Hyaluronic acid dermal fillers
HA filler · dermal filler · 'fillers' · Juvéderm, Restylane, Belotero and other brands
'Dermal fillers Singapore' is one of the most-searched aesthetic terms in the country, and the conversation has shifted from 'should I' to 'how much', 'which brand' and 'what if it migrates'. Dissolving old filler is now almost as common a request as placing new.

Do Hyaluronic acid dermal fillers work?
Established. Placed deep, in the right compartment, by someone who can dissolve it, HA filler is the most reversible structural tool in aesthetics. The problems come from the under-eye, from top-ups without reassessment, and from anyone who cannot name the artery they are avoiding. A long record of randomised, controlled, blinded trials supports HA filler for nasolabial folds, midface volume and lips, with results persisting one to two years in the pivotal midface study.
- Verdict
- Established Long clinical track record. Results depend on selection and technique more than on the device.
- Evidence base
- 5 PubMed-indexed studies cited below, including systematic reviews, meta-analyses, randomised trials.
- Suits
- Volume loss in the midface, temples, chin and jawline; lips and lines in people who want a reversible, immediate result; structural support placed deep by an injector who assesses the whole face.
- Not for
- The under-eye in most faces (see the under-eye filler review), people chasing a shape their bone structure does not support, anyone who cannot accept bruising or a dissolve-and-redo if the result is wrong, and repeated top-ups without reassessment.
- In Singapore
- HA fillers are HSA-registered medical devices injected only by registered medical practitioners in licensed clinics; salons and 'home injectors' are outside the law.

What it is
Hyaluronic acid fillers are gels of cross-linked hyaluronic acid, a sugar molecule found naturally in skin, injected to restore volume, support structure or smooth lines. They differ in firmness, cohesivity and how much water they draw, which is why the same brand family has a dozen products for different depths and areas. Unlike biostimulators, their effect is immediate and they can be dissolved with hyaluronidase.
How it works
The gel occupies space where fat or bone has receded — the midface, temples, chin, jawline, lips — and, placed deep on bone, can project or lift adjacent tissue. It integrates over days, draws some water, and is gradually broken down over roughly six to eighteen months depending on product, site and movement. Placement plane and product choice decide whether a result looks like structure or like filler.
What the evidence says
A long record of randomised, controlled, blinded trials supports HA filler for nasolabial folds, midface volume and lips, with results persisting one to two years in the pivotal midface study. Meta-analyses in 2022 and 2024 confirm efficacy for the nasolabial fold and show lidocaine-containing products are as effective and more comfortable. The serious complication is vascular occlusion — filler blocking an artery — which can cause skin loss and, rarely, blindness; world literature reviews count hundreds of cases, concentrated in the nose, glabella and forehead. High-dose pulsed hyaluronidase protocols exist for this emergency, which is the main reason HA, not an irreversible filler, is the default choice.

What the studies show
- RCT
In a blinded randomised trial of midface volumising HA filler, improvement was maintained at two years in a majority of treated subjects, with injection-site reactions the main adverse events.
Volumizing hyaluronic acid filler for midface volume deficit: 2-year results from a pivotal single-blind randomized controlled study. — Dermatol Surg, 2013. PMID 24093664.
- meta-analysis
Pooled randomised trials showed HA fillers improve nasolabial fold severity with lidocaine formulations equally effective and less painful; adverse events were mostly mild and transient.
Efficacy and Safety of Hyaluronic Acid Fillers With or Without Lidocaine in the Treatment of Nasolabial Folds: A Systematic Review and Meta-Analysis. — Aesthetic Plast Surg, 2024. PMID 39014236.
- systematic review
The world literature to 2018 recorded 146 new cases of filler-related vision loss, most after injection of the nose, glabella and forehead; HA was the commonest filler involved and few cases recovered vision.
Update on Avoiding and Treating Blindness From Fillers: A Recent Review of the World Literature. — Aesthet Surg J, 2019. PMID 30805636.
- clinical protocol
Repeated high-dose hyaluronidase given hourly until clinical reperfusion resolved impending skin necrosis from HA filler occlusion in the reported series, establishing the emergency protocol now widely taught.
New High Dose Pulsed Hyaluronidase Protocol for Hyaluronic Acid Filler Vascular Adverse Events. — Aesthet Surg J, 2017. PMID 28333326.
- review
Early adverse events are mostly injection-related and self-limiting; delayed nodules, infection and vascular compromise are rarer but require specific management, and product reversibility matters for all of them.

Who it suits
Suits
Volume loss in the midface, temples, chin and jawline; lips and lines in people who want a reversible, immediate result; structural support placed deep by an injector who assesses the whole face.
Not for
The under-eye in most faces (see the under-eye filler review), people chasing a shape their bone structure does not support, anyone who cannot accept bruising or a dissolve-and-redo if the result is wrong, and repeated top-ups without reassessment.
Alternatives
The two reviewed treatments most often weighed against Hyaluronic acid dermal fillers, on the same standard.
| Hyaluronic acid dermal fillers | Masseter slimming injections | Preventive 'baby' neuromodulators | |
|---|---|---|---|
| Verdict | Established | Established | Established |
| What it is | Hyaluronic acid fillers are gels of cross-linked hyaluronic acid, a sugar molecule found naturally in skin, injected to restore volume, support structure or smooth lines. | Botulinum toxin, a prescription medicine, injected into the masseter, the thick chewing muscle at the angle of the jaw. | Smaller doses of botulinum toxin, a prescription medicine, placed to soften muscle movement without freezing it, used earlier in life to slow the etching of dynamic lines into static ones. |
| Evidence base | 5 PubMed-indexed studies cited below, including systematic reviews, meta-analyses, randomised trials. | 4 PubMed-indexed studies cited below, including systematic reviews, randomised trials. | 3 PubMed-indexed studies cited below, including systematic reviews. |
| Suits | Volume loss in the midface, temples, chin and jawline; lips and lines in people who want a reversible, immediate result; structural support placed deep by an injector who assesses the whole face. | A genuinely bulky masseter that squares the lower face, and clenchers or grinders who cannot tolerate a splint. | Expressive foreheads and crow's feet beginning to leave resting lines; people who want movement preserved. |
| In one line | Placed deep, in the right compartment, by someone who can dissolve it, HA filler is the most reversible structural tool in aesthetics. The problems come from the under-eye, from top-ups without reassessment, and from anyone who cannot name the artery they are avoiding. | The jaw is a muscle you use a thousand times a day; weaken it as much as the face needs and no more. | With the caveat that natural has a technical definition: movement preserved, proportions unchanged. |
Risks
Bruising, swelling and asymmetry; lumps and migration; delayed nodules; infection; vascular occlusion causing skin loss or, rarely, blindness. Risk tracks the site, the plane and the injector more than the brand.
In Singapore
HA fillers are HSA-registered medical devices injected only by registered medical practitioners in licensed clinics; salons and 'home injectors' are outside the law. A clinic injecting HA should hold hyaluronidase on site and be able to show it. Fees are quoted at consultation and are not advertised.
