Thinking About Getting Forehead Filler? What Should I Know First? image 1

I was thinking about getting forehead filler,

but what should I know first?

Hello.

I’m Wi Young-jin from Beauty’s Doctor.

When you briefly look at your side profile in the mirror,

you may have noticed that your forehead looks slightly sunken

or flat.

When you search for “How will my forehead change if I get filler?”,

there can be so much information that it becomes difficult

to organize it all.

You may see posts emphasizing immediate results,

posts focused on side effects, and posts saying,

“Never get it all done in one session.”

To briefly state the conclusion first, forehead filler

is not just one type of procedure.

The term “forehead filler” includes two major categories,

and recovery can also vary depending on the area

and the product used.

Knowing these two things before your first consultation

can greatly reduce the time you spend feeling lost.

Where exactly is forehead filler injected, and what is used?

Forehead filler is a procedure that uses an injectable product

to fill areas beneath the forehead skin that appear hollow.

*Filler: An injectable product used to create volume beneath the skin

or stimulate collagen production.

It is often used not only in the center of the forehead,

but also to reinforce the sides and the temples.

If one side looks deeply sunken in your side profile,

the shadow can appear more pronounced even from the front.

The injection is usually performed directly above the bone

or beneath the muscle layer.

In most cases, the product is injected into the layer directly above the bone,

but depending on the area and product, it may also be divided

and injected into shallower layers.

Because the location and amount should vary from person to person,

it is important to discuss what design is appropriate for you,

rather than focusing only on “how many cc.”

What is the difference between hyaluronic acid filler and collagen boosters?

The products used on the forehead can be broadly divided

into two categories.

Hyaluronic acid filler (HA)

A change in volume may be observed immediately after the procedure.

Under the physician’s judgment,

the use of a dissolving enzyme may be considered.

It is generally known to maintain its volume for approximately 12–18 months,

although this may last longer or shorter depending on the area and product.

Collagen boosters work by stimulating collagen production

within the skin, as their name suggests.

Rather than creating a noticeable sense of volume immediately after the procedure,

the contours gradually take shape over several weeks to several months.

The two categories are not substitutes for one another.

The product selection and application method

may vary depending on the individual’s condition.

The combination to use is determined by the shape of your forehead

and the condition of your skin.

Recovery after the procedure varies from person to person

There may be slight swelling and a heavy sensation when pressed

immediately after the procedure, and some people may develop

small bruises.

Because blood vessels run relatively close to the surface in the forehead,

bruising may be slightly more visible than in other areas.

However, the first week is the period when the treated area settles,

so you may receive post-procedure care instructions.

ㅇ On the day of the procedure,

avoid saunas, heated rooms, and strenuous exercise.

Heat can increase swelling.

ㅇ Try to sleep on your back as much as possible

so that the area is not pressed from the side.

If one side is pressed during the first few days,

post-procedure care instructions may vary

depending on the physician’s guidance.

ㅇ Avoid frequently touching or massaging your forehead.

Only follow self-massage instructions if recommended by your physician.

ㅇ It is safer to reduce alcohol consumption for several days.

It may make bruising darker.

ㅇ You may gently wash your hair from the evening of the procedure,

but for the first 24 hours, keep it brief and use lukewarm water.

Avoid maintaining a bent-forward position for a long time

for several days.

Things to be sure to ask during your consultation

There are three questions that are especially helpful

during a forehead filler consultation.

First, which lines or contours of your forehead appear lacking,

and what direction the design will take as a result.

If the conversation starts simply with “how much volume,”

ask again for more details.

Second, whether hyaluronic acid filler or a collagen booster

would be more suitable, or how they might be combined.

Whether the physician can naturally explain

the different roles of the two categories is one useful sign.

Third, whether everything will be filled in one session

or divided over two or three sessions.

Because the forehead is close to the muscles used for facial expressions,

adding a large amount at once can look unnatural.

This article is a summary of general information.

For safety, the actual procedure design and product selection

should be decided in consultation with a physician

who has directly examined the shape of your forehead

and the condition of your skin.

Frequently asked questions

Q. Can it be reversed if I don’t like the result?

A. Hyaluronic acid filler can be partially dissolved

with a dissolving enzyme.

Because collagen boosters are naturally absorbed over time,

it is generally recommended to establish a step-by-step correction plan

with your physician.

Q. I bruise easily. Is it okay for me to have the procedure?

A. You can, but reducing alcohol consumption and medications or supplements

with anticoagulant effects several days before the procedure

may lower the risk of bruising.

If you take any medications regularly,

please inform the physician in advance during your consultation.

Thank you for reading this long post.
