Forehead Filler in Suwon: What Else Should Be Considered When Creating a Rounded Forehead?

If your forehead looks wide and flat from the front, or if the line between your forehead and the bridge of your nose looks angled from the side, it is worth first checking the curve of the frontal bone and the extent of the hollowing. Forehead filler is a treatment that places hyaluronic acid gel in divided amounts in the deep layer between the frontal bone and the muscle to create a curve in a flat or hollow forehead.
How rounded the forehead becomes is not decided by the amount of filler alone. We need to consider how the side profile curve connects to the bridge of the nose, whether the temples are also hollow, how much the forehead muscles move, and where the blood vessels run, so that the forehead does not look like it is sticking out on its own. At our Suwon clinic, we take photos before treatment, design the area to be filled, and then decide the type and amount of filler.
In this article, we go through why foreheads look flat, how to tell which concerns are handled by forehead filler and which by other methods, how forehead filler is placed and the treatment steps, duration and care, and side effects.
Forehead Filler: Key Points
- The shape of the forehead is determined first by the curve of the frontal bone, and with age, fat and skin thickness decrease, making hollowing more noticeable.
- Volume that looks empty is addressed with filler, while horizontal wrinkles caused by muscle movement are mainly addressed with Botox.
- Forehead filler is spread widely in divided amounts in the deep layer above the bone, and areas where blood vessels run, such as the inner area above the eyebrows, are handled with particular care.
- We describe the duration as 6 to 12 months depending on the area, product, and individual, and you should avoid pressure on the forehead for 2 to 3 weeks.
Why does the forehead look flat or hollow?
The shape of the forehead is determined first by the curve of the bone. If the frontal bone slopes gently backward or the area above the brow bone is concave, the forehead looks wide and flat from the front, and the line between the bridge of the nose and the forehead looks angled from the side.
With age, the fat and skin thickness of the forehead also decrease, making the concave area above the eyebrows and hollow temples more noticeable. Horizontal wrinkles that fold across the forehead, by contrast, form as the forehead muscles move repeatedly, so when hollowing and wrinkles occur together, their causes need to be considered separately.
Concerns addressed by forehead filler and concerns better suited to other methods
The treatment that addresses a forehead concern depends on its cause. When several causes are mixed, treatment may be planned in separate stages.
| Concern | Cause | Main approach |
|---|---|---|
| Flat or hollow forehead | Frontal bone curve, loss of volume | Fill volume with forehead filler |
| Concave area above the brow bone | Contour of the bone | Forehead filler spread thinly |
| Horizontal forehead wrinkles | Repeated contraction of the forehead muscles | Mainly Botox |
| Hollow temples | Decrease in fat and skin thickness | Consider temple volume as well |
For men, a prominent brow bone with a forehead that slopes gently backward tends to suit the face, so rather than making the whole forehead round and upright, we plan only to fill the concave area above the brow bone and the hollow in the middle of the forehead. When combined with Botox, we may first reduce muscle movement and then decide the amount of filler.

How is forehead filler placed, and how is the degree of roundness decided?
How forehead filler is placed
The forehead is a large area that moves a lot throughout the day, so instead of concentrating filler in one spot, we spread it widely in divided amounts. The filler is placed in the deep layer above the bone and spread evenly to smooth the edges, and if the skin is thin, the edges of the filler may show through, so it is spread thinly in a deeper layer. Blood vessels connected to those leading to the eyes run through the inner area above the eyebrows, so this area is handled with particular care.
Adding more filler does not make the curve better. If the forehead projects too far forward relative to the length of the face and the height of the nose, it can look unnatural, so we first agree on a target curve by looking at where the highest point of the forehead falls in profile and whether the line down to the bridge of the nose flows without a break.

Recovery and Shape Care After Forehead Filler
- You may wash your face and wear makeup starting 2 to 3 hours after treatment, and the DuoDERM patches on the injection sites are removed after 1 to 3 days.
- For 3 to 7 days after treatment, avoid heavy drinking, smoking, saunas and Korean bathhouses, hot baths, and strenuous exercise.
- Take the prescribed medication consistently for 3 days to prevent inflammation and relieve pain.
- For 2 to 3 weeks, avoid anything that presses on or stimulates the treated area, such as wearing hats, sleeping face down or on your side, wearing glasses, ultrasound and radiofrequency treatments, facial meridian massage, and dental treatment.
Right after injection, the forehead may look more rounded than planned because of swelling, and as the swelling subsides, the filler blends with the tissue and the shape settles. If you are unhappy with the shape or a problem arises, it can be dissolved with an enzyme that breaks down hyaluronic acid (hyaluronidase); once the enzyme is injected, the filler is gradually broken down and absorbed over about 24 to 48 hours.
Forehead Filler Side Effects and Precautions
Bruising, swelling, pain, or a foreign-body sensation may occur at the injection sites, and most subside within 1 to 2 weeks. The filler's shape may look different when you make expressions or when the forehead is pressed, and swelling and recovery speed vary from person to person depending on forehead structure and skin condition.
Rarely, nerve damage, allergic reactions, or inflammation may occur. If filler blocks a blood vessel, skin necrosis can occur, and if a vessel leading to the eye is blocked around the eyes, such as between the brows, there is a risk of decreased vision or vision loss, so we limit the depth and amount where blood vessels run. Please be sure to tell us before treatment if you have a medical history such as antibiotic allergies, have previously had forehead filler or fat grafting, or are taking blood-thinning medication.
If pain keeps getting worse even after taking the prescribed medication, if the skin changes color, if blisters, itching, or a feeling of heat persist, or if your vision becomes blurry, please contact the clinic right away.
What should be checked before forehead filler?
If any of these apply, start with a forehead curve assessment
- From the side, the line between my forehead and the bridge of my nose looks angled.
- From the front, my forehead looks wide and flat.
- The area above my eyebrows or my temples are concave and hollow.
- I also have horizontal wrinkles on my forehead.
If two or more apply, it is best to first check whether the hollowing is due to the bone curve, loss of volume, or the muscles. Whether to proceed with treatment, as well as the method and extent, is decided together during consultation after a medical examination.
In short, the key to forehead filler is looking at the side profile curve, temples, muscles, and blood vessels together, deciding on the target curve first, and then adjusting the amount.
FAQ
Q. Is forehead filler very painful?
A. Treatment is done with numbing cream or local anesthesia, so most people feel only a prick and a dull, pressing sensation. The areas above the eyebrows and near the hairline are more sensitive than the middle of the forehead, and for a day or two after treatment it may feel sore when pressed.
Q. How long does forehead filler last?
A. We describe it as 6 to 12 months depending on the area, product, and individual. Avoiding hats that press on the forehead and sleeping face down for 2 to 3 weeks helps reduce changes in shape, and a touch-up is decided after bruising and swelling have subsided.
Q. Do men get forehead filler too?
A. Men also get forehead filler. For men, a prominent brow bone with a forehead that slopes gently backward tends to suit the face, so rather than making the whole forehead round and upright, we plan only to fill the concave area above the brow bone and the hollow areas.
Q. How many cc of forehead filler do I need?
A. It depends on the area to be filled, the depth of the hollowing, and skin thickness. Domestic fillers come in 1cc, 3cc, and 5cc options, and we sometimes start by shaping the curve with a small amount and then add more after the swelling goes down.
Q. Can forehead filler be reversed if I don't like the shape?
A. Hyaluronic acid filler can be dissolved with hyaluronidase, a dissolving enzyme. Once the enzyme is injected, the filler is gradually broken down and absorbed over about 24 to 48 hours, and the timing for re-injection is decided during consultation after the swelling has subsided.
Q. How can I find out the cost of forehead filler?
A. The cost depends on the type and amount of filler. We let you know after confirming during consultation whether to use domestic or imported hyaluronic acid filler and how much to inject, and you can also see the items for each option on the treatment information page.
