Hello.
I am Dr. Kim Dong-young, Director of Cleor Clinic Hongdae Branch.
Have you ever felt that your forehead looks like an 'M' shape because the sides are indented when you pull your hair back, or that your side profile looks flat because the center is slightly sunken?
"I want to change my hairstyle, but I keep covering it with bangs because of my forehead shape.
Even from the front, my forehead isn't smooth, which makes my impression look plain, and I've been bothered by the fact that the forehead-to-nose line doesn't connect smoothly in my side profile."
These are common concerns for those who request a consultation.
Since the forehead occupies a large area of the upper face, it is a category with various types of shapes.
Whether it is a sunken center, an M-shaped forehead with indented sides, or a generally flat forehead,
everyone has a different forehead shape, so the method of filling volume and the treatment plan are usually determined according to the type.
The Hongdae forehead filler approach involves precisely placing volume according to these shape-specific characteristics.
Today, I will explain how forehead types affect your impression and the characteristics of each brand line for the forehead area.
What is Hongdae forehead filler?
👉 Hongdae forehead filler is a filler procedure that uses a cannula to gently place hyaluronic acid filler according to your forehead type,
restoring natural curves and volume tailored to the characteristics of sunken, M-shaped, or flat foreheads.
The key to forehead procedures is a design tailored to the shape.
Even with the same forehead filler, the location where volume needs to be filled and the required amount vary depending on the forehead shape,
so the pre-treatment forehead diagnosis is a factor that significantly influences the naturalness of the results.
The procedure uses a blunt cannula instead of a sharp needle to place small amounts in safe layers above the forehead bone.
The cannula is known as a tool frequently used in procedures for large areas like the forehead because it allows for smooth and even distribution of the filler.
Characteristics by forehead shape type
👉 Forehead shapes can be broadly divided into three types: sunken center, M-shaped with indented sides, and generally flat,
and each type requires a different approach regarding where and how to fill the volume.
Sunken center forehead
This is a shape where the center of the forehead is slightly indented inward.
Since the forehead-to-nose line does not connect smoothly in the side profile and creates a curve,
the treatment plan is designed to fill the volume in the central area.
M-shaped forehead
This is a shape where both sides of the forehead (above the temples) are indented inward, making the hairline look like an 'M'.
Because the indented areas are prominent when hair is pulled back,
the approach is to fill the volume on both sides of the forehead to smooth out the hairline.
Flat forehead
This is a shape where the entire forehead looks flat without any roundness.
Since the impression looks plain from the front and the profile lacks the forehead curve,
the treatment plan is designed to evenly fill the entire forehead with soft volume.
Mixed type
Mixed types, such as a combination of a sunken center and M-shaped indentations, or a flat forehead with M-shaped indentations, are also frequently observed.
In these cases, different volume placement is required for each area, so this is a category often performed with 4cc or more options.
Hongdae forehead filler treatment design method
👉 The Hongdae forehead filler procedure is a treatment that establishes a plan tailored to the forehead type through four steps: forehead shape diagnosis, checking side and front lines, volume placement by area, and natural line finishing.
Forehead shape diagnosis
This is the stage where we diagnose which type your forehead belongs to and identify where the sunken or indented areas are before the procedure.
It is a process of identifying the type by checking the forehead from the front, side, and oblique angles in front of a mirror and feeling the curves with fingertips.
Checking side and front lines
The naturalness of a forehead filler is difficult to judge by looking at the front line alone.
A balanced treatment plan is established only when checking the curve that connects the forehead-nose-temples in the side profile and the line that connects the forehead-temples from the front.
Volume placement by area
Because the areas requiring volume differ according to the forehead shape type,
the procedure is performed by distinguishing between areas that need filler and those that do not.
Rather than adding excessive volume, precisely placing it only on the curved areas is a factor that influences natural results.
Natural line finishing
The goal after the procedure is to form a forehead line that looks natural from any angle.
The procedure is usually finished with the goal of a smooth line connecting the forehead, nose, and temples in the side profile, and a smooth curve between the forehead and temples from the front.
Characteristics of brand lines for the forehead area
👉 Hongdae forehead filler is operated with domestic, domestic premium (Neuramis), and imported (Belotero, Juvederm) lines,
and each line is an option that shows different textures and usage characteristics in the forehead area.
Domestic line
This line is characterized by an accessible approach and natural volume.
It is a category frequently considered by those who are looking into forehead fillers for the first time or for partial volume filling purposes,
and the 4cc or more option is usually used for covering the entire wide forehead.
Domestic premium Neuramis
This is a brand known for its stable volume among domestic lines.
It features a stable texture that has undergone the BDDE cross-linking process, making it a suitable line for those who want both soft volume and an accessible approach.
Imported Belotero
As a line applied with patented CPM (Cohesive Polydensified Matrix) cross-linking technology,
it has a characteristic that emphasizes a texture that softly integrates into the tissue.
It is known as a category well-suited for placement that naturally permeates wide areas like the forehead.
Imported Juvederm
As a line applied with patented VYCROSS cross-linking technology, it has excellent viscosity and cohesiveness.
It is an option well-suited for placement in areas that require volume support, such as M-shaped indentations, and is considered by those who want relatively long-lasting results.
Hongdae forehead filler lineup
👉 At the Hongdae branch, forehead filler is available in four lines: domestic, domestic premium (Neuramis), and imported (Belotero, Juvederm), with configurations ranging from 1cc options to 4cc or more options that can be selected according to the forehead shape and coverage range.
The 4cc or more option is a line used for covering the entire wide forehead, and the 1cc single option is a category frequently considered for partial volume filling or local area refinement.
The line that suits your forehead shape and coverage range will be discussed during the pre-treatment consultation.
Who is a good candidate for forehead filler?
Those whose side profile looks plain due to a flat forehead
Those who want to refine an M-shaped forehead with indented sides
Those who are bothered by the curves of a sunken center forehead
Those who want a natural curve that connects the forehead-nose-temples line
Those who want to refine their forehead shape to match their hairstyle
Side effects of Hongdae forehead filler and things to know in advance
👉 Although Hongdae forehead filler is a hyaluronic acid filler line with extensive clinical data, it is good to understand in advance that due to the characteristics of the forehead area, the treatment design and the precision of using a cannula are factors that greatly influence the naturalness of the results.
Immediately after the procedure, light redness, minor swelling, or a foreign body sensation may briefly appear in the forehead area.
These are generally reported to resolve naturally within a few days to a maximum of two weeks.
Since the forehead is an area that affects both the side profile and the front impression,
if volume placement is biased to one side, it may look unnatural from other angles.
Excessive volume can create an impression that the forehead looks bloated, so it is important to perform the procedure with an appropriate amount that fits the forehead shape and width.
The forehead area is a region that requires more precise treatment judgment compared to other parts of the face.
For this reason, it is known as a category that ensures stability by using a blunt cannula instead of a sharp needle to gently place small amounts in safe layers above the forehead bone.
In cases of unsatisfactory results or nodules, hyaluronic acid filler is a line that can be reversed with a dissolving enzyme, so there is room for result management.
If any of the following apply to you, please inform us during the consultation as the procedure may be restricted or require prior confirmation.
If you are pregnant or breastfeeding
If you have a history of allergies to hyaluronic acid or lidocaine anesthetic ingredients
If you have active herpes, infection, or wounds in the forehead area
If you have been diagnosed with an autoimmune disease or keloid tendency
If you are regularly taking anticoagulants or antiplatelet agents, or have a bleeding tendency
If you have a recent history of other filler or thread procedures in the forehead area
⚠️ Precautions before and after forehead filler procedure
👉 Forehead filler is a procedure where recovery speed and filler settlement stability vary depending on pre-treatment preparation and post-treatment initial care.
❓ Frequently Asked Questions (FAQ)
Q. Does the required filler volume vary depending on the forehead shape?
It is a category that varies depending on the forehead width and shape type.
In some cases, a 1cc option is sufficient for partial volume filling, while a 4cc or more option is frequently considered if full coverage of a wide forehead is needed, so we will look at the appropriate volume for your forehead condition during the pre-treatment consultation.
Q. Is the treatment method different for M-shaped foreheads and sunken foreheads?
It is a category where the location that needs to be filled with volume is different.
The M-shaped forehead is a method of filling volume in the indented areas on both sides, while the sunken forehead is a method of restoring volume in the central area, so it is a line where the procedure is performed with different plans for each area after shape diagnosis.
Q. Should I choose domestic or imported filler?
Although the ingredients are the same hyaluronic acid, it is a category that differs in texture and maintenance period.
For an accessible approach, the domestic line is considered; for stable volume, the domestic premium Neuramis; for a soft integration texture, the imported Belotero; and for viscosity and cohesiveness, the imported Juvederm.
Q. When can I see the results of the forehead filler?
You can see the line where the forehead volume has been filled immediately after the procedure.
It may look a bit more swollen than the actual result due to initial swelling, and it is reported that a natural line settles over 3 to 7 days.
Q. How long does the forehead filler last?
It is known that the domestic line lasts about 6 to 12 months, and the imported line lasts about 12 to 18 months.
Although the forehead is an area where facial expressions are frequently used, it is a category where maintenance stability is ensured if placed in a safe layer using a cannula.
Q. How much pain is there with forehead filler?
Thanks to the application of anesthetic cream before the procedure and the lidocaine anesthetic ingredient contained in the filler itself, the pain during the procedure is not significant.
It is a line that uses a cannula, so it is less irritating than a sharp needle, and it is a category where tenderness may be felt for a few days after the procedure.
Q. Why is the 4cc or more option separate?
Since the forehead area is a large area, there are frequent cases where a volume of 4cc or more is needed for full coverage.
It is a line frequently considered by those who want to refine the entire wide forehead because it is an option that lowers the burden per cc when performing such large-area procedures.
The forehead is an area that occupies a large portion of the upper face and affects both the front and side profile impressions.
Depending on the shape of the sunken center, M-shaped, or flat forehead, the location and direction to fill the volume change, so shape diagnosis is the background that greatly influences the naturalness of the results.
Hongdae forehead filler is a filler procedure that restores natural curves and round volume by gently placing hyaluronic acid with a cannula according to the forehead shape type.
At the Hongdae branch, in addition to forehead filler, we also operate various filler procedures under the design filler category.
It is a category that includes design filler to create a three-dimensional facial impression by filling the front cheeks, nose and temple filler to refine the bridge of the nose and temples together, and neck wrinkle filler to smoothly fill horizontal wrinkles on the neck.
In cases where there are unsatisfactory filler results, we also operate a post-management option to return to the original state with a filler dissolving line, so you can receive suggestions on the direction from pre-treatment to post-management from the perspective of overall facial balance.
The direction that fits your forehead shape and the overall balance of your facial impression will be checked directly during the consultation.

성분은 같은 히알루론산이지만 감촉과 유지 기간에서 차이가 있는 카테고리예요.
부담 없는 접근이라면 국산 라인, 안정적 볼륨감이면 국산 프리미엄 뉴라미스,
부드러운 융화 감촉이면 수입 벨로테로, 점성 응집력이면 수입 쥬비덤이 검토되는 편입니다.
Q. 이마 필러 결과는 언제 확인할 수 있나요?
시술 직후부터 이마 볼륨이 채워진 라인을 확인할 수 있어요.
