Botox is a treatment that uses botulinum toxin

to temporarily regulate muscle movement or nerve transmission.

It works by reducing signal transmission between the nerves and muscles,

thereby temporarily reducing muscle movement.

Depending on the purpose and treatment area, it may be used with the expectation of improving wrinkles or reducing muscle movement.

It can also affect

nerve transmission related to the sweat glands,

so it is also used to treat hyperhidrosis.

Eyebrow-lifting Botox regulates movement of the muscles around the eyebrows,

which may result in changes to the eyebrow line.

Lip flip Botox regulates movement of the muscles around the lips,

which may result in changes to the upper-lip line,

and results may vary from person to person.

When do Botox results start to appear?

Botox results usually begin to appear gradually 2–7 days after treatment.

Changes begin as muscle movement gradually decreases,

and many people experience the greatest effect at around 2–4 weeks.

How long do Botox results last?

Although there are individual differences,

results commonly last about 3–6 months,

with variations depending on the condition of the muscles and the treatment area.

However, the duration may vary depending on the amount of muscle use, lifestyle,

amount of exercise, and treatment area.

Changes in duration after repeated treatments

may vary from person to person.

When can you exercise, use a sauna, or drink alcohol after Botox?

It is best to avoid strenuous exercise, alcohol, and saunas on the day of treatment.

This is because increased body temperature and blood flow

may worsen swelling, bruising, and discomfort.

The time it takes to return to daily activities may vary from person to person,

so it is best to follow your healthcare provider’s instructions.

After square jaw Botox,

why might the jaw muscles look more prominent?

Immediately after treatment or several days later, the jaw muscles may temporarily

feel as though they look more prominent.

This may occur during the muscle adaptation process

and usually improves naturally.

Depending on the individual, there may also be a feeling of muscle tightness

or soreness.

After square jaw Botox,

is it normal to have difficulty opening the mouth?

As use of the chewing muscles decreases after treatment,

you may feel that it is difficult to open your mouth fully.

The movement of the jaw may also feel awkward

due to soreness or pain in the treated area.

In most cases, this naturally improves after about 3–7 days.

After square jaw Botox,

should tough foods be avoided?

After treatment, you may be advised to reduce foods that require prolonged chewing for a certain period

to reduce use of the jaw muscles.

In particular, foods that require prolonged chewing, such as squid, nuts, tough meat, and chewing gum,

may increase the amount of jaw muscle use.

After forehead and glabellar Botox,

why might the eyes feel heavy?

In rare cases, the eyes may feel heavy after forehead or glabellar Botox due to changes in eyebrow position.

Depending on the individual, you may experience a feeling that the eyebrows are raised,

or a heavy sensation in the forehead.

Symptoms of ptosis, or drooping eyelids, may also occur.

These symptoms may improve over time in some individuals,

but if they persist, it is best to consult a healthcare provider.

After trapezius or body Botox,

can a feeling of weakness occur?

Temporary weakness or soreness may occur after body Botox.

A feeling that the muscles look more prominent may also occur during the adaptation process.

These symptoms may improve over time in some individuals,

but if they persist or are severe, medical attention may be necessary.

In very rare cases, speech difficulties, difficulty swallowing, or difficulty breathing,

drooping eyelids, double vision, or reduced vision may occur.

If symptoms are severe, medical attention may be necessary.

In such cases, medical evaluation may be needed.

If the following symptoms persist severely,

medical attention may be necessary.

Severe drooping of the eyelids

Severe asymmetry

Difficulty chewing food

Pain that is progressively worsening

Difficulty breathing or swallowing
