Gastrocnemius, Read By Hand

Calf Botox in Cheongdam, Gangnam, Seoul

The outward curve of a lower leg is muscle, fat and skeleton in a proportion no mirror separates. Only the muscle share answers to an injection, and it is listed on the 100-unit body line from ₩150,000.

The Anatomy

Which calf muscle makes the curve you can see

The back of the lower leg is built in two storeys. On top sits the gastrocnemius, a two-headed muscle whose inner and outer bellies produce the rounded shape visible from behind. Underneath it lies the soleus, a flat, deep, endurance muscle that holds you upright and carries you through every ordinary step. Aesthetic dosing is addressed to the superficial storey. The deep one is left to get on with its job.

The two heads rarely contribute equally. In most legs the inner head is the larger and sits higher, which is why a calf that reads as bulky from the front is usually being widened by a single belly on the inside of the leg. From behind, the same leg can look perfectly balanced. Your director looks at the leg from three directions before deciding anything, because the shape complaint and the muscle causing it are often on different sides of the limb.

Botulinum toxin type A reduces the signal arriving at the fibres it is placed among, so those fibres contract with less force and the belly is used more gently. Over the following weeks the shape of that belly softens and the outward curve of the leg eases. Nothing is removed, dissolved or drained; the leg still has everything it walked in with. The trapezius side of the same published line, with the judgement calls that belong to a shoulder, is covered on the body botox page.

What Is Actually Wide

Three things widen a lower leg and only one of them is injectable

The test takes about a minute and it happens before any figure is quoted, because the answer decides whether there is a treatment here at all.

COMPONENT 01

The muscle belly that hardens on tiptoe

Stand and rise onto the ball of the foot. A belly that lifts, narrows and turns firm under the hand is contractile tissue, and it is the share an injection can reach. Your director marks where that firmness begins and ends, because the edges are the boundary of the map.

COMPONENT 02

The layer that stays soft under the fingers

Whatever can be lifted between finger and thumb while the leg is relaxed, and stays soft while it is tensed, is not muscle. Toxin does nothing to it. Where this layer is carrying most of the width, an injection will underdeliver and the reading points to a body contouring conversation instead.

COMPONENT 03

Bone width, ankle taper and how you walk

A short lower leg, a thick ankle or a wide shin bone changes the silhouette without any soft tissue being involved. So does habit: years of heels, dance training, hill running or a toe-heavy gait recruit the superficial storey constantly. Habit can be worked with. Skeleton cannot.

The legs are assessed one at a time. A dominant side, a previous ankle injury or a sport played on one leg regularly leaves a real difference between them, and mirroring one map onto the other limb is how that difference gets preserved instead of corrected.

The Functional Question

What a treated calf has to keep doing while the dose settles

A calf is not a cosmetic muscle taking the occasional day off. It pushes you off the floor at every step, absorbs the landing on stairs, and does more of both when you run, jump or wear a heel. That is the reason a first calf plan here is written conservatively and reviewed, instead of being written at the strongest total the line allows.

If you compete, the timing conversation matters more than the dosing one. A season, a race date or an audition sets when a first calf plan should start, and sometimes the answer is that this is not the month for it. Comfort measures during the session are confirmed with you at the consultation.

Reading The Result

How to judge a calf result without reaching for a tape measure

Nothing at all changes on the day of the injection, and very little changes in the first week
The change is gradual, arrives over weeks, and continues while the belly is being used more gently
Judge it from standing photographs taken from behind and from the front, in the same light and the same footwear
A centimetre figure is a promise nobody can make honestly before an examination, so this clinic does not publish one
Silhouette matters more than circumference: how the curve runs from knee to ankle is what reads in a photograph

The review appointment is where a calf plan is actually finished. Your director compares the standing captures, checks whether one leg has responded ahead of the other, and decides whether the map extends. Results vary between individuals with muscle bulk, training load and metabolism, and a first plan here is deliberately written with room to add. With the clinic open 365 days a year, a review can sit on a Sunday if that is what your week allows.

Who Is Turned Away

When a calf consultation ends without an injection

The most frequent refusal has nothing to do with safety. It is a leg whose width is carried by the soft layer or by the skeleton, where the belly barely hardens on tiptoe and the hand finds almost nothing contractile to treat. We do not recommend a calf dose on that reading, and you are shown what the examination found before any money is discussed. A second refusal is timing: an athlete mid-season, or anyone whose next eight weeks depend on the leg performing at its maximum, is better served by starting later.

Treatment is declined outright during pregnancy and breastfeeding, where a neuromuscular condition appears in your history, and where there is infection, inflamed skin or an open wound inside the field to be mapped. Mention blood-thinning medication or supplements, any previous reaction to a toxin, and any medication affecting neuromuscular transmission, because each of those changes what can be offered.

The risks are worth naming plainly. Bruising and swelling at the entry points, tenderness for a day or two, and a dull ache in the muscle are the ordinary ones. Asymmetry while one leg responds ahead of the other is the thing a review most often corrects. A total that runs high for a particular leg can leave the calf feeling weak or easily fatigued during demanding effort, which is temporary and is the exact reason the first plan is written low. Pain that climbs instead of fading, or a leg that feels genuinely unreliable underneath you, is a same-day phone call.

Listed Rates

What a 100-unit session is listed at for calves in Cheongdam

Calves are quoted on the published body line, which is sold in sessions of 100 units. The Korean tier is ₩150,000 (≈ $105) and the imported tier is ₩650,000 (≈ $465). How many of those sessions a pair of legs calls for is decided at the examination and approved by you before anything is drawn, and the tier is your choice.
TierWhat the listed body session coversPer 100 units
KoreanA domestically manufactured botulinum toxin type A, mapped across the superficial calf bellies with each leg planned separately₩150,000 (≈ $105)
ImportedAn imported premium-tier type A product, same mapping and the same sitting, for patients who prefer it₩650,000 (≈ $465)

Korean pharmaceutical advertising rules keep prescription toxin product names off public pages, so the table shows tiers and not manufacturers; your director names the product in the room and shows you the vial before it is opened. A body muscle takes a far larger unit load than any facial one, which is why this line is published per 100 units instead of per area. Rates are identical for residents and visitors, and the KRW figure is what you pay. The rest of the clinic sits on the published price list, with the toxin ladder explained on the botox price page and the soft-tissue alternatives on the body contouring page.

Dear, Knowhow

How a lower leg is examined before a calf total is written at Dear

01 — THE FULL ARSENAL

Saying your calf is soft tissue costs us nothing

Body contouring devices and the injectables share this building, so a leg whose width is not contractile can be sent to the category that actually addresses it.

02 — DIAGNOSIS FIRST

EVE Muse 3D + AI sets the habit the leg is measured with

The clinic's EVE Muse 3D imaging with five-light-source AI analysis is a face instrument, and what it establishes here is the discipline: measure, write it down, compare it at review. On a calf that takes a physical form, with each leg palpated relaxed and on tiptoe, photographed standing from three angles, and the findings recorded so the next visit begins from evidence.

03 — DIRECTOR-PERFORMED

Each leg marked standing, by a director

The bellies sit where they sit under load, so the marks go on while you are standing on the leg. One leg is mapped, then the other, and the session is director-performed from the first point to the last. The totals between the two legs usually differ.

FAQ

Calf toxin, question by question

How do I know whether my calf is muscular?
Rise onto the ball of one foot and put a hand on the back of the leg. If a defined belly lifts and turns hard, that is contractile tissue and it is the part an injection reaches. If what you feel stays soft and can be lifted between two fingers even while you are on tiptoe, the width is being carried by something toxin does not act on. Your director checks both legs this way before quoting anything.
How much is a calf session here?
Calves are quoted on the published body line in 100-unit sessions: ₩150,000 (≈ $105) on the Korean tier and ₩650,000 (≈ $465) on the imported tier. How many sessions a pair of legs needs comes out of the examination, and the total is approved by you before the vial is opened. Visitors and residents pay the same published figure.
How many centimetres will my calf lose?
No responsible figure can be given before a leg has been examined, and this clinic does not print one. What changes is the shape of the superficial bellies as they are used with less force, and how visible that is depends on how much of your width was muscle to begin with. Standing photographs from the same angle are a fairer measure than a tape, which moves with the height it is held at.
Will my legs feel weak when I walk?
Ordinary walking, standing and stairs are what the plan is built to leave alone, because the deep endurance muscle underneath is not the target and the totals are kept conservative. Where a difference does show up it is usually in explosive effort — sprinting, jumping, rope skipping — and it is temporary. Tell your director if that kind of work is part of your week.
I run and train seriously. Should I have this done?
Possibly, but the timing conversation comes first. A leg in a training block or a season has to keep performing, and a calf plan is better placed in an off period. Say what you train, how often, and what the next eight weeks contain, because that changes both the map and whether we start at all.
When will I see a change, and how long does it last?
Nothing shows on the day and very little in the first week. The softening arrives over the weeks that follow and continues while the belly is being used more gently. How long it holds moves with muscle bulk, training load and your own metabolism, so your director gives you the expected pattern for your legs at the consultation instead of a fixed number.
Does it hurt, and can I walk out normally?
The injections are quick and most people describe a dull pressure in the muscle. You walk out on your own legs and carry on with your day. What we ask is that you skip heavy leg training, deep massage of the calf, saunas and alcohol for a few days while the dose settles. Comfort measures are confirmed at the consultation.
Do both legs have to be treated?
Where the aim is shape, normally yes. Treating one leg and leaving the other means walking on two calves with different force behind them, which is not a comfortable arrangement. The two legs are mapped and dosed separately though, because almost nobody is symmetrical and the dominant side usually carries more.
My calf looks bulky because I wore heels for years. Does that change anything?
It explains the muscle share rather than ruling it out. A calf held short in heels does more work than a flat-shoe calf, and the superficial bellies respond to that. What is worth knowing is that the first week back in flat shoes can feel unfamiliar as the leg adjusts, and that this settles.
Can I have my calves and my shoulders treated on the same visit?
Often yes. Each area is quoted in its own 100-unit sessions, so a visit covering both is quoted as separate lines you approve individually. Whether it is sensible on one day depends on the combined total and on what your week looks like afterwards, and your director settles that with you before booking.
Who should not have calf treatment?
Anyone pregnant or breastfeeding, anyone with a neuromuscular condition in their history, and anyone with infection, inflamed skin or an open wound inside the field. Blood thinners and supplements that thin blood need mentioning because of bruising. And where the examination finds the width is soft tissue or skeleton, we do not recommend the injection, whatever you came in hoping to hear.
I am visiting Seoul briefly. Can it be done the day I come in, and how do I book?
Usually yes — the examination, the consultation and the session fit inside one appointment once you have approved the figure, and Dear Clinic is open 365 days a year including Sundays and public holidays. Since the change arrives over weeks, a calf plan works perfectly well on a short trip: you fly home and the result develops there. Send the form below with your dates and what you train, and we reply in English as soon as possible.

Scientific Evidence

Published sources behind unit-based toxin dosing

Three references cover botulinum toxin type A as a clinical tool: the first published account of treating expression lines with it, an international consensus education initiative on its aesthetic application, and a laboratory review of how the licensed type A products differ in formulation and in the units they are measured in.

The last of those is the reason units are never interchangeable between products, and the reason a plan is written in units for a named tier. None of the three describes your legs or sets a total for them; that comes from the examination at your own appointment.
