Thinking about dissolving your lip filler? Three questions come up more than any others: how many sessions will it take, what does it actually feel like, and how fast does it work. Here are the honest answers — including the one step most people try to rush.
What dissolving actually is
Dissolving is an injection of hyaluronidase — an enzyme that breaks down hyaluronic acid, the ingredient in most modern dermal fillers like Juvederm, Restylane, RHA, and Belotero. You may also hear brand names for the enzyme itself, like Hylenex — different labels, same job. Placed into the treated area, it breaks the filler gel down over hours to days. It's the undo button for lips that are over-filled, migrated above the lip border, or simply not what you wanted.
One important limit: hyaluronidase only works on HA filler. Permanent fillers and biostimulators like Sculptra don't respond to it — which is why confirming what's actually in your lips is the first step of any filler dissolving appointment.
How many sessions will you need?
The amount of enzyme — and the number of visits — depends on how much filler you've had injected over the years and what type of filler it was. A single conservative syringe from last year behaves very differently from several layers built up over many appointments. Some people are done in one session; many need around two to fully dissolve, and long-standing, layered filler can take more.
Dissolving doesn't have to be all-or-nothing, either. If only one spot has migrated, your injector can place the enzyme just where the correction is needed. Each visit is quick — typically 15 to 30 minutes — and dissolving at Skinsation LA is $250 per area.
- Bring your filler history — what was injected, roughly when, and where, as well as you can remember.
- Expect an exam first: your injector confirms it's HA filler and maps exactly what to dissolve.
- Plan the calendar backwards — if you want a refill, the two-week wait is part of the timeline.
What it feels like
Less dramatic than most people expect. The injection itself feels like a brief sting or a little pressure — a few small placements, usually without numbing. Afterward, swelling and some bruising are completely normal and not a sign anything went wrong. Much of it settles in the first few days, and for most people the area looks calm within a week. Any tenderness is typically mild and fades within hours to a day.
The results timeline — and the wait that matters
The enzyme works fast: 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. The enzyme stays active for roughly the first two days, and your injector may ask you to gently massage the area during that window — follow the aftercare you're given rather than a rule you read online.
Then comes the step people most want to skip: waiting at least two weeks before refilling. That pause lets the swelling resolve and the tissue settle, so you and your injector can see your true baseline and plan new lip filler correctly instead of chasing a moving target — and it helps you avoid repeating the problems, like migration, that led you to dissolve in the first place.
Dissolving is the reset, not the result — the two-week wait is part of the treatment, not a delay to negotiate.
Hyaluronidase is a medical treatment, and responses to it vary — how much filler dissolves, how quickly, and how many sessions it takes are individual. This is general education, not a treatment plan; a consultation is where we map the right approach for your lips. — Holly Adamous, MSN, RN, FNP
- Hyaluronidase (brand names include Hylenex) dissolves HA fillers only — not permanent fillers or biostimulators.
- How much you need depends on how much filler you've had, what type, and how long it's been there.
- Some people need one session; many need around two. Your injector maps it at a consult.
- It feels like a brief sting; swelling and bruising early on are normal and settle within days.
- Visible change in 24-48 hours; full dissolution up to 1-2 weeks.
- Wait at least two weeks before refilling — longer is fine.
