My forehead looks flat and sunken. Which treatment fits?
“From the side, my forehead is flat.” “The middle of my forehead dips and casts a shadow.” That is usually how people ask about forehead volume. But a forehead concern often mixes two kinds of lines in with the volume, so I separate those first.
The short answer
A flat forehead or a dip in the middle is a volume problem under the skin, so I set the shape first with dissolvable hyaluronic acid filler, and if a broad base of support is needed, add a collagen booster such as Juvelook Volume100. Fine lines and texture sit in the dermis, so Juvelook Skin or a skin booster handles them; horizontal lines that appear when you raise your brows are Botox territory. The forehead is an area where vessels call for care, so I do not inject a lot at once; I split it across visits. At Miso Clinic in Daegu I look at your profile and your expressions together and decide which comes first: volume, fine lines or expression lines.
Forehead concerns mix three things
| Concern | Type of treatment | Miso Clinic pairing | What to expect and the limits |
|---|---|---|---|
| Flat, or a dip in the middle | Hyaluronic acid filler + collagen booster | Shape first with hyaluronic acid filler + Juvelook Volume100 | Filler fills at once and can be dissolved. Volume100 supports over weeks to months |
| Fine lines and skin texture | Dermal collagen booster or skin booster | Juvelook Skin or Rejuran | Works on texture; cannot build volume |
| Horizontal lines when raising the brows | Muscle injection | Botox | Lines in motion ease a lot, but marks that stay at rest change less |
| Deep marks that stay at rest | Botox + dermal treatment | Botox + Juvelook Skin | They do not disappear in one go |
In front of a mirror, look at your profile once with a relaxed face, and once with your brows raised as far as they go. If the line looks flat or dipped from the side, it is volume; if lines appear just when you raise your brows, they are expression lines. Many people have both.

Why set the shape of a flat forehead with filler first?
The forehead is a broad surface, so even small unevenness looks bumpy when light hits it. That is why I first set a rounded line with dissolvable hyaluronic acid filler. It fills straight away, so we can check and adjust the shape together on the spot, and if you do not like it, a dissolving injection can reverse it.
If you also want to support a base that has thinned over a wide area, I think about Juvelook Volume100 next. It is a formulation placed under the skin, and the manufacturer lists the forehead as one of its uses. Right after injection it looks full because of the hyaluronic acid, then at about 2–3 weeks it briefly looks as it did before, and after that collagen builds support over weeks to months. I do not judge results during that stretch. It belongs to a group with no dissolving injection, so we start small.
If the temples have hollowed too, filling the forehead alone can make the upper face look odd. The side line of the forehead runs into the temples, so we look at both.

Is forehead filler risky?
To be honest, the forehead is an area that needs care. In a literature review of 365 new reports of vision loss after filler, the forehead made up 27.7%, second after the nose. It is rare, but when it happens the outcome is serious, so I always explain it before treatment.
- I do not inject a lot at once; I split it. We look again after 2 weeks and decide whether to add more.
- At first I use dissolvable hyaluronic acid filler. Hyaluronidase breaks down hyaluronic acid alone; there is no antidote for collagen boosters.
- If the skin turns white or blotchy during or right after treatment, your vision seems wrong, or pain keeps getting worse, tell us at once.

The pairings I suggest first
- A flat profile with clear hollowing → shape first with hyaluronic acid filler, then Juvelook Volume100 a month or two later if the base still feels lacking
- Mild hollowing, thin forehead skin, many fine lines → Juvelook Skin or Rejuran
- Lines when raising the brows are the main concern → Botox, always kept a little on the light side for the forehead
- Hollowing and expression lines together → Botox first, then 2 weeks later, once expressions have settled, we decide how much to fill
If forehead Botox blocks too hard, the brows can drop and the eyes feel heavy. The frontalis is the one muscle that lifts the brows. So I often choose to leave a little of the line.

When I see it differently
- If the shape of the forehead bone itself is flat, injections can change little. Changing the bone is a plastic surgery matter.
- If a sagging forehead has brought the brows down, I look at the sagging before filling.
- If you do not know what filler was used before, we check that first. Material that does not dissolve may still be there.
- With pregnancy or breastfeeding, or inflammation in the area, we do not treat that day.

How does the consultation work, and how do I book?
On a first visit we take photos from the front, at 45 degrees and from the side, and together we pick the one concern that bothers you most. I'll ask about any medications you take, any metal or electronic implants in your face, and whether you might be pregnant, and then I split things into what we can do today and what can wait for later. It's completely fine to come in just for a consultation and go home.

Forehead volume treatment: FAQ
For a flat forehead, is filler or Juvelook the right fit?
If the shape needs setting right away, dissolvable hyaluronic acid filler comes first. If a broad base of support is needed, Juvelook Volume100 is added after.
I heard forehead filler is risky. Is it?
The forehead is an area where vessels call for care. Of 365 vision loss reports, the forehead made up 27.7%. So I split the amount and start with filler that can be dissolved.
It has been 2 weeks since Juvelook Volume and my forehead looks sunken again.
At about 2–3 weeks the hyaluronic acid is absorbed and the area briefly looks as it did before. Collagen builds support over the following weeks to months, so I do not judge at this point.
Can filler smooth forehead lines too?
Lines that appear when you raise your brows are Botox first. For marks that stay at rest, we discuss adding a dermal treatment.
Can the forehead and temples be filled together?
Yes. The side line of the forehead runs into the temples, so if the temples have hollowed too, treating both looks more natural. We split the amounts.
Where can I get a forehead volume consultation in Daegu?
At Miso Clinic in Daegu (4F Bombom Building, 125 Dongdeok-ro, Jung-gu, Exit 1 of Kyungpook National University Hospital Station). You can book through Naver booking, KakaoTalk or by phone at +82-53-428-2700. Weekdays 11:00–19:00, Saturday 10:00–16:00, closed Sundays and public holidays.
