Forehead filler is a key to a youthful appearance,

but ‘safety’ comes first.

Hello.

This is Kim Hawon from Beauty's Doctors.

One of the key conditions for looking youthful is

a smooth forehead with just the right amount of volume.

However, the forehead has a wide area and thin skin,

so when it comes to filler procedures,

naturalness and safety are especially important.

Today, for those considering forehead filler,

I will organize only the essential information from a doctor’s perspective:

🍑 proper dosage 🍑 how long it lasts 🍑 criteria for choosing a clinic that avoids mistakes

  1. Why is anatomical understanding

the top priority for forehead filler?

Many people think of fillers as simply a procedure that fills empty space,

but the forehead is medically a very difficult area.

That is because under the forehead skin,

the supraorbital nerve,

the trochlear nerve,

and a complex connected vascular structure run through it like a net.

Choosing the precise layer is important.

Forehead filler should be injected not just under the skin, but into the layer directly above the periosteum.

If the layer is chosen incorrectly,

🍑 the filler may move with muscle movement, or 🍑 uneven contours may appear when making facial expressions

which can cause problems.

Using a cannula is a rule, not an option.

I use a cannula with a blunt tip instead of a sharp needle.

This

🍑 significantly lowers the risk of vascular damage, and 🍑 is chosen to minimize bruising and swelling, 🍑 which are the main concerns after the procedure.

  1. “How many cc do I need?”

Why personalized design is necessary

One of the questions I get most often in the consultation room is about dosage.

But there is no fixed answer to this question.

That is because every patient has different

🍑 forehead width 🍑 degree of brow bone protrusion 🍑 skin elasticity and thickness

.

Average dosage guide

🍑 Overall forehead volume improvement: 3 cc to 5 cc 🍑 If only the central hollow area needs correction: 1 cc to 2 cc

Depending on the condition,

a small amount can still produce satisfying results.

You must remember that too much of a good thing is too much.

Excessive pursuit of volume can create an unnatural look, like the so-called ‘goldfish forehead.’

I design the angle of the S-line that connects the glabella and the nose line,

so that a natural three-dimensional effect is felt from both

🍑 the side profile 🍑 the front view

.

  1. The procedure, pain, and the art of ‘molding’

Forehead filler procedures, including anesthesia, are carried out in about 20 to 30 minutes.

To reduce pain,

🍑 nerve block anesthesia 🍑 local anesthesia

are used together,

and the pain actually felt by patients is usually not as great as expected.

The key step that makes a difference in the result: molding

The step I put the most effort into during the procedure is the ‘molding’ done immediately after injection.

This is the process of carefully shaping the filler by hand so that it settles smoothly according to the forehead curve,

and in this step, the doctor’s

🍑 aesthetic sense 🍑 experience and know-how

make the difference between results.

  1. Doctor-provided post-procedure care

Please be sure to follow this

If the procedure is done well, this is now the time when the patient’s care matters.

It takes about two weeks of care for the filler to settle stably between the tissues.

Avoid physical pressure.

🍑 Wearing a hat tightly 🍑 Glasses or sunglasses pressing continuously on the forehead 🍑 The habit of sleeping face down

can all cause the filler shape to change.

Limit environments with high heat.

🍑 Sauna 🍑 Jjimjilbang 🍑 Intense exercise

can increase blood flow,

cause swelling, and speed up filler metabolism,

so it is best to avoid them for 1 to 2 weeks.

No drinking and no smoking are musts.

Alcohol and cigarettes can trigger inflammatory responses in the body, so for stable recovery, I strongly recommend avoiding them.

  1. Side effects and precautions

As a medical professional, I have a duty to explain not only the benefits of the procedure

but also the possible risks transparently.

All filler procedures may cause, depending on the individual,

🍑 inflammation 🍑 asymmetry 🍑 temporary pain and swelling

.

In particular, although very rare, if the filler compresses a blood vessel or enters the vessel,

🍑 skin necrosis 🍑 reduced vision

and other serious side effects are also possible.

Therefore, after the procedure, if

🍑 the pain gradually worsens 🍑 the skin becomes excessively red 🍑 the skin color turns pale

please do not delay and contact the medical institution where you received the procedure immediately and receive medical care.

Forehead filler

has now become a popular procedure, but it is by no means a light one.

Rather than low cost or sensational advertising,

🍑 accurately understanding facial anatomy 🍑 choosing medical staff who provide sufficient explanation and responsible care

is the most important criterion for a satisfying result.

If you are worried about your forehead line, please feel free to ask anytime.

For the most harmonious and least burdensome beauty for your face, I will always do my best.

Thank you for reading.
