Can Temporalis Botox Make the Temples Look Hollow? image 1

Hello.

I’m Ha-won Kim from Beauty's Doctors.

When looking into temporalis Botox,

you may come across claims that

the temples can appear sunken

or that the face may look

so-called peanut-shaped.

You may also wonder why injections are given

in the temples rather than

in the square-jaw area.

However, changes in the temples

do not appear in the same way for everyone.

The size of the muscles, facial bone structure,

injection location, and dosage

all need to be considered together.

Why is temporalis Botox

given in the temples?

The temporalis is one of the chewing muscles

located around the temples.

Along with the masseter in the square-jaw area,

it moves when you chew food or clench your teeth.

The area that becomes firm when you clench your teeth

while touching your temple is the temporalis muscle.

Some people have more developed masseter muscles,

while others also have prominent temporalis muscles.

Therefore, when examining the side profile of the face

or tension in the chewing muscles,

it is possible to assess not only the masseters

but also the size of the temporalis muscles

and differences in how each side is used.

The two areas are not always treated together,

and the plan varies depending on the current condition of the muscles.

What is the relationship with

square-jaw Botox?

The masseter and temporalis are both

muscles involved in chewing.

If you frequently clench your teeth

or have a habit of chewing only on one side,

the degree of development of the two muscles

may differ.

Receiving square-jaw Botox does not necessarily mean

that treatment of the temples is also needed.

However, if the way the masseter and temporalis are used together

or differences between the muscles on the two sides of the face

are identified, the injection areas and dosages

may be divided with balance between the two areas in mind.

Rather than deciding based only on the size of one area,

it is important to also observe how the muscles move while chewing.

Why is it also mentioned

in relation to headaches and teeth grinding?

The temporalis can become tense

when you clench your teeth

or grind them during sleep.

As a result, some people may feel tightness in the temples

or fatigue around the jaw.

This is why some people look into temporalis Botox

in relation to headaches or teeth grinding.

However, headaches can have many causes,

and not all temple pain is caused by muscle tension.

Other causes, such as temporomandibular joint problems,

the condition of the teeth, and sleep habits,

may also need to be checked.

If you are considering treatment for headache relief,

the location and frequency of the symptoms

should first be evaluated during a consultation.

What reactions may occur

after the procedure?

The injection site may feel sore

or uncomfortable when pressed.

Small bruises, red injection marks,

or mild swelling may also occur.

As the movement of the chewing muscles changes,

you may feel less strength than usual

when eating hard foods

or become tired more easily.

These reactions may vary depending on

your muscle volume and the injection area.

While the discomfort is subsiding,

it may be more comfortable to reduce

chewy foods and meals that require prolonged chewing.

Why might the temples

look hollow?

As the volume of the temporalis muscles decreases,

the contour of the temples may also change.

If your temples were already somewhat hollow

or you have little facial fat,

even a small change may be more noticeable.

A hollow appearance of the temples after temporalis Botox

may be affected not only by the injection location and dosage,

but also by the original size of the muscles

and the shape of the underlying bone structure.

If the muscle volume differs between the two sides

but the same dosage is injected,

asymmetry may appear more pronounced than before.

Therefore, rather than aiming for a major change all at once,

it is important to adjust the treatment according to the current muscle volume.

When should you

have it checked again?

If the temples look more hollow than expected

or the difference between the two sides has become pronounced,

it is advisable to have the current muscle movement checked

at the medical institution where you received the procedure.

You should also seek an evaluation if your strength has decreased

to the point that chewing is difficult

or if discomfort continues for a long time.

If the movement of your eyebrows or eyelids changes

or asymmetry appears in your facial expressions,

you should inform a medical professional of your condition

rather than waiting and judging it yourself.

What is assessed

during a consultation?

During the consultation, the degree of movement

of the masseter and temporalis is checked

when you clench your teeth.

Your usual teeth-grinding or one-sided chewing habits,

as well as any discomfort in the temporomandibular joint,

are also assessed.

The original hollowing of the temples,

the amount of facial fat,

and differences in the bone structure between the two sides

are also important.

If you have previously received Botox

in the square-jaw or temple areas,

it is helpful to provide the timing of the procedure

and your reaction at the time in advance.

Treatment of both areas is not necessary for everyone.

After an examination, it is necessary to assess the current condition of the muscles and your goals,

then determine the injection areas and dosage.

Frequently asked questions

Q. Do I have to receive temporalis Botox

along with square-jaw Botox?

It is not always performed together.

After assessing the degree of development of the masseter and temporalis

and your chewing habits,

the plan can be limited to the areas that need treatment.

Q. If my temples look hollow,

can they return to their previous appearance?

The effects of botulinum toxin

may gradually weaken over time.

However, the degree and timing of recovery

may vary depending on the muscle volume

and the injection status.

Q. Is it an acceptable reaction if my chewing strength decreases?

You may temporarily feel tired or uncomfortable

when chewing hard foods.

If the discomfort is severe or persists for a long time,

it is advisable to check with the medical institution

where you received the procedure.
