Filler Complications 101: Red Flags, Reversals, and Aftercare
Dermal fillers can look natural and fresh when used by a trained professional. Still, every treatment has risks. This post explains the warning signs, when pros use hyaluronidase to reverse HA (hyaluronic acid) filler, and how patients can prepare for a safe, calm experience. For a deeper dive, read our Hyaluronidase article and start with our Safety Plan. Clinics can review policies on our Compliance page.
Red Flags: What’s Not Normal
Call your injector right away if you notice any of the signs below. If symptoms feel severe or you are scared, seek urgent care.
- Severe or growing pain in or near the treated area
- Pale, white, blue, or blotchy “net-like” skin; skin feels cold or numb
- Sudden vision changes, headache you cannot ignore, or dizziness
- Rapid swelling, hives, trouble breathing, or lip/tongue swelling
- Spreading redness, heat, pus, or fever in the days after treatment
- Hard, painful lumps that do not settle
These can signal problems that need fast, expert help.
When Pros Use Hyaluronidase (HA Reversal)
Hyaluronidase is an enzyme that breaks down HA fillers. Trained clinicians may use it to:
- Treat urgent issues (for example, blood-flow problems suggested by pain + skin color change).
- Fix migration or asymmetry that does not improve.
- Soften stubborn lumps or nodules after assessment.
- Clear product before a new plan.
Reversal is a professional decision. Dose, location, and timing depend on the case. Do not self-treat or “shop” for enzyme without medical guidance. Learn more in our Hyaluronidase article.

How to Prepare Patients (Calm, Clear, Safe)
- Choose a licensed, experienced injector. Ask about training, products, and emergency plans.
- Share your full health history. Include allergies, meds, supplements, and past procedures.
- Set real goals. Bring photos of the look you like; expect “fresh,” not “new face.”
- Plan your timing. Allow two weeks before big events for swelling to settle.
- Know the follow-up plan. Book a check-in. Ask who to call after hours.
- Learn the red flags. Save your injector’s number. Read our Safety Plan.
- Keep products traceable. Clinics should record brand, batch/lot, and placement (see our Compliance page).
FAQs
1) How long should I wait before judging the result?
Most swelling settles in 1–2 weeks. Review your result with your provider at two weeks unless told otherwise.
2) Do small bumps always mean something is wrong?
Not always. Soft bumps early on are common and often settle. Hard, painful, or long-lasting bumps need a professional review.
3) Can all fillers be reversed?
HA fillers can be adjusted with hyaluronidase by trained pros. Other filler types cannot be dissolved this way.
4) What if I think I have an urgent problem?
Do not wait. Contact your injector immediately. If you have severe pain, vision change, breathing trouble, or feel unsafe, seek emergency care.
