Dissolve nose filler in Singapore: when it is considered, what happens and how long it takes

What does it mean to dissolve nose filler?

Dissolving nose filler means a doctor injects an enzyme (hyaluronidase) into hyaluronic acid filler in the nose, so that the filler breaks down and the body clears it over the following days. It is a medical procedure, done after a consultation and an examination, and it is used to reduce or remove filler that looks too wide, has moved, feels lumpy or is simply no longer wanted.

Most nose filler treatments go smoothly, and most people who have nose filler never need it dissolved. When dissolving is considered, the reason is usually about shape and not about an emergency.

Two points decide whether dissolving is possible at all:

• The material. The enzyme works only on hyaluronic acid filler. In a 2024 systematic review of 30 studies and 9,657 patients who had non-surgical nose reshaping, hyaluronic acid was the filler used for about 97% of patients (Song and colleagues, 2024), so most nose filler is the dissolvable kind, but not all of it.
• The cause. A nose that looks different after filler is not always showing filler. Swelling in the first days, scar tissue from earlier surgery, or a thread or implant can look similar and do not respond to the enzyme.

This page covers the decision and the process for the nose only. For how the enzyme works in every area, see the main guide to dissolving filler in Singapore. For warning signs and what can go wrong after nose filler, see nose filler complications. Both sit under filler correction at SkinRev Lab, which is offered under Dr Sin Yong, medical adviser.

When is dissolving nose filler considered?

Dissolving nose filler is considered when hyaluronic acid filler in the nose is confirmed as the cause of a shape that has settled and is still unwanted, usually a bridge that looks wide or heavy, a blunt tip, a lump, or filler that has spread sideways. It is a planned decision made after an examination, not something done on the day a concern first appears.

An examination is needed to confirm the cause. If the nose looks wider instead of straighter after repeated treatments, the usual answer is less filler, not more. See also filler migration, filler lumps and nodules and the signs of too much filler.

Is dissolving nose filler ever urgent?

Dissolving nose filler is urgent only when filler is suspected of blocking a blood vessel, and that is treated as an emergency in a hospital or by the treating doctor straight away, not as a booked appointment. Planned dissolving for shape is a different situation with a different pace.

The nose has little spare room under its skin, and its arteries connect with the blood supply of the eye, which is why warning signs here are taken seriously. Serious events are rare.

Go to an emergency department now if, after nose filler or after dissolving, you notice:

• Skin on the nose, between the eyebrows or on the nearby cheek turning pale, dusky or mottled.
• Severe or escalating pain.
• Any change in vision.
• Spreading redness with fever.

Contact the doctor who treated you as well, but do not wait for a reply before going. Do not massage, press or squeeze the nose.

Everything else on this page is about the non-urgent decision: filler that has settled and that you would like reduced or removed. Mild swelling, tenderness and a small bruise in the first days after nose filler are expected and are not reasons to dissolve. The warning signs are covered at length in the guides to nose filler complications and filler vascular occlusion.

Can all nose filler be dissolved?

Not all nose filler can be dissolved: the enzyme breaks down hyaluronic acid filler only, and it does not work on collagen stimulators, calcium-based fillers, silicone, fat, threads or implants. Knowing what was placed is therefore the first step in deciding whether dissolving nose filler is possible.

What helps to establish the material:

• Your records. The product name, the amount, the date and the area, for every treatment you can remember, including ones from years ago.
• The examination. How the nose looks and feels from the front, side and below.
• Ultrasound. A scan can show where filler sits and how deep it is, and it can sometimes suggest that a lump is not hyaluronic acid. It does not make every case simple.

Hyaluronic acid can stay in the tissue for much longer than the months often quoted, so a nose treated several times may hold more filler than expected. Old filler can usually still be dissolved, although denser or older filler more often needs a second round.

When the enzyme is not the answer. People who have had nose surgery, an implant, threads or a filler that does not dissolve need extra caution. Scar tissue and altered blood vessels change the anatomy, and some problems cannot be corrected with an enzyme. These cases are often assessed together with, or referred to, a plastic surgeon. Dr Sin Yong will say so plainly if that is the right next step. For an overview of the options by filler type, see filler correction.

What happens when nose filler is dissolved at SkinRev Lab?

At SkinRev Lab, dissolving nose filler is performed by Dr Sin Yong, medical adviser, after a consultation in which he takes a history, examines the nose, uses ultrasound where useful and agrees a plan with you. The enzyme is prescription-only and is given only after that assessment. The usual steps are:

1. History. Products, dates, amounts, earlier dissolving, nose surgery, threads or implants, medicines, allergies, and recent illness or dental work.
2. Examination. The nose is looked at from the front, the side and below, at rest and in movement, with photographs in consistent light.
3. Ultrasound where useful. A probe and gel on the skin show where the filler sits, how deep it is and where nearby vessels run. See ultrasound filler mapping.
4. Allergy check. The history comes first, including any reaction to bee or wasp stings; a small skin test may be done where appropriate.
5. The plan. Dissolving all of the filler, part of it, or none of it. No treatment is always an option.
6. The injections. After numbing cream, small amounts of the enzyme are placed into the unwanted filler through a fine needle or cannula. In the nose, small, staged doses are often used, particularly after previous surgery.
7. Aftercare and a review date. Your doctor will advise on what to avoid and when to return.

A typical filler correction session at SkinRev Lab lasts 30 to 60 minutes. Filler that was placed elsewhere can be assessed in the same way.

The planned, staged dissolving described here is separate from the urgent, higher-dose treatment that doctors use when a blocked vessel is suspected.

How long does dissolving nose filler take to work?

Dissolving nose filler usually takes a day to a few days to show its effect, because the enzyme starts breaking down hyaluronic acid filler within hours and the filler softens over the following days. The result is judged later, at a review arranged by your doctor, once swelling from the injections has settled.

1. The visit. History, examination, ultrasound where useful, and the injections.
2. First hours. The enzyme begins to break down the filler. Swelling and redness from the injections are common.
3. The first few days. The filler softens and flattens. Swelling, redness or itch usually settles within a day or two; a bruise can take longer to fade.
4. About 48 hours. A UK guideline on the enzyme suggests reassessing at about this point and repeating if needed (Murray and colleagues, 2021).
5. The review. A review of what remains, at a time your doctor sets. If filler is still present where it is not wanted, a further small session is planned.
6. After the review. New filler, if wanted at all, is considered at least two weeks after dissolving, and many doctors prefer to wait longer.

How many sessions? One session is often enough for a small, well-defined problem. Larger amounts, older or denser filler, and filler that has spread more often need two or more rounds, spaced apart. Staging lets the doctor reassess between rounds and lowers the chance of dissolving more than intended.

Timings vary from person to person, and individual results vary. Your doctor will advise on the timing that applies to you.

What does the nose look like after filler is dissolved?

After nose filler is dissolved, the nose usually returns towards the shape it had before filler, which can feel like a large change if the filler had been there for years. Dissolving removes hyaluronic acid filler; it does not reshape bone or cartilage, so the bridge height, the tip and any bump that the filler was hiding become visible again.

What people commonly notice:

• The first days. Swelling can make the nose look puffier before it looks smaller. The true result is not visible yet.
• A flatter look early on. The enzyme also breaks down some of the skin's own hyaluronic acid in the treated area. The UK guideline reports that the body restores this within about 15 to 20 hours (Murray and colleagues, 2021), so an early flatter look is often temporary.
• A lower bridge or softer tip. This is the filler volume going, and it is the expected effect.
• Remaining unevenness. Not every irregularity resolves in one round, and some filler may be left on purpose.

The enzyme acts on hyaluronic acid; a change in shape after dissolving mainly reflects filler volume being removed. Where filler had stretched the skin, the area can look a little looser for a time.

Partial dissolving is a reasonable aim. Many people want a narrower front view while keeping some height on the side profile, and a staged plan makes it possible to stop when the shape looks right to you and to Dr Sin Yong. Results cannot be promised, and your doctor will explain what is realistic for your nose.

What are the risks of dissolving nose filler?

The risks of dissolving nose filler are mainly short-lived swelling, redness, itch, tenderness and bruising at the injection sites, with allergy to the enzyme being uncommon but possible. Dissolving more or less than intended can also happen, which is one reason for small, staged doses.

• Common. Swelling, redness, itch or tenderness for a day or two, small needle marks and sometimes a bruise.
• Less common. An allergic reaction, usually local swelling that appears an hour or more after the injection and rarely something more serious. People with an untreated bee or wasp sting allergy, especially to wasps, are advised to see an allergy specialist first.
• Shape-related. More filler dissolved than planned, leaving the bridge lower than hoped; some filler left behind; or the nose simply looking as it did before filler.
• Injection-related. Any injection in the nose is given close to vessels, which is why the anatomy is assessed first and ultrasound is used where useful.

The evidence has limits. A scoping review found only five randomised trials of the enzyme, with 53 participants in total, and all of them tested small filler deposits in the skin of the arm or back, not the face (Borzabadi-Farahani and colleagues, 2024). Dissolving in the nose therefore rests on guidelines, case series and clinical experience.

Who should wait or have a different plan: people who are pregnant, people with an active infection or broken skin on the nose, and people with a known allergy to the enzyme.

After treatment, the usual advice is to avoid massage, strenuous exercise and saunas for about a day; your doctor will advise on glasses and on anything specific to you. For a fuller account, see side effects of the dissolving enzyme, filler swelling and bruising after filler.

How much does it cost to dissolve nose filler in Singapore?

At SkinRev Lab, dissolving nose filler is priced at consultation, after Dr Sin Yong has examined the nose, because the price depends on what is found. SkinRev Lab does not publish a menu price for filler dissolving.

What the price depends on:

• How much filler there is and where it sits.
• Whether ultrasound is needed to locate it.
• Whether the aim is to reduce the filler or to remove it.
• How many sessions are likely.

What to bring to the consultation:

• The product name, amount and date of each nose filler treatment, if you have them.
• Details of any nose surgery, implant or threads.
• A list of allergies, including any reaction to bee or wasp stings.
• Photographs of your nose before filler, if you have any, from the front and the side.

Questions worth asking any doctor before nose filler is dissolved:

• Is my filler the kind that the enzyme can dissolve?
• Would a scan help in my case?
• Do you plan to dissolve all of it or part of it, and in how many stages?
• What happens if I react to the enzyme?
• When is the review, and what does the price include?

It is reasonable to take time to think before agreeing to a plan. SkinRev Lab is at #B1-28 CityLink Mall, 1 Raffles Link, by City Hall MRT, and is open daily from 11am to 8pm. Consultations with Dr Sin Yong are arranged on WhatsApp at +65 8266 9585.

What are the options after nose filler has been dissolved?

After nose filler has been dissolved, the options are to leave the nose as it is, to have a small amount of filler placed again once the area has settled, or to consider a different approach such as a nose thread lift or surgery. None of these needs to be decided on the day of dissolving.

• Leave it. No further treatment is a valid choice, and some people prefer their own nose once they see it again.
• Refill, conservatively. The UK guideline advises waiting at least two weeks after the enzyme before more filler, and longer if swelling persists (Murray and colleagues, 2021). Many doctors prefer to wait longer after a larger or staged correction. Often less filler is needed than before. See filler after dissolving and nose filler at SkinRev Lab.
• A different non-surgical option. A nose thread lift uses threads instead of gel and has its own risks.
• Surgery. If the aim is a lasting change in shape, a narrower nose, or correction of a breathing problem, rhinoplasty with a plastic surgeon may suit better. See rhinoplasty versus nose filler.

If you are planning nose surgery, your surgeon will advise whether and when existing filler should be dissolved beforehand.

Whatever you choose, keep a record of what was dissolved and when. It helps any doctor who treats your nose in future.
