Under-eye filler uses very little product, so most of the cost is in assessment, technique and follow-up. At IN Eternity Clinic on Orchard Road, Dr Sin Yong decides first whether filler is right for your eyes, then quotes in writing.
WhatsApp to Enquire →Key facts ↓Under-eye filler cost in Singapore depends on the hyaluronic acid product, the small amount usually needed, the technique, any ultrasound assessment, and how review and adjustment are handled. In this high-risk area, assessment and skill matter more than volume. At IN Eternity Clinic, Dr Sin Yong gives a written quote after assessment.
Most filler pricing is built around the syringe: how many millilitres are used. Under the eyes that logic breaks down. The amounts involved are small, and putting in more is usually the mistake, not the remedy. What you are really paying for is the judgement to decide whether filler is right for you at all, the choice of product, the depth and technique of placement, and the follow-up if something needs adjusting.
That is why a low per-syringe price for the tear trough can be misleading. It may encourage using a whole syringe where a fraction is enough, or skip the assessment that tells a hollow apart from a bag. The lowest-cost under-eye treatment is often the one you never have, and the most expensive is the one that has to be dissolved and redone.

The main factors are summarised here.
| Factor | What changes | Why it affects cost |
|---|---|---|
| Product | Soft, low-water hyaluronic acid | Suitable products are specific to this area |
| Volume | Small amounts per side | Opened product is single-use and not kept |
| Assessment | Examination, ultrasound if past filler | Finds bags, old product and risk |
| Technique | Deep cannula placement | Slower, safer work in a high-risk area |
| Review | Check after swelling settles | Allows a small, measured top-up |
| Correction | Hyaluronidase if needed | A separate medicine and procedure |
Product. Under-eye skin is thin and shows swelling easily. A soft hyaluronic acid filler that draws in little water is chosen to avoid a puffy look. That product is matched to the area; a firmer, cheaper filler designed for cheeks or chin is the wrong tool here.
Volume. Small volumes per side are usually enough, and both sides may be treated from less than a full syringe. Once opened, a syringe is single-use and is not stored for a later visit, which is why a quote is often per treatment rather than per millilitre. Any product left over is discarded rather than used elsewhere, and the quote should reflect the amount planned, not a full syringe by default.
Assessment and technique. The area has a dense network of vessels, and published reviews of blindness after filler include the periorbital region among the reported injection sites. Deep placement with a fine blunt cannula, slow injection and small amounts take more time than a quick needle treatment, and that time is part of the price. Where earlier filler is present, ultrasound assessment shows where it is before anything more is added.
Doctor time is also spent before any injection. The eyes are examined at rest, looking up and in different lights, because shadows change with light. Earlier treatments are recorded, and any history of puffiness, allergy or fluid retention is asked about. This assessment is what separates a good candidate from a poor one, and it is the part most often skipped when the price is low.
“Under the eyes, the most valuable thing I sell is restraint. Sometimes the right amount of filler is none.”
If the fullness under your eye is bulging orbital fat, filler will usually make the bag look bigger. If the dark colour is pigment, filler will not lighten it. If the main issue is crepey, thin skin, filler may make it look worse. And if you tend to retain fluid around the eyes, a hydrophilic product can cause persistent puffiness; delayed swelling and nodules are among the complications reported after tear trough filler.
In each of these cases, the better use of money is a different treatment: an eye bag assessment and, where appropriate, a surgical opinion; pigment treatment for dark circles; or a skin-quality approach such as polynucleotides for thin skin. Being told so before treatment is the most valuable part of the consultation. Each of these routes has its own cost, explained in its own guide.

Because the volumes are small and the area moves relatively little, soft hyaluronic acid filler under the eyes can last longer than in more mobile areas, though duration varies. Many people need only a small top-up much later, or none. That makes the long-term cost of a well-judged treatment modest compared with the first visit.
The expensive path is the opposite one: too much product, puffiness that needs dissolving, a waiting period, and then retreatment. Each step has its own cost and its own recovery. Paying for careful assessment, a conservative amount and a planned review is usually the lower-cost route over the years, as well as the safer one.
The under-eye area often has more than one problem. A hollow may sit alongside thin skin, fine crepe or pigment, and filler addresses the hollow only. Thin skin may benefit from a polynucleotide course, crepe from energy-based or laser treatment, and pigment from a pigment plan. If more than one is needed, the order and spacing matter, so that swelling from one treatment does not hide the result of another.
A combined plan should list each part separately, with its cost and timing, so you can decide which matters most to you and do it first. It is entirely reasonable to treat the hollow and stop there, or to address skin quality first and decide on filler later.
A fair quote names the product, states the planned amount for each side, describes the technique and says who will inject. It should say whether ultrasound assessment is needed, what numbing is used, when the review will be and how a small adjustment at review is charged. It should also explain what happens if correction with hyaluronidase is ever needed, and whether that is charged separately.
It is also reasonable to expect the risks to be discussed in plain terms: bruising and swelling are common, a bluish tint can appear if product sits too superficially, delayed puffiness can occur, and serious vascular events, though rare, are possible. A quote that does not mention any of these is incomplete. It should also tell you how to reach the clinic in the days after treatment, and which symptoms, such as increasing pain, a change in skin colour or any change in vision, need urgent attention rather than waiting for review.
A full syringe as the default. Under the eyes, more is rarely better. A non-hyaluronic acid product under the eye. Products that cannot be dissolved are a poor choice in an area where correction may be needed. Very cheap filler of unknown origin. Unregistered products cannot be traced if something goes wrong; see HSA registration explained.
No assessment of bags versus hollows. Injection by a non-doctor. Prepaid top-ups sold on the day. A top-up should be decided at review, after swelling has settled, not before treatment. Ask, too, whether the clinic keeps hyaluronidase on site and has a plan for urgent complications. More in aesthetic clinic red flags.
Dr Sin Yong carries out every under-eye assessment personally. He examines the eyes in different lights and positions, distinguishes a hollow from a bag, checks for fluid tendency and earlier filler, and decides whether filler suits you. If it does, he plans a small amount of a soft hyaluronic acid filler placed deep with a cannula, as described on the tear trough refinement page.
You receive a written quote that states the product, planned amount, technique, numbing, review and how any adjustment or correction is handled. Nothing is added on the day without your agreement. For alternatives, read under-eye filler vs Rejuran for the eyes and the under-eye filler guide.
It depends on the product, the amount needed, the technique, whether ultrasound assessment is required and how review is handled. Under the eyes the amounts are small, so assessment and skill account for much of the cost. At IN Eternity Clinic, Dr Sin Yong gives a written quote after examining your eyes.
Because the right amount is usually small, and per-ml pricing can encourage using more than needed. Opened syringes are single-use, so many clinics quote per treatment. Ask how much product is planned for each side and what the price includes.
Soft hyaluronic acid filler under the eyes can last longer than people expect because the area moves relatively little. Duration varies between people and products. Top-ups are decided at review rather than on a fixed schedule. Many people need only a small amount, if any, much later.
Hyaluronic acid filler can be dissolved with hyaluronidase, a prescription medicine. The quote should explain how correction is handled and whether it is charged separately. This reversibility is one reason hyaluronic acid is preferred under the eyes. Correction is done in small, staged amounts.
No. People with bulging fat bags, marked fluid retention, very thin crepey skin or pigment-driven dark circles are often better served by other treatments. Dr Sin Yong will tell you at assessment if filler is not the right choice. In that case, a more suitable option is explained.
They may use more product than needed, a firmer or unregistered filler, a quicker needle technique, or skip assessment and review. Ask for the product name, planned amount, technique, who injects and what review is included. A low price for the wrong product or technique is poor value.
There should be. Swelling can mask the true result for a week or two, so review is planned after it settles. The written quote at IN Eternity Clinic explains when review takes place and how any small adjustment is charged.
