Forehead Fillerin Gangnam, Seoul
Forehead filler uses hyaluronic acid (HA) to shape the forehead — rounding a flat or uneven surface and creating a smoother, gently convex side profile. It is often chosen to soften bumps and dips, or to add a soft curve to the upper face. The gel is placed deep, against the bone below the forehead muscle, where it is least likely to show irregularities. The forehead has nerves and vessels near the brow, so injection points and depth are chosen carefully. At QD Clinic in Gangnam, Seoul, South Korea, a session usually takes about 20–40 minutes with little downtime. (Results vary by individual.)
Who it’s for
- A flat forehead you would like to round out
- An uneven forehead with bumps or dips
- A wish for a softer, more convex side profile
- Anyone wanting a smooth curve linking the forehead to the temples
The forehead is a broad surface and usually needs a larger, gradual approach for an even result. Injection depth is kept deep to reduce irregularities. Suitability is confirmed during consultation.
How it works
HA filler adds volume where it is placed and is gradually absorbed over time. On the forehead, the doctor typically places the gel deep — against the bone, below the frontal muscle — because this plane gives a smoother surface and reduces the chance of visible lumps. A cannula or a careful needle technique spreads the gel evenly across the broad surface, and injections are kept away from the nerves and vessels near the brow. Building the volume gradually helps the forehead round out without looking overfilled. HA can be dissolved with hyaluronidase if an adjustment is needed. (Results vary by individual.)
THE MECHANISM, STEP BY STEP
01Water-holding volume
Hyaluronic acid occurs naturally in the skin and binds water, so the gel adds soft volume that rounds the surface where it is placed.
02Placed deep, spread evenly
On the broad forehead the gel sits deep against the bone below the frontal muscle — a plane that gives a smoother surface — and is spread with a cannula or careful needle, away from the nerves and vessels near the brow.
03Immediate but temporary
The shape shows the same day because the gel fills the space; over the following months the body gradually breaks the HA down, so the effect is not permanent.
04Adjustable and reversible
Because it is HA, the result can be added to gradually, or dissolved with an enzyme (hyaluronidase) if an adjustment is ever needed.

- Avoid pressing or resting firmly on the forehead, and skip saunas and intense exercise for a day or two as we advise.
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
DAY 0 Treatment day
The forehead looks rounder immediately. Mild swelling, redness or tenderness is common, and early unevenness can show before it settles.
DAY 1-3 Early settling
Most swelling eases and any bruising begins to fade. Makeup and normal skincare can usually resume as advised.
WEEK 1-2 Settled result
Swelling resolves, any early unevenness smooths and the front and side profile become clear. (Results vary by individual.)
12-18 MONTHS Duration
HA in this broad, low-movement area often lasts around 12–18 months, varying with the product and your metabolism. (Results vary by individual.)
TOP-UP Review & maintenance
Your doctor reviews the result and, if appropriate, discusses timing for a top-up based on your face.
Sessions & results
Shape appears right away and settles over about 1–2 weeks. Because the forehead is a broad, low-movement surface, HA here often lasts around 12–18 months, though this varies with product and metabolism. A top-up can be considered at consultation. (Results vary by individual.)
How it compares
These all add or build volume to shape the forehead, but they work in different ways and suit different goals. The right choice is decided after we assess your face.
| Comparison | Forehead Filler | Collagen-stimulating filler | Fat Grafting |
|---|---|---|---|
| Agent | Hyaluronic acid (HA) gel | Calcium hydroxylapatite or poly-L-lactic acid | Your own fat, transferred surgically |
| What it does | Rounds and smooths the surface straight away | Prompts your own collagen to build volume gradually | Adds volume with transferred fat; part of it may persist |
| Onset | Immediate; settles over about 1–2 weeks | Gradual over weeks to months | Some volume at once; final after healing |
| Duration | Around 12–18 months (varies) | Often longer, up to about 2 years (varies) | Variable; a portion can be long-lasting |
| Reversible? | Yes — dissolvable with hyaluronidase | No specific dissolver | Not readily reversible |
| Downtime | Little; temporary swelling or bruising | Little; similar injection reactions | More; a minor surgical procedure |
Neither is “better” — they work differently and suit different goals. The right choice is decided after we assess your skin.
Safety & considerations
Possible reactions
- Temporary swelling, redness or a feeling of fullness
- Tenderness or bruising at the injection points
- Early unevenness or small lumps, which usually settle or can be smoothed
- Very rarely, filler affecting a blood vessel — this needs prompt medical attention
When to take extra care
- Pregnancy or breastfeeding — let us know at consultation
- Active skin infection, inflammation or a breakout in the treatment area
- A known allergy to hyaluronic acid or lidocaine
- Previous filler, threads or surgery in the area — tell your doctor so placement can be planned
- A bleeding tendency or blood-thinning medication — tell your doctor
Whether forehead filler suits you, and the right amount, are confirmed during consultation. Effects and their duration vary by individual, and side effects may occur. We explain the warning signs — unusual pain, skin turning pale or dusky, or any vision change — so you know to contact us promptly.

Frequently asked questions
No. Filler adds volume to shape and round the forehead surface, while botulinum toxin relaxes the muscles to soften lines that form when you move your brow. They address different goals, so a flat or uneven forehead and expression lines call for different approaches. When both are present, the two are sometimes combined.
To reduce irregularities, the gel is placed deep against the bone, below the forehead muscle, and spread evenly across the broad surface. Building the volume gradually also helps the forehead round out without looking overfilled. Any early unevenness usually smooths as swelling settles over one to two weeks, and HA can be adjusted if needed.
The forehead is numbed with a cream first, and many HA fillers contain a local anaesthetic. Because the forehead is broad, the gel is spread over a wider area than in most fillers, so the session usually takes about 20–40 minutes and most people feel pressure rather than sharp pain. Injection points are chosen to stay away from the nerves and vessels near the brow.
The forehead is a broad surface, so it can need more product than a small zone such as the lips or nose. How much depends on how flat or uneven your forehead is and on the profile you want. We decide the amount after assessing your shape and profile, and build it up gradually rather than filling it all at once.
The shape appears right away and settles over about one to two weeks. Because the forehead is a broad, low-movement surface, HA here often lasts around 12–18 months, though this varies with the product and your metabolism. A top-up is considered only after we review how the contour has held.
The aim is a soft, continuous line running from the forehead down to the nose when your face is seen in profile. It is not about doming the whole forehead upward; we look at the hollow areas together with the areas that already project, and work on the transition between them. If you show us a photo of the profile you have in mind, we will go through it and tell you separately what is within reach and what would be difficult.
We first check whether assessment and any necessary follow-up fit your stay. Share your arrival, departure and important event dates before booking. For this treatment, the expected course is as follows. Shape appears right away and settles over about 1–2 weeks. Because the forehead is a broad, low-movement surface, HA here often lasts around 12–18 months, though this varies with product and metabolism. A top-up can be considered at consultation. (Results vary by individual.) Temporary swelling, redness, tenderness or bruising may occur and usually settles within about 1–2 weeks. Avoid pressing or resting firmly on the forehead, and skip saunas and intense exercise for a day or two as we advise. Examination may lead to postponement or additional visits. Confirm contact arrangements after returning home and when in-person medical care may be needed. What the doctor checks first for this treatment: “The curve of the forehead and how it joins the brow and the bridge of the nose”.
