Forehead filler
forehead contouring filler · forehead augmentation · 'rounded forehead'
A rounded, convex forehead is a beauty ideal in parts of East Asia, and forehead filler is marketed widely in Seoul and Singapore — usually without mention that it is one of the higher-risk filler sites.
Search interest: about 150 searches a month in Singapore for “forehead filler” (Ahrefs, October 2026).
A shape change sold as routine, in a zone the blindness literature names repeatedly. If done at all: hyaluronic acid, deep, slow, small volumes and an injector who can dissolve it immediately.

Is forehead filler worth it?
Caution. A shape change sold as routine, in a zone the blindness literature names repeatedly. If done at all: hyaluronic acid, deep, slow, small volumes and an injector who can dissolve it immediately. Anatomical studies in 2022 and 2025 define safer injection planes and pinch techniques for forehead filler.
- Verdict
- Caution Evidence, regulation or risk profile does not yet support routine use.
- Evidence base
- 3 PubMed-indexed studies cited below, including systematic reviews.
- Suits
- Carefully selected adults who understand the vascular risk and want a modest contour change, treated with reversible hyaluronic acid by an experienced injector with hyaluronidase on hand.
- Not for
- Anyone treating horizontal lines (use neuromodulator), large-volume 'rounding' requests, non-dissolvable fillers in the forehead, and injectors who cannot describe the forehead's vascular anatomy.
- In Singapore
- Forehead filler is offered by doctors in Singapore clinics using HSA-registered fillers.

What it is
Injection of hyaluronic acid or other fillers across the forehead to create a smoother, more rounded contour or to soften a flat or sloping profile. It is a volumising treatment, not a wrinkle treatment; horizontal lines are usually treated with neuromodulators.
How it works
Filler is placed deep, typically in the plane just above the bone beneath the muscle, often with a cannula, and moulded to a smooth curve. Relatively large volumes are needed. The forehead's supratrochlear and supraorbital arteries connect with the eye's circulation, which is the central safety concern.
What the evidence says
Anatomical studies in 2022 and 2025 define safer injection planes and pinch techniques for forehead filler. The 2019 world-literature review of filler blindness lists the forehead among the sites most often associated with vision loss, alongside the nose and glabella. Outcome studies are small and aesthetic; there are no controlled trials showing benefit that outweighs the vascular risk for routine contouring.

What the studies show
- review
Forehead filler safety depends on precise plane selection and knowledge of the supratrochlear and supraorbital vessels; deep supraperiosteal placement is favoured.
Anatomy-Based Filler Injection Techniques for the Forehead. — J Craniofac Surg, 2025. PMID 41066760.
- anatomical study
A pinch technique separates soft tissue from bone to help place filler in a safer plane, but vascular risk is not eliminated.
Pinch Anatomy of Forehead: An Injection Guide for Forehead Filler Treatment. — Facial Plast Surg, 2022. PMID 34983076.
- systematic review
The forehead was among the most common sites associated with filler-related vision loss in the world literature.

Alternatives
The two reviewed treatments most often weighed against Forehead filler, on the same standard.
| Forehead filler | Profhilo | Hyaluronic acid dermal fillers | |
|---|---|---|---|
| Verdict | Caution | Established | Established |
| What it is | Injection of hyaluronic acid or other fillers across the forehead to create a smoother, more rounded contour or to soften a flat or sloping profile. | A high-concentration, stabilised hyaluronic acid injected at five points on each side of the face (the BAP technique), from which it spreads through the tissue. | 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. |
| Evidence base | 3 PubMed-indexed studies cited below, including systematic reviews. | 3 PubMed-indexed studies cited below, including randomised trials. | 5 PubMed-indexed studies cited below, including systematic reviews, meta-analyses, randomised trials. |
| Suits | Carefully selected adults who understand the vascular risk and want a modest contour change, treated with reversible hyaluronic acid by an experienced injector with hyaluronidase on hand. | Crepey, dehydrated skin of the face, neck and hands; people wanting quality not shape; first-time injectable patients. | 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. |
| In one line | A shape change sold as routine, in a zone the blindness literature names repeatedly. If done at all: hyaluronic acid, deep, slow, small volumes and an injector who can dissolve it immediately. | One of the few injectables where 'natural' is built into the design. | 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. |
Risks
Lumps, migration and irregular contour; prolonged swelling; vascular occlusion with skin necrosis; rare blindness or stroke-like events.
In Singapore
Forehead filler is offered by doctors in Singapore clinics using HSA-registered fillers. Because of the vascular risk, hyaluronic acid (reversible) is strongly preferred and hyaluronidase should be immediately available.
