Before a patient sits down with me for dermal fillers, one of the most common questions I hear is some version of this: "If I don't like it, can it be undone?" The honest answer is that it depends, and understanding exactly what that dependence looks like changes which treatment I recommend and how we plan it together. So I want to walk through what I actually tell my patients at Dr. Cris Studio about dissolving filler in NYC, including what hyaluronidase is, which fillers it works on and which it doesn't, and what the experience looks like in practice.
What Is Hyaluronidase?
Hyaluronidase is an enzyme, naturally produced in the body, that breaks down hyaluronic acid. In aesthetics, it's used as an injection to dissolve hyaluronic acid-based dermal fillers when a patient wants to reverse or correct their results. It isn't a new tool; physicians and nurse injectors have been using it for years both to correct cosmetic outcomes and, critically, to manage rare vascular complications from filler injections.
When I inject hyaluronidase into an area that has been treated with hyaluronic acid filler, the enzyme gets to work immediately, breaking the molecular bonds that give the filler its structure. Most patients begin to see visible changes within 24 to 48 hours, and the full effect typically settles over one to two weeks as the dissolved material is absorbed and the tissue softens back toward its natural state.
Which Fillers Can Be Dissolved (and Which Cannot)
This is the part that matters most, and it's something I explain carefully before any filler treatment because it affects the decision about which product to use.
Hyaluronidase works specifically on hyaluronic acid fillers. The most common ones in my practice, Juvederm, Restylane, Revanesse Versa and the RHA collection, are all hyaluronic acid-based, meaning they can all be dissolved with hyaluronidase if needed. These are the fillers I use for lips, cheeks, under-eye hollows, jawline definition, and most of the volume and softening work I do at Dr. Cris Studio.
Biostimulatory products, including Radiesse (calcium hydroxylapatite) and Sculptra (poly-L-lactic acid), cannot be dissolved with hyaluronidase because they don't contain hyaluronic acid. This is an important distinction. When I recommend one of these products, it's usually because I want the patient to experience gradual, long-lasting collagen stimulation rather than immediate filler volume, and that longevity comes with the trade-off that there is no enzymatic reversal available. Fat transfer and silicone are also not reversible with hyaluronidase.
When I present a patient with treatment options, this is part of the conversation. Some patients feel more comfortable starting with hyaluronic acid fillers precisely because of the reversibility; others are ready for the commitment that biostimulators represent. Neither is wrong.
When I Recommend Dissolving Filler
Most patients who come to me asking about filler dissolution fall into one of a few categories, and I want to be honest about each.
The first is the patient who had filler placed elsewhere and isn't happy with the outcome, whether because of asymmetry, overfilling, migration, or a look that doesn't feel like them anymore. In these cases, hyaluronidase is genuinely useful, though I do a careful assessment first: how old is the filler, what product was used, and where exactly is it sitting? Very old filler that has already partially broken down on its own can sometimes behave differently than fresh placement.
The second category is the patient who has filler I placed myself, and who returns within the first few weeks with a concern. This is less common than people assume, partly because I tend to underfill and refine rather than stack volume in one session, but when it happens I take it seriously and address it promptly. A follow-up visit and, if needed, a small amount of hyaluronidase in the precise area of concern is the right response.
The third category is the patient who comes in anxious about committing to filler at all. For these patients, I always explain: if we start with a hyaluronic acid filler and you feel it's too much at your two-week follow-up, we have a reliable way to reduce or remove it. That safety net matters, and it's one reason I often recommend starting conservative.
What the Process Looks Like at Dr. Cris Studio
A dissolution appointment is straightforward. After a thorough consultation and a review of what was used previously (ideally with records from the original injector, though not always possible), I map the area carefully. Hyaluronidase is injected in small amounts, directly into the zones where filler is present.
There's minimal downtime. Some swelling and redness in the treated area is expected for 24 to 48 hours, and I always schedule a follow-up to assess the result. Dense or layered filler from multiple treatment sessions over the years may require more than one dissolution appointment, and I'm honest about that upfront rather than promising a single-visit correction.
After dissolution, if a patient wants to replace what was removed, I typically recommend waiting at least two to four weeks before placing new filler, to give the tissue time to settle and to let me assess the baseline we're working from.
How Long Does It Take to Work?
The timeline is reassuringly fast relative to the anxiety that can surround the question. Most patients see a noticeable softening within the first 24 to 48 hours, with the complete picture clear at around two weeks. For patients who have had multiple layers of filler placed over years, the timeline varies and a second treatment session may be needed to address remaining product.
I tell patients to come in for their follow-up before making any decisions about next steps. Sometimes the two-week result is exactly what they hoped for; sometimes there's a zone that still feels dense and needs a second pass. The process is iterative, and I'd rather pace it correctly than rush.
Can You Get Filler Again After Dissolving?
Yes, and many patients do. After dissolving filler and allowing the appropriate recovery window, placing new hyaluronic acid filler is entirely safe. In some cases, patients use dissolution as an opportunity to reset and start fresh with a different approach, perhaps lighter product, a more refined placement strategy, or a shift from volumizing to contouring. I find those conversations genuinely interesting, because they give me the chance to understand what the patient actually wanted from the beginning and how we can get there together.
If you're considering dermal fillers for the first time and the reversibility question is at the front of your mind, I'd encourage you to start with a consultation. Understanding the full range of options, including the exit strategy, is part of what makes the decision feel right.

Frequently Asked Questions About Dissolving Filler in NYC
Can all dermal fillers be dissolved?
No. Only hyaluronic acid fillers, such as Juvederm, Restylane, Belotero, Revanesse Versa and RHA, can be dissolved with hyaluronidase. Biostimulatory products like Radiesse and Sculptra, as well as fat transfer and silicone, cannot be reversed with this enzyme.
How quickly does hyaluronidase work?
Most patients see visible changes within 24 to 48 hours of treatment, with the full effect settling over one to two weeks as the dissolved material is absorbed by the body.
Is dissolving filler painful?
The injections are comparable to filler placement, and I apply topical numbing before the treatment or nerve blocks. Some patients experience mild swelling and tenderness in the area for a day or two afterward.
How many sessions does it take to dissolve filler?
For mild amounts of filler, a single session is often sufficient. For patients who have had multiple treatments over time or significant volume, more than one session may be needed. I discuss this honestly during the consultation.
How soon can I get new filler after dissolving?
I generally recommend waiting two to four weeks after dissolution before placing new filler, to allow the tissue to settle and give us a clear starting point.
Can I dissolve filler I had done at another practice?
Yes. I see patients who had filler placed elsewhere and want to correct or reverse the results. Ideally, knowing which product was used is helpful, but I can assess the situation and proceed even without prior records.
Will dissolving filler leave me looking worse than before?
In most cases, dissolving brings the tissue back toward its pre-filler baseline, though there can be some temporary swelling. For patients who had filler for years, the undissolved state may look slightly different from what they remember before they ever had filler, because the filler had been there a long time. I discuss realistic expectations at the consultation.
