Not always. If your old lip filler still sits where it was placed and the shape is close to what you want, more can be added on top of it. If it has moved above the lip line, settled unevenly between the two sides, or left lumps that have not gone down, dissolving first gives your injector a clean baseline to plan from. Here is how we decide at Skinsation LA in Los Angeles, and what the dissolve, reset, refill sequence looks like from the first visit to the settled result.
Do you need to dissolve old lip filler before refilling?
Hyaluronic acid lip filler typically lasts 6 to 12 months, and because the lips move more than the cheeks or chin, filler there cycles faster than filler in less mobile areas. It does not always leave evenly. Some of it can migrate above the vermilion border, the edge of the lip; some can settle more on one side than the other; and some can stay as a small firm spot long after the rest has gone. That leftover product is what the refill decision turns on.
When the old filler is still where it was placed and the lips simply look softer than they did, there is nothing to undo, and a touch-up adds to a good base. When the old filler has moved or sits unevenly, adding more on top repeats the problem rather than correcting it, and overfilling is the most common reason lips end up looking done. That is when we dissolve first, let the lips reset, and refill once we can see your natural baseline. Our own Instagram post on the sequence puts it in three steps:
Dissolve old filler. Reset and assess. Refill.
When is dissolving first the right call?
We recommend dissolving before refilling when the lips look migrated above the lip line, when asymmetry or lumps have not resolved with time and the gentle massage your injector may have asked for, when the lips are over-filled, or when you want to start over with a different plan or a different injector. Hyaluronidase is also used urgently in the rare event of a vascular occlusion, filler injected into a blood vessel, which is why our injectors keep it on site. That is an emergency, and the right first step is to call us.
One thing is settled before anything else: hyaluronidase only breaks down hyaluronic acid filler, which covers most modern products, including Juvederm, Restylane, the RHA family, and Belotero. Fillers that are not hyaluronic acid, such as silicone or PMMA, and biostimulators such as Sculptra do not respond to it. If you are not sure what was placed in your lips, confirming that is the first part of a filler dissolving appointment. Dissolving is a medical treatment, and every injectable plan at Skinsation LA sits under the medical oversight of Dr. Lusanik Galustian, MD, our founder and medical director.
Whether to dissolve, add, or leave the lips alone is decided at an in-person exam, not from a photo or a description. Responses to hyaluronidase vary, and how much filler dissolves, how quickly, and how many sessions it takes are individual. — Dr. Lusanik Galustian, MD
When can you add filler without dissolving?
If the exam shows the old filler sitting where it was placed, with no migration, no lumps, and a shape you still like, there is no reason to clear it, and a refresh simply adds to it. We plan lip filler around your face rather than a trending look, and we never place more than one syringe in a single sitting; if more is wanted it is added 2 to 3 weeks later once the swelling has settled. Most clients refresh lip filler every 6 to 12 months depending on the product used. Your injector keeps the result balanced, because overfilling is the first reason lips stop looking like lips.
What does dissolve, reset, refill look like?
The post from our feed embedded below shows the sequence on one client, photographed in profile: the lips with the old filler, the lips after it was dissolved, and the lips after they were refilled. The middle frame is the step people most want to skip and the one that makes the refill work, because it is the first time the injector can see the lips without the old product shaping them. Individual results vary, and the point of the three frames is the order of work, not a promised outcome.
- Bring your filler history, as well as you can remember it: what was injected, roughly when, and where.
- Expect an exam first. Your injector confirms it is hyaluronic acid filler and maps exactly what to dissolve.
- Plan the calendar backwards. At least two weeks between the last dissolving session and the refill, then about 14 days for the refill to settle, with nothing important booked inside that window.
How long should you wait between dissolving and refilling?
At least two weeks, and longer is fine. Hyaluronidase works quickly: most filler is visibly reduced within 24 to 48 hours, with full dissolution taking up to one to two weeks depending on how much filler is present and how long it has been there. The enzyme is non-selective, so your injector places it only in the area being corrected, and if one spot has migrated it can be placed just there. Some people are done in one session; many need around two, and heavily layered filler can take more.
The two-week pause after the last dissolving session is part of the treatment, not a delay. It lets the swelling resolve and the tissue settle so you and your injector can see the true baseline and plan the new filler to it, instead of chasing a result that is still changing. Refilling early works against the reason you dissolved. Our post on what happens when you dissolve lip filler covers the sessions, what the injection feels like, and the results timeline in detail.
What does the refill look like after dissolving?
Once the lips have settled, the refill is planned like a first appointment, not a repeat of the last one. Your injector analyzes lip shape and proportions in a handheld mirror, asks what you want and what you want to avoid, takes reference photos, and signs off the plan before anything is placed. A half syringe (0.5 mL) gives subtle definition and balanced proportions; a full syringe (1.0 mL) is for a noticeable change in shape. We use hyaluronic acid fillers exclusively for the lips, Juvederm Volbella, Restylane Kysse, and the RHA family, so the new result is as reversible as the old one was. Lip filler at Skinsation LA is placed with a needle for definition and a cannula for the deeper layers, and you can watch in the mirror as we work.
Lips swell more than other filler areas, so plan a quiet 24 to 48 hours. Swelling peaks on days 2 to 3, when the lips can look larger than the final result, and bruising at the injection points is possible. The filler has fully settled by day 14, when the final shape and volume are visible and a touch-up can be scheduled if one is wanted. Persistent lumps or visible asymmetry beyond 14 days are specific reasons to contact us; our lip filler aftercare page lists the rest.
Our office is on San Vicente Boulevard in Carthay Circle, and we see clients for dissolving and lip filler from across Los Angeles, Beverly Hills, and West Hollywood.
- Old filler that sits where it was placed is a base to build on; filler that has migrated, settled unevenly, or left lumps is cleared first.
- Hyaluronidase only dissolves hyaluronic acid filler, and it is non-selective, so it is placed only where the correction is needed.
- Visible change in 24 to 48 hours; full dissolution in up to one to two weeks; some people need one session, many around two.
- Wait at least two weeks after the last dissolving session before refilling. Longer is fine.
- The refill is planned like a first appointment: never more than one syringe per sitting, settled by day 14.
