Hello.

I am Kim Jin-hyun, Chief Director of YOU&I Clinic Mok-dong Branch.

“ My forehead wrinkles keep bothering me.

Should I get Botox?

Or would filler be better? ”

Especially in areas closely connected to facial expressions, such as the forehead, the causes of wrinkles can vary widely, so it is very important to properly distinguish which procedure is suitable: Botox or filler.

Simply getting Botox because there are wrinkles, or insisting on filler just because the forehead looks hollow, can actually lead to unwanted results.

Today, I will explain the differences between procedures and the criteria for application that anyone interested in forehead Botox should understand.

The difference between forehead Botox and filler

Botox and filler work in completely different ways.

Botox works on the muscles to suppress excessive movement, helping to prevent and reduce wrinkles caused by repeated facial expressions.

For example, it is suitable for horizontal forehead wrinkles caused by habitual expressions such as surprise or frowning.

Filler is a procedure that injects substances such as hyaluronic acid under the skin to help fill in hollows or smooth out contours.

It is often used to create a rounded curve in deeply etched wrinkles or in areas of the forehead where volume has decreased.

In other words, it may be easier to understand Botox as a procedure that stops movement, while filler is a procedure that shapes the form.

When forehead Botox is suitable

“ Then which procedure is

suitable for my forehead right now? ”

First, if expression lines have started to appear, Botox may be suitable.

If marks start to remain on the skin due to habits such as frowning the forehead or raising the eyes, early treatment can help prevent the condition from becoming more severe.

Also, when the forehead feels tense overall and the expression appears harsh, Botox is often used to control muscle movement and create a softer impression.

However, because Botox acts on the frontalis muscle that creates expressions, if the treatment design is not precise, side effects such as an unnatural appearance or eyelid drooping may occur.

Since the forehead has a wide area and a thin skin layer, precise planning that takes into account the vertical arrangement of the muscles, forehead height, and the proportions between facial features is essential.

On the other hand, if the forehead is flat and sunken, or if the side profile looks plain,

or if the wrinkles are so deeply etched that they cannot be filled by muscle suppression alone, or if you want to correct the forehead line, filler can be considered.

Things you must know before the procedure

Botox is a relatively simple procedure, but possible side effects cannot be ignored.

This is true for any procedure.

For example, if the forehead muscles are excessively suppressed, the compensatory action of opening the eyes with the forehead is blocked, and the eyes may feel uncomfortable.

For those who already have symptoms such as eyelid drooping, adjusting the dosage and design is very important.

If too much is injected or the left and right muscles are suppressed asymmetrically, the impression may become awkward or facial expressions may look difficult to make.

Or, even if the larger movements are reduced with Botox, the fine skin tension around the area or minor muscles may stand out, so in some cases fine adjustments may be needed.

That is why forehead Botox should not be approached simply as “getting an injection,” but rather as something that requires delicate design and consultation based on an understanding of facial structure.

The forehead is one of the areas of the face that can express emotions the most.

Therefore, the key to forehead Botox is to preserve expressions while preventing wrinkles.

If you do not properly understand the structure and function of the forehead, it will be difficult to achieve a satisfying result.

If you are considering Botox for forehead wrinkles, I hope you will use today’s information to approach it carefully.

This has been Kim Jin-hyun, Chief Director of YOU&I Clinic Mok-dong Branch.

Thank you.
