Published on: January 14, 2026
Dissolving Lip Filler Swelling

Lip fillers seem to boost one’s beauty instantly. But like any cosmetic procedure, sometimes things do go wrong. There is a growing population of individuals dealing with aesthetic concerns, filler migration, or simply wishing to remove the lip fillers, seeking processes for lip filler dissolution.

One of the most common concerns during this process is dissolving lip filler swelling, which is a normal part of recovery when managed correctly. With any procedure, there are concerns, particularly surrounding swelling after dissolving lip fillers.

If you would like to know more about the aftercare associated with dissolving lip fillers, you’ve come to the right place.

Why Would a Patient Dissolve Their Fillers?

Dissolving lip fillers comes with certain difficulties. These include:

Dissatisfaction

Regardless of overfilling or just looking too ‘done,’ some people do not like the way they look.

Filler Migration

Filler that has gone beyond the borders of the controlled area may result in boxy or contoured shapes.

Medical Issues

The formation of nodules in the fatty tissue or persistent tissue changes may cause discomfort or aesthetic concern.

Allergic and Inflammatory Reactions

Although uncommon, inflammatory responses may require partial or full dissolution.

How Does the Lip Filler Dissolving Process Work?

Lip filler dissolving is performed using an injectable enzyme called hyaluronidase.

Consultation

A qualified practitioner will assess your lips, filler type, and concerns to determine whether dissolving is appropriate.

Preparation

A topical numbing cream is usually applied to reduce discomfort during treatment.

Injection of Hyaluronidase

Hyaluronidase breaks down hyaluronic acid-based fillers, which make up the majority of lip fillers used in the UK.

Breakdown and Absorption

Your body gradually absorbs the broken-down filler over several days.

What Do You Need to Know About Dissolving Lip Filler Swelling?

You should expect swelling when a lip filler is being dissolved.

Immediate Swelling

Swelling occurs because hyaluronidase is injected directly into sensitive lip tissue, triggering a temporary inflammatory response.

Duration

In most cases, dissolving lip filler swelling settles within 24–48 hours, although mild swelling or bruising can last a few extra days.

Why It Happens

Swelling is caused by tissue irritation, enzyme activity, and minor trauma from the injection itself.

How to Manage Swelling After Dissolving Lip Fillers

To reduce dissolving lip filler swelling and support recovery, consider the following:

Apply Ice

A cold compress can help minimise swelling and discomfort during the first 24–48 hours.

Stay Hydrated

Drinking water supports the body’s natural healing and absorption process.

Avoid Heat and Strenuous Activity

Avoid saunas, steam rooms, hot showers, and vigorous exercise for at least 48 hours.

Sleep With Your Head Elevated

Keeping your head slightly raised can help prevent fluid build-up around the lips.

Take Medication Only If Advised

Only take anti-inflammatory medication if recommended by your practitioner.

Expected Outcomes and Recovery Timeline

Initial Changes

Most patients notice visible changes within 24–72 hours as the filler begins to break down.

Final Results

Swelling typically resolves within 5–7 days, allowing the lips to settle back to their natural shape.

Is It Safe to Dissolve Lip Fillers?

Dissolving lip fillers is generally safe when carried out by a trained medical professional.

Spot Testing

A patch or test dose of hyaluronidase may be performed to check for allergic reactions.

Waiting Period Before Re-Filling

UK practitioners often recommend waiting several weeks before re-injecting fillers to allow tissues to fully recover.

Uneven Outcomes

Symmetry cannot always be guaranteed and multiple sessions may be required.

Important Considerations Before Dissolving Lip Fillers

Set Realistic Goals: Discuss achievable outcomes with your practitioner before treatment.

Understand Possible Risks: Although rare, allergic reactions or temporary textural changes may occur.

Plan for Downtime: Allow recovery time, especially before major events or photoshoots.

Choosing the Right Practitioner

When considering dissolving lip fillers, choose a practitioner who:

  • Has experience with hyaluronidase treatments
  • Provides thorough consultations and aftercare guidance
  • Practises within UK medical and regulatory standards

Choosing a qualified practitioner significantly reduces the risk of complications.
