support when there is:

• an extensive area or one in a prominent location (nose, periorbital region, lips);
• signs of infection;
• persistent severe pain;
• visual impairment or suspected eye involvement (an emergency, see visual complication after filler);
• doubt about tissue viability or the need for debridement.

Even with the referral, keep the bond: regular contact, records, and availability. A patient who feels abandoned tends to seek other services and lose trust. See also referring patients in facial harmonization.

Also record the report as required by the rules (see adverse event reporting (NOTIVISA)). NOTIVISA is the reporting system of ANVISA, Brazil's health regulatory agency.

How to talk with the patient

Communication in serious complications calls for calm, clarity, and empathy. Avoid minimizing and avoid promising. The patient needs to know what is happening, what will be done, and that they will not be abandoned.

Document everything in the patient record, keep the signed informed consent, and consult your professional board and professional liability insurer about obligations and coverage in serious cases.

And after healing?

When the wound closes, another phase begins: aesthetic and emotional rehabilitation. Scars may be atrophic (see atrophic scar), hypopigmented, hyperpigmented, or with irregular texture. The patient may need psychological support, and the professional should be sensitive to that.

Correction options, when they exist, should wait for maturation, usually months, and be assessed by someone experienced with scars. Avoid offering early corrections. Additional procedures in the area only after careful reassessment.

Does Harmy have a role in this context?

Not in managing the complication. Harmy simulates volume and does not assess health or screen for vascular risk. Its relation to the topic is prevention: the app helps plan volume in marked areas before injection, without replacing anatomical knowledge.

For the app workflow, see how to use Harmy.

Review quiz

Skin necrosis is, in large part, the consequence of a lost minute. But once it has set in, what defines the outcome is follow-up: a present professional, rigorous records, a support team, and a patient who feels cared for to the end.
