Dermal Fillers in Singapore

Dermal fillers in Singapore are gels injected under the skin to restore support where the face has lost volume or never had much projection. Most of them today are made of cross-linked hyaluronic acid (HA), a sugar molecule that the body already makes in skin and joints. Cross-linking ties the HA chains together so the gel holds its shape for longer than natural HA, which the body clears within days.

Filler is a medical procedure. At SkinRev Lab we do not inject anything; dermal fillers are performed by Dr Sin Yong at IN Eternity Clinic, after a face-to-face assessment. The same family of HA gels is used for different jobs: firm, high-lift gels for the chin and cheekbones, softer gels for the temples and under-eyes, and very fluid gels for fine surface work. Choosing the gel is as important as choosing the area.

A useful way to think about dermal fillers is that they replace structure rather than fill lines. As we age, bone along the eye socket, cheek and jaw slowly recedes, and the deep fat pads shrink and slide. Lines and folds often appear because the support above them has gone. Putting a small amount of HA back where support was lost tends to look more natural than pushing filler directly into a crease.

How it works

The mechanism,
in plain English

HA is hydrophilic: it binds water. Once placed, the gel occupies space and draws in a little fluid, which is why the area can look slightly fuller for the first few days before it settles. Two properties decide how a gel behaves. Firmness (the elastic modulus, G', measured in pascals) tells you how well it resists pressure and lifts tissue, so higher-G' gels are used on bone. Cohesivity tells you whether it stays as a bolus or spreads. Many volumising gels contain about 20–25 mg/mL of HA, often mixed with a small amount of local anaesthetic (lidocaine).

Placement depth matters. Structural gels are usually laid on the bone (supraperiosteal) with a needle, or in deep fat compartments with a blunt cannula. Softer gels go into the subcutaneous fat. The arteries of the face run in predictable but variable paths, and an injection inside or against an artery is the cause of the most serious filler complication, vascular occlusion. That is why detailed anatomy knowledge, slow low-pressure injection, small aliquots and, where useful, high-frequency ultrasound to map vessels and old filler are part of safe practice. HA can be broken down with an enzyme, hyaluronidase, which is a key safety advantage over fillers that cannot be dissolved.

“Filler works well when it rebuilds lost structure in the right layer; it is a poor tool for chasing every line.”

Is it right for you

Who it suits,
and who it does not

Dermal fillers usually suit adults with a specific, visible loss of support: a short or receding chin, a flat midface, hollow temples, a deep tear trough with good skin quality, or a jawline that has lost definition. They also suit people who want a change they can see in one visit and who accept that HA is broken down gradually at a rate that varies by product and area. People who want refinement rather than transformation tend to be happiest with filler.

Filler is not advised during pregnancy or breastfeeding, over active skin infection, cold sores or acne at the site, or soon after dental work or another procedure in the same area. People with a history of severe allergy, autoimmune disease, or previous reactions to filler need careful review first. Filler is a poor fit for loose, heavy skin, where tightening or lifting usually does more, and for puffy under-eyes caused by fat bulging forward. If you already have a lot of filler from past treatments, the honest first step may be assessment or dissolving, not more volume.

What to expect

Consultation, session
and aftercare

Your first visit is a consultation with Dr Sin Yong at IN Eternity Clinic. He looks at your face at rest and in motion, checks your medical history and any previous fillers, and explains which areas would help, which would not, and the risks. Photographs are taken for your record. If treatment goes ahead, the skin is cleaned thoroughly, numbing cream may be used, and the filler is placed in small amounts with either a fine needle or a blunt cannula.

Afterwards, expect some swelling, tenderness and possible bruising, usually settling over several days. Avoid heavy exercise, saunas, facial massage and pressing on the area for a day or two, and do not lie face-down on treated areas that night. Any pain that is getting worse, skin turning pale, blotchy or dusky, or any change in vision is an emergency: contact the clinic straight away. A review is usually arranged a few weeks later, once swelling has settled, to judge the result.

What the research says

The evidence,
with sources

Hyaluronic acid fillers have a favourable safety record, but adverse events do occur. An international consensus group reviewed the evidence and found that most reactions are mild and short-lived, such as swelling, bruising and tenderness, while serious events are rare. The group stressed that detailed facial anatomy, careful patient and product selection and sound technique reduce risk, and that clinicians must be ready to treat complications if they arise. Ultrasound adds another layer: it can show earlier filler, map vessels before injection and guide hyaluronidase straight into a problem deposit.

The most feared complication is blindness from filler entering an artery that connects to the eye's blood supply. A review of world literature found the nose, glabella (between the brows), forehead and nasolabial fold were the most frequent sites, and that HA was the filler involved in most reported cases; no treatment was consistently successful once it happened. Separately, MRI follow-up of midface HA filler has shown gel still present years after injection, which is a reason to be conservative with repeat treatments and to keep a record of what was used.
