Dissolve under-eye filler in Singapore: when tear trough filler is dissolved, what happens and how long it takes

What does it mean to dissolve under-eye filler?

Dissolving under-eye filler means a doctor injects small amounts of an enzyme (hyaluronidase) into hyaluronic acid filler in the tear trough, so that the filler breaks down and the body clears it over the following days. The tear trough is the groove that runs from the inner corner of the eye across the top of the cheek, and under-eye filler and tear trough filler are two names for filler placed there.

If the concern is a lump rather than too much volume, under eye filler lumps and their causes are covered in our tear trough filler problems guide.

Most under-eye filler treatments go smoothly. Dissolving is considered when filler in this area is causing puffiness, a blue or grey tint, a lump or ridge, or a fuller look than you want, and when those changes have not settled with time.

Three things make the under-eye different from other areas when filler is dissolved:

• Thin skin. The skin here is among the thinnest on the face, so both filler and the effect of removing it show easily.
• Slow drainage. The area clears fluid slowly, so swelling can linger.
• A small space. Small amounts make a visible difference, which is why doses are small and often staged.

This page covers the decision and the process for the under-eye only. For how the enzyme works in every area, see the main guide to dissolving filler in Singapore. For the causes of puffiness, a blue tint and lumps after under-eye filler, see tear trough filler problems. Both sit under filler correction at SkinRev Lab, which is offered under Dr Sin Yong, medical adviser.

When is dissolving under-eye filler considered?

Dissolving under-eye filler is considered when hyaluronic acid filler is confirmed as the cause of puffiness, a blue or grey tint, a lump or a lasting overfilled look, and the change has continued after early swelling has settled. It is a planned decision made after an examination, and waiting or a different treatment is sometimes the better choice.

The table is a guide only; an examination is needed to confirm the cause. Puffiness and shadows under the eyes are not always filler. Allergies, sleep, salt, thyroid problems and ageing can all play a part. Related guides explain the Tyndall effect, filler swelling and filler lumps and nodules.

Is dissolving under-eye filler ever urgent?

Dissolving under-eye 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 puffiness, a tint or a lump is a different situation with a different pace.

Vessels near the inner corner of the eye connect with the eye's own circulation, which is why warning signs here are taken seriously. Serious events are rare.

Go to an emergency department now if, after under-eye filler or after dissolving, you notice:

• Any change in vision.
• Skin around the eye, nose or cheek turning pale, dusky or mottled.
• Severe or escalating pain.
• Spreading redness with fever.

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

Everything else on this page is about the non-urgent decision. Swelling in the early days after under-eye filler is expected and is not a reason to dissolve. Puffiness that is still there at about a month, or that keeps coming back, is the point at which a review is worthwhile. The warning signs are covered at length in the guides to tear trough filler problems and filler vascular occlusion.

Can all under-eye filler be dissolved?

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

Hyaluronic acid is the usual material under the eyes, but not the only one. In a systematic review of 52 published cases of delayed problems after tear trough filler, hyaluronic acid accounted for about 71% of cases, and the rest involved other materials (Trinh and colleagues, 2022). Published cases do not show how often problems happen overall.

What helps to establish the material:

• Your records. The product name, the amount and the date of every under-eye treatment, including ones from years ago.
• The examination. How the area looks at rest, when you smile and when you look up.
• Ultrasound. A scan can show where filler sits and how deep it is, can help to tell filler from held fluid, and can sometimes suggest that a lump is not hyaluronic acid.

Under-eye filler can last far longer than the six to twelve months often quoted, partly because the area moves little. Filler placed years ago may still be present and can usually still be dissolved, although older deposits more often need more than one round.

If the material is not hyaluronic acid, the plan is different and is usually more gradual. See the guide to collagen gel placed under the eyes, the signs of too much filler, and filler correction for the options by filler type.

What happens when under-eye filler is dissolved at SkinRev Lab?

At SkinRev Lab, dissolving under-eye filler is performed by Dr Sin Yong, medical adviser, after a consultation in which he takes a history, examines the under-eye, 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, eyelid surgery, medicines, allergies, and recent illness or dental work.
2. Examination. The under-eye is looked at in different light and from different angles, at rest and while smiling, with photographs. Fat bulging, skin quality and pigment are checked, because not every under-eye concern is filler.
3. Ultrasound where useful. A probe and gel on the skin show where the filler sits and how deep it is. 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, and a referral to a surgeon is suggested where that is the right next step.
6. The injections. After numbing cream, small amounts of the enzyme are placed into the filler itself, not around it.
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.

The aim under the eyes is to dissolve the unwanted filler without dissolving more than intended, since the thin skin shows a hollow readily.

How long does dissolving under-eye filler take to work?

Dissolving under-eye 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. The first few days. The filler softens. Swelling, redness or itch is common for a day or two, and a bruise is possible.
3. About 48 hours. A UK guideline on the enzyme suggests reassessing at about this point and repeating if needed (Murray and colleagues, 2021).
4. The first week or two. The area can look uneven, or briefly hollower, while the tissue settles.
5. The review. A review of what remains, at a time your doctor sets, and whether a second small session is needed.
6. After the review. A decision on whether anything should be rebuilt. Often less is needed than before, or nothing.

How many sessions? One session is often enough for a small, shallow deposit, such as a single blue-tinted patch. Larger or older deposits, and puffiness that has built up over repeated treatments, more often need two or more rounds, spaced weeks apart. Staging lets the doctor reassess between rounds and lowers the chance of dissolving more than intended.

A review of late under-eye swelling after hyaluronic acid filler describes treatment as typically involving the enzyme to remove the filler, with the dose adjusted to the individual case (Eshraghi and colleagues, 2024). Timings and results vary from person to person; your doctor will advise on what applies to you.

What does the under-eye look like after filler is dissolved?

After under-eye filler is dissolved, the area usually returns towards how it looked before filler, which means the hollow or shadow that the filler was placed to soften can become visible again. Dissolving removes the hyaluronic acid filler that is present; it does not treat the underlying hollow, an eye bag or pigment.

What people commonly notice:

• The first days. Swelling from the injections can make the area look puffier before it looks flatter.
• A briefly hollower look. The enzyme also breaks down some of the skin's own hyaluronic acid in the treated area. A UK guideline reports that the body restores this within about 15 to 20 hours (Murray and colleagues, 2021), and a hollower look early on often eases as the tissue settles.
• Less puffiness or less blue tint. Where filler was the cause, these usually ease as the filler goes. Where fluid, fat or pigment was part of the picture, some of the concern can remain.
• Unevenness. One side can respond faster than the other, and some filler may be left on purpose.

The enzyme acts on hyaluronic acid; a hollow look after dissolving mainly reflects filler volume being removed. Where filler had stretched the thin lower-lid skin, the skin can look a little looser for a time.

Partial dissolving is a reasonable aim. Some people want the puffiness or the tint gone while keeping a little support in the hollow, and a staged plan makes it possible to stop when the area looks right to you and to Dr Sin Yong. Results cannot be promised, and your doctor will explain what is realistic for you.

What are the risks of dissolving under-eye filler?

The risks of dissolving under-eye filler are mainly short-lived swelling, redness, itch, tenderness and bruising, with allergy to the enzyme being uncommon but possible. Dissolving more than intended, which can leave the hollow looking deeper, is the risk that matters most in this area and is the reason for small, precise doses.

• Common. Swelling, redness, itch or tenderness for a day or two, small needle marks and sometimes a bruise. The under-eye bruises easily.
• 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.
• Appearance-related. A hollower look than hoped, some filler left behind, a looser look where skin had been stretched, or the area simply looking as it did before filler.

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 under the eyes 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 in the area, 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. Do not press or rub the area unless your doctor advises it. For a fuller account, see side effects of the dissolving enzyme and bruising after filler.

How much does it cost to dissolve under-eye filler in Singapore?

At SkinRev Lab, dissolving under-eye filler is priced at consultation, after Dr Sin Yong has examined the area, 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, how deep it sits and whether one or both sides are involved.
• 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 under-eye treatment, if you have them.
• Details of any eyelid surgery.
• A list of allergies, including any reaction to bee or wasp stings.
• Photographs from before filler, and photographs taken in the morning and the evening if the puffiness changes through the day.

Questions worth asking any doctor before under-eye filler is dissolved:

• Is what I am seeing filler, fluid, fat or pigment?
• 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 might the hollow look like afterwards?
• 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 under-eye filler has been dissolved?

After under-eye filler has been dissolved, the options are to leave the area as it is, to have a small amount of filler placed again once it has settled, or to consider a different approach if filler was never the right tool for the concern. None of these needs to be decided on the day of dissolving.

• Leave it. No further treatment is a valid choice, and many people need nothing more.
• Refill, conservatively. A 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. People who tend to have morning puffiness, allergies or fluid retention may be more prone to swelling after filler in this area. See filler after dissolving and tear trough filler at SkinRev Lab.
• A surgeon's opinion. A bag that is firm, present all day and more obvious on looking up, or loose lower-lid skin, is usually a matter for an oculoplastic or plastic surgeon. The 2024 review notes that lower eyelid surgery may improve the appearance after the swelling has been treated (Eshraghi and colleagues, 2024). See eye bag removal in Singapore.

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