Hello.

I’m Ha-won Kim from Beauty's Doctor.

Have you ever gently lifted your forehead or the area above your eyebrows with your hand while looking in the mirror?

Some people look into forehead lifting because the area around their eyes appears slightly less heavy or their eyebrow line seems more defined when they do this.

However, the reason the forehead may look heavy cannot be explained by reduced skin elasticity alone.

The thickness of the forehead skin, the position of the eyebrows,

The condition of the eyelids and habitual patterns of muscle use may also have an influence.

Therefore, rather than choosing a specific procedure first,

it is necessary to first examine why the forehead and eye area currently appear to sag.

Today, I’ll summarize the main methods of forehead lifting,

the realistic range of results that can be expected,

and what to check after the procedure.

Three-line summary

  1. Forehead lifting can be divided into several methods, including ultrasound, radiofrequency, and threads.

  2. The appropriate approach may vary depending on skin thickness, eyebrow position, and the cause of the sagging.

  3. If severe pain develops after the procedure, or reduced sensation and asymmetrical movement appear, have your condition checked by a medical institution.

1) First, examine why the forehead appears to sag

Just because the forehead looks heavier than it used to

does not mean that everyone has the same underlying cause.

As skin elasticity decreases,

the tissue above the eyebrows may appear to descend,

and repeatedly using the forehead muscles to open the eyelids

can also deepen horizontal lines.

If the natural eyebrow height differs from side to side

or one side’s muscles are used more frequently,

the feeling of heaviness around the eyes may also differ.

If these differences are not assessed

and only strong stimulation is applied,

the treatment area may not align with the desired outcome.

During a consultation, it is helpful to examine not only the forehead skin

but also the eyebrow position and eyelid movement,

as well as how the muscles are used

when making facial expressions.

2) How do the different forehead lifting methods compare?

Forehead lifting can broadly be divided into methods that use

ultrasound or radiofrequency,

and methods that insert threads.

Ultrasound methods

deliver energy by concentrating it at a set depth.

The depth and intensity used

are adjusted according to skin thickness and the treatment area.

Radiofrequency methods

deliver thermal energy to the skin tissue

to help manage elasticity.

Depending on the device,

the range over which energy is delivered

and the way the skin is heated can differ,

so not all radiofrequency treatments are the same.

Thread lifting

involves inserting threads beneath the skin

to physically reposition sagging tissue.

The direction of the lift

can be determined relatively specifically,

but swelling and bruising,

as well as tightness or a sensation of something foreign,

may be more noticeable.

Rather than one method always being better,

the choice depends on skin thickness, the direction of sagging,

and the desired extent of contour refinement.

3) What level of results is reasonable to expect?

Some people expect forehead lifting

to significantly raise the eyebrows

or completely change the appearance of their eyes.

In reality, however,

rather than dramatically changing the overall impression of the face,

it is closer to reducing a heavy appearance

and naturally refining the forehead and eyebrow lines.

Even when the same method is used,

responses may differ depending on skin thickness and elasticity,

eyebrow position, and habitual patterns of muscle use.

The tightness felt immediately after the procedure

may also differ from the settled appearance after some time has passed.

If sagging of the eyelids themselves

or problems related to the function of opening the eyes

are the main cause,

forehead lifting alone

may not achieve the expected range of improvement.

Rather than using the appearance shown in reviews

as your standard,

it is better to decide after hearing

how much refinement is possible for your own condition.

4) What should you check after the procedure?

Immediately after the procedure, redness and swelling,

as well as tingling or mild tenderness, may occur.

After thread lifting, you may also feel tightness when making facial expressions

or notice temporary skin irregularities.

These reactions

generally lessen gradually,

but the severity and recovery period may vary from person to person.

At first, reduce activities that increase heat,

such as saunas and strenuous exercise,

and avoid pressing firmly on the treated area

or receiving vigorous massages.

The timing for resuming washing your face, applying makeup,

and exercising

may vary depending on the method used,

so follow the instructions provided after the procedure.

If the pain becomes more severe over time

or a feeling of reduced sensation continues,

if sudden asymmetry appears when moving the eyebrows,

or if severe swelling and changes in skin color occur

and you notice a reaction different from usual,

rather than dismissing it based on your own judgment,

have your condition checked by the medical institution where you received the procedure.

In closing

Forehead lifting

is not simply a procedure that pulls the area as strongly as possible.

It is closer to a process of examining the condition around the forehead and eyebrows

and refining the contours in a way that suits the current face.

Ultrasound, radiofrequency, and thread lifting

differ in their mechanisms and recovery processes.

Rather than choosing a specific method first,

first check the thickness of the forehead skin, the eyebrow position,

and habitual patterns of muscle use.

It is important to make a plan

after fully understanding the expected range of refinement and recovery process,

as well as the reactions that require caution.

Frequently asked questions

Q. Is one forehead lifting treatment enough?

The number of treatments needed varies depending on the method used

and the current condition of the skin.

Rather than deciding on the total number of treatments from the start,

it is better to observe the skin’s response after the initial treatment

and how the contours settle over time.

Q. Which is better, ultrasound or radiofrequency?

The two methods may differ in how they deliver energy

and in the depths at which they are applied.

Since the choice varies depending on skin thickness and elasticity

and the desired treatment area,

it is difficult to say that one method is always better.

Q. Does thread lifting create an immediate pulling sensation?

Because the tissue is repositioned with threads,

you may feel tightness at first.

However, swelling or skin irregularities may also appear,

so you should allow some time and observe the changes

rather than judging by the appearance immediately after the procedure.

Q. When should I contact a medical institution after the procedure?

If the pain continues to worsen

or reduced sensation and asymmetrical movement occur,

or if severe swelling or changes in skin color appear,

it is necessary to have your condition checked.

Rather than simply waiting,

contact the medical institution where you received the procedure.
