About

What is body botox?

Body botox is botulinum toxin injected into a large body muscle — most often the trapezius across the top of the shoulder, or the calf — to relax how hard that muscle contracts. As the muscle works with less force, its bulk softens over the following weeks, so the shoulder line looks longer and the lower leg looks slimmer. Dosing is quoted per 100 units.

The mechanism is local. Botulinum toxin blocks the signal that tells the injected fibres to contract, so the muscle pulls with less force and its bulk softens as it is used more gently. Nothing is cut, nothing is dissolved, and no fat is removed. A thick-looking shoulder can come from an overworked trapezius, from a forward-rolled posture, from where your body stores fat — or from all three at once, in proportions no mirror will separate for you. Only the muscle share answers to an injection, so your director feels the muscle at rest and under contraction before quoting a single unit.

The trapezius holds your arm up all day and the calf carries you along the pavement. Neither is a muscle to switch off, so the dose is staged: the plan starts moderate, and it is reviewed before a single extra unit is added.

Treatment Areas

Where a body dose actually lands

Two muscles, and the two judgement calls that decide whether an injection belongs in your plan at all.

01

Trapezius & shoulder line

The sloping ridge from neck to shoulder. Relaxing an over-developed trapezius lets the shoulder line drop and flatten, and a flatter slope reads as a longer neck in photographs taken from the front.

02

Calves

A calf that bulges high and hard when you rise onto your toes is usually muscular. Softening that contraction eases the outward curve of the lower leg into a straighter line.

03

Left–right balance

Almost nobody is symmetrical. A dominant side, a bag-carrying shoulder or a sport habit can make one side thicker, so the two sides are mapped and dosed separately rather than mirrored.

04

Muscle vs fat vs posture

If the thickness is mostly soft tissue, or if a rounded posture is holding the shoulder up, an injection will underdeliver. That is checked by hand before any unit count is quoted, and what the hand finds decides the plan — sometimes a different treatment, sometimes none.

How a unit plan is built

Muscle first, dose second

A trapezius takes a far larger unit load than any facial muscle and does far more work with it, so the sequence below is built to move the line gradually and leave room to add.

STEP 01

Read the muscle

Your director palpates the trapezius or calf relaxed and then contracted, comparing both sides and noting how much of the visible bulk actually hardens under the hand. That difference is the treatable part.

STEP 02

Map the points

Injection points are marked along the muscle belly, away from the zones that do the lifting and walking work you rely on. The two sides get separate maps, because the thicker shoulder rarely wants the same one.

STEP 03

Dose conservatively

Units are quoted in 100-unit sessions and set at the low end that can realistically move your muscle. We start low and top up at the review visit.

STEP 04

Review, then refine

You come back once the effect has settled in. If one side lagged or the line needs a little more, that is topped up at review — which is why we do not front-load the dose on day one.

What Dear brings to a trapezius or calf plan

01 — THE FULL ARSENAL

Toxin is one of several body routes here

Body toxin shares this building with radiofrequency and ultrasound body systems, boosters, fillers and skin treatments. When the shoulder turns out to be soft tissue under the hand, the plan moves to one of those.

02 — DIAGNOSIS FIRST

Both sides measured before a unit is drawn

Dear’s EVE Muse 3D imaging with five-light-source AI analysis sets the diagnostic habit used across the clinic, and on the body it takes a physical form: both sides are palpated relaxed and contracted, compared against each other and written down, so the unit difference between a dominant shoulder and a quiet one rests on something your director can measure again at the review visit.

03 — DIRECTOR-PERFORMED

Each side marked on its own map

Sessions are director-performed. One shoulder is marked, then the other. The totals usually differ by a few units, and the map is kept so the next visit starts from what was actually given.

Every planDoctor consultation · muscle assessment · aftercare guidance · review visitincluded

Published rate as of September 2026. Dear carries both a Korean and a premium imported tier of botulinum toxin, and both are genuine, licensed products — the tier is a cost and preference choice discussed at consultation. You approve the unit count and the total before treatment; there are no surprise add-ons and no upselling. Every treatment price at the clinic is listed on the full price list.

Caution

After a trapezius or calf session

Small injection marks or brief tenderness at the points are normal and settle within a day or two.
Skip heavy shoulder or leg training, and deep massage of the treated muscle, for a few days.
Avoid saunas, hot baths and alcohol on the day of treatment.
The change is gradual. Judge it at your review visit; the first few days show almost nothing.
If anything feels unusually weak or uneven, contact us; aftercare follow-up is part of the treatment.

FAQ

Body botox, answered

Is trapezius botox worth it?
If the bulk you dislike hardens under your fingers when you shrug, then yes — relaxing that muscle is one of the few non-surgical ways to change a shoulder line, and the change reads clearly in photographs. If the bulk is fat or posture instead, an injection will underdeliver, and you are told so at the assessment, before you pay.
How much does body botox cost in Seoul?
At Dear Clinic a 100-unit body session is ₩150,000 (≈ $105) with a Korean botulinum toxin and ₩650,000 (≈ $465) with a premium imported one. That is the published rate for locals and international visitors alike, and your unit count is agreed at consultation before anything is injected.
How does an injection slim the shoulder line?
It does not remove anything. Botulinum toxin reduces how forcefully the injected trapezius contracts, so the muscle is used less intensely and its bulk softens over the following weeks. The visible effect is a lower, flatter shoulder slope and a neck that looks longer, and it appears gradually over weeks.
How many units will I need?
That is set by how developed the muscle is and whether one or both sides are treated, and sessions at Dear are quoted in 100-unit blocks. Your director measures and compares both sides first, starts at a conservative dose, and refines it at the review visit once the effect has settled.
When will I see a change, and how long does it last?
Nothing changes on the same day. Relaxation builds over the following weeks, and the slimming keeps developing after that as the muscle is used more gently. How long it holds varies with your muscle mass, training load and metabolism; Dear does not publish an average figure, so your director gives you a range for your own muscle at diagnosis and checks it against the review photographs.
Does it hurt, and is there downtime?
The injections are quick pinpricks into muscle, usually described as a short dull ache. Numbing cream is available. There is no recovery period — you leave and carry on with your day, avoiding a heavy gym session, deep massage of the area and a sauna for a few days.
What is the difference between the Korean and imported product?
Both tiers at Dear are genuine, licensed botulinum toxin used with the same technique and the same unit-based planning. They differ in manufacturer and price, and some patients simply prefer the imported tier they already know from home. Your director explains both at consultation and the choice stays with you.
Will my shoulders or calves get weak?
A conservative, well-placed dose reduces excess contraction while leaving the muscle working, so everyday lifting and walking should feel normal. Very heavy training in the first weeks can feel slightly different while the effect settles. Tell your director if you compete or train seriously, so the dose and the points are planned around it.
Can I treat the trapezius and calves in the same visit?
Yes, both areas can be addressed on the same day when the assessment supports it, and each area is quoted separately in its own 100-unit sessions. Whether it is sensible to do both at once depends on your total dose and your schedule, which your director reviews with you first.
Can the injection happen on the day I come in?
Usually yes. The consultation and the muscle assessment happen in the same visit, and if your doctor confirms suitability the injection can follow immediately. Dear Clinic is open 365 days a year including Sundays and holidays, so a Sunday shoulder appointment is a real one.
What if my shoulder bulk is fat rather than muscle?
Then this treatment is the wrong tool, and we will say so. Toxin acts on muscle contraction only and does nothing to fat, so injecting it would spend your money on the wrong tissue. Dear carries body contouring options for soft-tissue concerns, and the diagnosis decides which of them, if any, fits.
Is the price the same for visitors, and how do I book from abroad?
The same published rate applies to everyone — KRW is what you pay and the USD figure is shown for reference only. Send the consultation form below with your travel dates, and say whether you train or compete, because that changes where the points go and how many units are used. We reply in English within one business day and hold the slot without a deposit.

Scientific Evidence

Science behind unit-based dosing of large muscles — peer-reviewed references

Botulinum toxin type A has been studied in aesthetic medicine since the earliest published treatment of frown lines, and the consensus and pharmacology literature below describes how the different toxin products are characterised, dosed and compared. That body of work is the reason unit-based, conservative dosing is the standard your director follows for large body muscles.

All references carry verifiable DOIs from indexed journals. They are cited here as background on the toxin itself; your own plan is decided by your muscle assessment at consultation.
