Body Botoxin Gangnam, Seoul
Body Botox relaxes larger muscles — most often the trapezius (for a smoother shoulder-to-neck line and tension relief) and the calves — so an over-developed muscle gradually softens for a slimmer line. At QD Clinic in Gangnam, Seoul, we assess which muscle is driving the shape first, then plan the dose. A session usually takes about 15–20 minutes with little downtime. (Results vary by individual.)
Who it’s for
- A bulky shoulder line or neck-and-shoulder tension from a developed trapezius
- Developed calf muscles that widen the lower-leg line
- Arm or thigh lines influenced by muscle rather than fat
- Anyone who prefers a non-surgical option with minimal downtime
Body lines can come from muscle, fat or both; examination confirms whether botulinum toxin suits your goal. Fat-related fullness may be better addressed with other options.
How it works
Botulinum toxin type A reduces the contraction signal to the targeted muscle. Over the following weeks, less activity in an over-worked muscle leads to a gradual decrease in bulk, softening the line, while trapezius treatment can also ease tension. Because these are larger muscles, more units are used than on the face, and dosing is planned to keep function comfortable. The effect is temporary.
THE MECHANISM, STEP BY STEP
01Blocks the nerve-to-muscle signal
Botulinum toxin type A blocks the release of acetylcholine at the neuromuscular junction, so the targeted muscle — such as the trapezius or the calf — receives less signal to contract.
02Bulk decreases with less use
With the muscle working less, an over-developed muscle gradually reduces in bulk over the following weeks, softening the line. Because these are larger muscles, more units are used than on the face.
03Trapezius tension can ease
When the trapezius is over-active, reducing its pull may also ease neck-and-shoulder tension alongside smoothing the shoulder line.
04Wears off as activity returns
Signalling recovers over time, so muscle use returns and the effect fades — which is why the treatment is repeated.
Treatment areas
- Trapezius
- The shoulder-to-neck muscle; treated for a smoother line and tension relief.
- Calves
- The gastrocnemius, for a slimmer lower-leg line.
- Arms & thighs
- Where muscle contributes to the line, decided at consultation.
What the procedure is like
- 1Consultation and examination of the target muscle
- 2Cleansing and marking of injection points
- 3Injections distributed across the larger muscle
- 4Brief pressure and aftercare guidance
Time: A session usually takes about 15–20 minutes.
Recovery & aftercare
- Little to no downtime; most people return to daily activities the same day.
- Temporary tenderness, mild bruising or muscle fatigue may occur; strenuous exercise of the area is best paused for a short period.
- Follow the aftercare guidance we provide; line change appears gradually over several weeks.
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
DAY 0 Injection day
Injections distributed across the larger muscle take about 15–20 minutes. Temporary tenderness, mild bruising or a feeling of muscle fatigue may occur. Most people return to daily activities the same day.
DAY 1-3 Settling
Any tenderness or fatigue in the area generally eases. Strenuous exercise of the treated area is best paused for a short period, as advised.
2-6 WEEKS Gradual line change
The line softens gradually as the muscle is used less; larger, denser muscles such as the calves tend to be slower. (Results vary by individual.)
3-4 MONTHS Gradual return
Muscle activity returns gradually and the line slowly fills back. Duration differs with muscle size, dose and activity. (Results vary by individual.)
REPEAT Maintenance
A repeat session is timed at consultation once muscle activity returns, rather than on a fixed date.
Sessions & results
Line change appears gradually over about 2–6 weeks — muscle-bulk areas such as the calves tend to be slower — and typically lasts around 3–4 months. A repeat plan is timed at consultation. (Results vary by individual.)
How it compares
A fuller body line can come from muscle, from fat, or from posture and habit, so the right approach depends on what is driving the shape.
| Comparison | Body Botox | Fat-focused options | Physical & posture care |
|---|---|---|---|
| Approach | Botulinum toxin type A relaxes an over-developed muscle | Addresses fat rather than muscle | Exercise, stretching and posture habits |
| Targets | Muscle-driven bulk such as the trapezius or calves | Fat-related fullness | Tension and muscle-use habits |
| Onset | Gradual over 2–6 weeks | Varies by method | Gradual with ongoing care |
| Duration | About 3–4 months | Varies by method | Depends on continued care |
| Downtime | Little to none | Varies by method | None |
Neither is “better” — they work differently and suit different goals. The right choice is decided after we assess your skin.
Safety & considerations
Possible reactions
- Temporary tenderness, mild bruising or a feeling of muscle fatigue in the treated area
- A short period where the muscle feels weaker during strenuous use
- Slight asymmetry that eases as the effect settles or wears off
- Rarely, an unfamiliar movement in a nearby muscle that typically settles
When to take extra care
- Pregnancy or breastfeeding — let us know at consultation
- Neuromuscular disorders such as myasthenia gravis or Lambert–Eaton syndrome
- Certain medications, including aminoglycoside antibiotics or muscle relaxants — tell your doctor
- A known allergy to botulinum toxin or any ingredient in the product
- Sports or work that need full power from the muscle, or active infection at the injection site — tell your doctor
Whether the line comes from muscle or fat, and the dose that keeps function comfortable, is confirmed at consultation. Effects and duration vary by individual, and side effects may occur.

Pricing
Pricing depends on the muscle treated and the dose, which is larger than for facial areas. Please consult us for a personalized quote.
Frequently asked questions
By easing over-activity in the trapezius, it may relieve neck-and-shoulder tension while smoothing the shoulder line. Suitability is confirmed at consultation. (Results vary by individual.)
Change appears gradually over about 2–6 weeks; larger, denser muscles like the calves tend to take longer. (Results vary by individual.)
That is confirmed by examination. Muscle-driven lines may suit botulinum toxin, while fat-related fullness may be better addressed with other options.
Light daily activity is fine, but strenuous exercise of the treated area is best paused for a short period, as advised at your visit.
Yes. Our doctors consult in English directly, and 中文 / 日本語 can be arranged in advance. Tell us your language on WhatsApp before your visit.
Often considered together
Treatments that are sometimes planned alongside this one, decided at consultation.
+Jaw Botox
The same principle of relaxing a developed muscle is used on the masseter of the face, sometimes planned together for overall balance.
+Fat-focused options
When fullness is partly from fat rather than muscle, other options may be more suitable — sequencing is decided by your doctor.
+Posture & stretching care
For trapezius tension, everyday posture and stretching habits support the result alongside treatment.
