Doctor explaining dissolving and re-filling to a client at a bright Koh Samui clinic

Sometimes the most natural new result starts with a clean slate — by removing what came before.

Can old filler be dissolved before new filler? Yes — if the old filler is hyaluronic acid, it can be dissolved with an enzyme (hyaluronidase) before new filler is placed, then you wait about two weeks for the area to settle so your injector can rebuild a fresh, natural result on a clean base.

Quick answer: Yes — old hyaluronic acid filler can be dissolved with hyaluronidase before new filler. You then wait about two weeks for the area to settle before re-filling, giving a clean base for a natural result. Only HA fillers dissolve this way. Results vary.

When dissolving before re-filling makes sense

A fresh start

If old filler has migrated, built up unevenly, or the shape is no longer what you want, dissolving first lets your injector rebuild on a clean base.

  • Old filler that has migrated out of place
  • An uneven or lumpy build-up over time
  • A shape you no longer like
  • Wanting a different style or product
  • Preparing for a fresh, natural rebuild

Better than layering

Adding new filler on top of an old, uneven result can compound the problem — sometimes resetting first gives the most natural outcome.

How dissolving works

Hyaluronidase

The Cleveland Clinic explains that hyaluronidase, an enzyme, breaks down hyaluronic acid filler, with full results in about two weeks.

Only HA dissolves

This only works on hyaluronic acid fillers. Biostimulators and permanent fillers cannot be dissolved this way, which is one reason HA is popular.

How long to wait before new filler

About two weeks

Most clinicians advise waiting roughly two weeks after dissolving before placing new filler, so any swelling settles and the enzyme has finished working.

Assessing the base

At that point, your injector can see your natural shape and plan a fresh, balanced result.

The dissolve-and-refill process

Step Timing
Consultation and assessment Day 0
Dissolve old filler Day 0 (quick)
Area settles ~2 weeks
Assess natural base ~2 weeks
Place new filler After settling

A guide only; your plan is individual.

Is dissolving safe?

Generally well tolerated

Dissolving is a common, established treatment. A patch test may be done to check for sensitivity to the enzyme.

Temporary flatness

The area may look flat or slightly wrinkled for a day or two after dissolving, before it settles — this is normal.

Why an experienced injector matters

Precision

Dissolving can be done for a whole area or just a small lump, so precise technique matters to keep the natural filler and tissue intact.

Planning the rebuild

An experienced injector plans both the dissolve and the fresh result together, for a natural outcome.

Preparing for dissolving and re-filling

To reset and rebuild smoothly:

  1. Have a consultation so Dr. Narathai can assess the old filler and your goals.
  2. Discuss whether to dissolve fully or just part of the area.
  3. Avoid alcohol and blood-thinning supplements for 24–48 hours before, where appropriate.
  4. Allow about two weeks after dissolving before new filler.
  5. Attend the reassessment so your natural base can be planned.
  6. Follow aftercare at each stage.

Frequently asked questions

Can old filler be dissolved before new filler?

Yes, if it is hyaluronic acid. It is dissolved with hyaluronidase, and you then wait about two weeks for the area to settle before new filler is placed on a clean base.

How long after dissolving can I get new filler?

Usually about two weeks, so any swelling settles and the enzyme has finished working. Your injector then assesses your natural shape before re-filling.

Does dissolving remove all my filler?

It can dissolve a whole area or just a small lump, depending on what is needed. An experienced injector uses precise technique to remove only what is intended.

Is it better to dissolve than to add more filler?

Often, if the old result is uneven or migrated. Layering new filler on an old, uneven base can compound problems, so resetting first can give a more natural result.

Can biostimulators or permanent filler be dissolved?

No. Only hyaluronic acid filler dissolves with hyaluronidase. Biostimulators such as Sculptra and permanent fillers cannot, which is one reason HA is often preferred.

Is dissolving filler safe?

It is a common, established treatment and generally well tolerated. A patch test may check for enzyme sensitivity, and the area may look flat briefly before settling.

Safety and consultation

Dissolving filler is a medical procedure and, like any injectable, carries some risk — common temporary effects can include redness, swelling, bruising or a mild headache, and less common reactions are possible. Results vary from person to person, and no specific outcome can be promised. This article is general information, not medical advice.

At LIV Clinic, every treatment begins with an in-person assessment by Dr. Narathai Vichienkalayarut, M.D., who reviews your skin, medical history and goals before recommending a personalized plan. Book a consultation to find out whether this treatment suits you.
