Dissolving Lip Filler: How It Works, Recovery & Risks
Updated: 6 days ago

Quick Answer
Dissolving lip filler is a quick in-office procedure in which a licensed provider injects hyaluronidase, an enzyme that breaks down hyaluronic acid, to reverse lip fillers made from it. It treats lumps, unevenness, infection or results you dislike, takes about 10–15 minutes, and shows full results within two weeks. Anyone with a past bee-sting allergy should not receive it. [1][2]
What the research says
Most filler side effects are short-lived, and hyaluronidase is one of the tools for the ones that linger. A systematic review of 48 randomized trials on hyaluronic acid facial fillers found that most adverse events were brief injection-site reactions that settled on their own; persistent problems were treated with topical steroids, anti-inflammatory drugs or hyaluronidase. (Kyriazidis et al., Aesthetic Plastic Surgery, 2024) [3]
Delayed swelling and lumps after filler are rare. A meta-analysis of 242 studies estimated delayed inflammatory reactions at about 1 event for every 2,000 patients followed for one year, with a median onset of 3 months; treatment often involved hyaluronidase, corticosteroids and antibiotics. (Seo et al., Aesthetic Surgery Journal Open Forum, 2026) [4]
In a filler emergency, speed matters. Across 21 studies covering 231 patients with blood-vessel complications from hyaluronic acid filler, hyaluronidase resolved skin necrosis in 78.4% of cases, and treatment within 6 hours significantly improved outcomes. (Alhusain et al., Aesthetic Plastic Surgery, 2026) [5]
Key takeaways
Only fillers made of hyaluronic acid can be dissolved; silicone and other materials cannot. [1]
The enzyme hyaluronidase does the dissolving, and only a licensed healthcare provider can inject it. [1]
Treatment takes 10–15 minutes, usually needs one to two visits, and has no downtime. [1]
Expect minor swelling and bruising for up to a week; full results appear at two weeks. [1]
Wait at least 14 days before getting new lip filler. [1]
A past allergic reaction to a bee sting rules out this treatment because of the risk of anaphylaxis. [1]
What is dissolving lip filler?
Dissolving lip filler is a procedure that removes filler from your lips so they return to how they looked before the injections. [1] Lip fillers are a type of dermal filler that add volume to the lips, and dissolving them reverses that added volume. [1]
What makes lip filler dissolve?
Hyaluronidase is the enzyme providers inject to dissolve lip filler. It breaks down hyaluronic acid filler only. [1][2]
Where does lip filler go after it dissolves?
Your body naturally clears the broken-down filler material. It does not stay inside your body. [1]
Which lip fillers can be dissolved?
Lip fillers made of hyaluronic acid can be dissolved, and these are the most common type of filler. [1] Fillers that contain silicone or other substances cannot be dissolved with hyaluronidase. [1]
Filler material | Can hyaluronidase dissolve it? |
Hyaluronic acid (HA) filler | Yes |
Silicone filler | No |
Other non-HA filler materials | No |
Hyaluronidase dissolves hyaluronic acid filler wherever it was placed, including the lips, cheeks and lower eyelids. [1]
Who is a good candidate for dissolving lip filler?
A good candidate for dissolving lip filler is someone who previously had hyaluronic acid lip filler and now has a complication or dislikes the result. [1] Common reasons include:
Reason | What it looks like |
Infection | Signs of infection at or around the lips after filler |
Bumps | Lumps at the injection site |
Unevenness | Uneven lips or volume that looks unnatural |
Dissatisfaction | You don't like the size, shape or look of your lips |
Who should not have lip filler dissolved?
People who have had an allergic reaction to a bee sting should not receive hyaluronidase injections. [1] Your provider will ask about bee venom allergy first, because a past reaction raises the risk of a severe allergic reaction called anaphylaxis. [1]
How do you prepare for dissolving lip filler?
Preparing for dissolving lip filler means following your provider's instructions, which may include stopping medicines and supplements that increase bleeding. [1] Examples include aspirin and fish oil, which can also interfere with healing. [1]
If you smoke, stop several weeks before the procedure, because smoking can disrupt healing. [1]
What happens during a dissolving lip filler procedure?
A dissolving lip filler procedure is a short series of injections into the lips that takes about 10 to 15 minutes in total. [1]
Step | What happens |
1. Allergy check | Your provider asks whether you are allergic to bee venom. [1] |
2. Numbing | A numbing cream may be applied to your lips to reduce discomfort. [1] |
3. Injection | Hyaluronidase is injected into your lips with a thin needle. [1] |
4. Breakdown | The enzyme breaks down the hyaluronic acid that makes up the filler. [1] |
What happens after dissolving lip filler?
After dissolving lip filler, you may notice swelling, bruising, tenderness and other minor side effects that usually fade on their own within a few days. [1] In some cases, your provider may recommend corticosteroids or antihistamines to help with swelling. [1]
You can return to work and your usual activities right after the procedure. [1]
How long does it take for lip filler to dissolve?
Lip filler usually dissolves over one to two visits, with full results visible within two weeks. [1] You may notice some change right away. [1] Large amounts of filler or nodules can take more than one session. [1]
Time after treatment | What to expect |
Right away | Some results may already show; you can return to normal activities [1] |
First few days | Minor side effects such as swelling, tenderness and bruising usually ease [1] |
Up to 1 week | Any minor bruising and swelling settle [1] |
2 weeks | Full results; the hyaluronic acid has completely broken down [1] |
14 days or later | Earliest recommended time for new lip filler [1] |
Can you partially dissolve lip filler?
Lip filler can be partially dissolved when only one area needs correcting, such as a lump or a section you don't like. [1] Providers typically use a smaller amount of hyaluronidase for this. [1]
Does dissolving lip filler hurt?
Dissolving lip filler can cause some discomfort, as with any injection. [1] Your provider may apply a numbing cream to keep the pain mild. [1]
What are the side effects of dissolving lip filler?
The side effects of dissolving lip filler with hyaluronidase are usually mild to moderate reactions. [1] They include:
Allergic reactions
Bruising
Itchy skin (pruritus)
Pain
Rash
Skin discoloration
Swelling
Contact your provider if you notice any reaction after the procedure. [1] For more on allergic skin reactions, see our guide to hives and angioedema.
Will lips look thin after dissolving lip filler?
Lips can look thinner after dissolving lip filler because hyaluronidase also breaks down the hyaluronic acid your lips make naturally. [1] This can show up as:
Fine lines
Indentations
Sagging
The thinning may be temporary, because your body usually replaces the lost hyaluronic acid. [1] Over time, your lips return to the volume and appearance they had before filler. [1] To understand how the lips are built, see our guide to lip anatomy.
How soon can you get lip filler again after dissolving it?
You should wait at least 14 days after dissolving lip filler before getting new filler. [1] Hyaluronic acid can take up to two weeks to break down completely. [1] If you're weighing other options in the meantime, compare lip augmentation methods and the lip flip.
Can you dissolve lip filler at home?
Lip filler cannot be dissolved at home. [1] Only a licensed healthcare provider can inject hyaluronidase. [1]
When should you seek emergency care after dissolving lip filler?
Seek emergency care right away after dissolving lip filler if you have any sign of a severe allergic reaction (anaphylaxis). [1] Warning signs include:
Area | Emergency warning signs |
Breathing | Coughing, wheezing, shortness of breath |
Throat and face | Difficulty swallowing; swelling of the eyelids, lips or tongue |
Stomach | Nausea, stomach pain, diarrhea |
Learn how this reaction is treated in our guide to anaphylaxis. Filler-related problems with blood flow are a separate emergency; see vascular occlusion after dermal fillers.
