Hongdae Calf Botox: Slim down muscular calves with prominent calf muscles

June 16, 2026

Hello.

I am Dr. Kim Dong-young, Director of Cleor Clinic Hongdae Branch.

Have you ever felt that even after dieting, your calves remain thick,

and that they actually feel harder when you exercise?

"Even if I lose weight, my calves stay the same.

I'm self-conscious about the lines in my skirts or slacks, and they seem to get thicker the more I exercise."

The calf is an area where the gastrocnemius (the two-headed muscle on the outside) and the soleus (the deep muscle on the inside) are located together.

In particular, the gastrocnemius is a muscle that acts strongly in movements such as ankle movement, climbing stairs, and standing on tiptoes.

If repetitive stimulation accumulates due to high heels, ballet, hiking, or working while standing for long periods,

the muscle itself thickens, creating an environment where the calf muscle becomes prominent.

Just as giving a rest signal to tense muscles,

Hongdae calf Botox is a method that induces the volume to naturally decrease

by reducing the contraction signal of the gastrocnemius for a certain period.

Today, I will summarize what Hongdae calf Botox is,

and how the 5-type lineup, from domestic to German and US imported toxins, differs.

What is Hongdae calf Botox?

👉 Hongdae calf Botox is a procedure that injects botulinum toxin type A into the calf gastrocnemius to block the secretion of acetylcholine at the nerve endings,

thereby reducing muscle contraction signals and making the volume of the calf muscle gradually smaller.

Botulinum toxin has a mechanism of action that temporarily blocks the secretion of acetylcholine,

which transmits contraction signals to muscles at the site where nerves and muscles meet.

When the signal is reduced, the frequency of strong muscle contraction decreases,

and it is known that muscles that have been used less for a certain period gradually decrease in volume.

It is not a procedure that removes the muscle itself,

but a method of "adjusting the signal so it doesn't work too hard for a while,"

so it is a reversible procedure where the effect gradually disappears after a certain period

and the volume recovers again.

Technical features of Hongdae calf Botox

👉 Hongdae calf Botox is a procedure with three key features: botulinum toxin type A action, gastrocnemius target injection, and indication for muscular calves.

Botulinum toxin type A action

Muscles contract only when acetylcholine is secreted at the nerve endings,

  • and botulinum toxin type A temporarily blocks this secretion process.

The effect begins about 2 to 4 days after the procedure,

the greatest change is reported at 2 to 4 weeks,

and it generally lasts for about 4 to 6 months.

Gastrocnemius target injection

The calf is composed of the superficial gastrocnemius and the deep soleus,

  • and the volume of the calf muscle is mainly created by the gastrocnemius.

Calf Botox is injected precisely into the inner and outer heads of the gastrocnemius,

so the injection position is adjusted according to the muscle distribution.

Indication for muscular calves

Calf Botox is a procedure applied to muscular calves.

  • The effect is limited for fatty calves, so other options like contour injections are recommended,

and if both muscular and fatty types are present, it is common to proceed with both procedures in stages.

Whether your calves are muscular or fatty

is confirmed through the hardness and changes of the calf muscle when lying down and in a tiptoe position.

Effects and advantages of Hongdae calf Botox

👉 The key advantages of Hongdae calf Botox are summarized into three: non-surgical volume reduction, gradual and natural changes, and abundant toxin options.

First, it approaches volume reduction non-surgically.

It is not a method with a high burden of incision or post-procedure recovery,

and it is known that daily life can be resumed quickly as it is performed by micro-injection.

Next, gradual and natural changes take place.

Because it is a mechanism where the volume slowly decreases as the muscle usage is reduced for a certain period,

it is a direction that achieves natural line refinement rather than sudden changes.

Finally, there are abundant toxin options.

With a 5-type lineup including domestic, US FDA-approved domestic, domestic pure toxin, German imported pure toxin,

and US original imported toxin, it is a structure that allows you to choose according to your needs and schedule.

Hongdae calf Botox lineup

👉 At the Hongdae branch, we operate calf Botox with 5 types of toxins × 100 units and 200 units options, from domestic to imported.

100 units and 200 units are selected according to volume and muscle size.

100 units are recommended for light muscle distribution, and 200 units are recommended for thick muscular types or large distribution on both sides,

and the option that suits your calf thickness, schedule, and budget along with the type of toxin

is examined together during the preliminary consultation.

Hongdae calf Botox is suitable for those who:

Have prominent calf muscles even after reducing exercise

Have thickened muscles due to high heels, ballet, hiking, or standing work environments

Are concerned about the lines of skirts or slacks

  • Have muscular calves that do not lose weight even with dieting

  • Want to refine their lines non-surgically without the burden of incision surgery

  • Side effects and things to know in advance about Hongdae calf Botox

  • 👉 Hongdae calf Botox is a procedure with reversible effects, so it gradually recovers after being maintained for about 4 to 6 months, requiring additional procedures.

  • Immediately after the procedure, light stinging, fine bruising, and temporary muscle fatigue may accompany the treated area.

Most are reported to subside within a few days,

and daily activities are generally possible from the day of the procedure.

At 2 to 3 weeks after the procedure when the effect begins,

muscles may feel temporarily weak when climbing stairs or standing on tiptoes.

It is recommended to refrain from full-scale exercise (gym, running, hiking, etc.) for about a week.

For fatty calves, the range of change with Botox alone is limited,

so checking your calf type in advance during the consultation helps with satisfaction.

Please inform us in advance as the procedure may be restricted in the following cases:

If you are pregnant or breastfeeding

If there is active inflammation or infection at the treatment site

If you have a history of allergies or hypersensitivity to botulinum toxin ingredients

  • If you have been diagnosed with neuromuscular diseases such as myasthenia gravis

  • If you are taking medications that affect toxin action, such as antibiotics (aminoglycoside class)

  • ⚠️ Precautions before and after Hongdae calf Botox procedure

  • 👉 For Hongdae calf Botox, management by time before and after the procedure affects the stability and recovery of the effect.

  • ❓ Frequently Asked Questions (FAQ)

Q. When does the effect of Hongdae calf Botox appear?

The effect begins about 2 to 4 days after the procedure,

and the greatest change is reported at 2 to 4 weeks.

It takes about 1 to 3 months for the volume itself to settle,

and it is known to be maintained for about 4 to 6 months thereafter.

Q. How are the 5 types of Hongdae calf Botox toxins different?

The domestic line is the most commonly operated line,

and the domestic premium is a domestic product approved by the US FDA,

so it is an option that also carries overseas safety certification.

The domestic pure toxin is a domestic pure toxin with complex proteins removed,

German Xeomin is a pure toxin with 150kDa complex proteins removed,

a line known to have a relatively low possibility of resistance,

and US Allergan is a line that contains 900kDa complex proteins and has accumulated long-term clinical data.

Q. How should I choose between 100 units and 200 units of Hongdae calf Botox?

100 units are recommended if the muscle distribution is light or the calf thickness is small,

and 200 units are recommended if the muscle is thick or the distribution on both sides is large and you want a greater range of change.

The units that fit your calf thickness are determined together during the preliminary consultation.

Q. Is Hongdae calf Botox permanent?

It is a reversible procedure, so the effect gradually disappears and the volume recovers after a certain period.

It is recommended to have additional procedures after an average of 4 to 6 months,

and it is reported that the more you proceed periodically, the more the range of change maintenance settles.

Q. How much pain is there with Hongdae calf Botox?

It is reported as a level where you feel a stinging sensation because it is a micro-injection method.

Applying numbing cream is common,

and it is a procedure that is not very burdensome as the procedure time is relatively short.

Q. When can I exercise after receiving Hongdae calf Botox?

Light daily walking is possible from the day of the procedure.

However, it is recommended to refrain from intense exercise (running, gym, hiking, etc.) for about a week after the procedure

and resume gradually.

Q. Can I receive Botox for other areas after the Hongdae calf Botox procedure?

If the areas are different and the cumulative dosage is within the safe range, there are cases where they are done together.

However, since the possibility of resistance is reported if repeated procedures are performed on the same area in a short period,

the schedule and area combination are examined together during the preliminary consultation.

Calf muscles are often the result of accumulated repetitive stimulation of the gastrocnemius.

Even if you reduce exercise, once the muscle is established, it does not easily decrease,

so there is a limit where changes are felt weakly with weight loss or massage alone.

Hongdae calf Botox injects botulinum toxin type A into the gastrocnemius

to reduce muscle contraction signals for a certain period so that the volume

is induced to gradually decrease.

With 5 types of toxin lines including domestic, US FDA-approved domestic, domestic pure toxin, German Xeomin, and US Allergan,

it is a structure that allows you to choose according to your needs.

The toxin and unit composition suitable for your calf thickness and calf type

will be confirmed directly during the consultation.
