Is this you?
This treatment may be worth considering if
- Calves that look bulky from muscle development
- A noticeably broad trapezius giving the neck and shoulder line a heavy look
- A muscular silhouette from athletic training
- Wanting to address a muscle-based contour rather than a fat-based one
What this treatment is
Body-area neurotoxin injects Xeomin (Germany) into specific muscles like the calves or trapezius, relaxing muscle tension to improve a bulky, muscular silhouette. It has limited effect on fat-based bulk, so your doctor needs to identify the cause first.
What you can expect
Changes you'll notice afterward
- A muscle-based bulky calf or trapezius contour gradually relaxes and slims
- Results gradually appear within 1 to 4 weeks after injection
- Almost no downtime, so you can return to daily activities the same day
- Repeat treatment is usually needed to maintain results, depending on your metabolism and dose
Actual results and sensation vary by person. Your doctor will explain what to expect for your skin at your consultation.

How your doctor decides
Your doctor first palpates the area to confirm whether the bulk is muscle-based or fat-based, since only muscle-based bulk responds to neurotoxin injection, and decides the dose based on muscle mass.

Frequently Asked Questions
Does body neurotoxin work on fat-based bulk too?
Body neurotoxin mainly targets muscle-based bulk. Fat-based bulk needs a fat-reduction treatment or another body program instead, so your doctor palpates the area first to identify the cause.
How long do results last?
It depends on your metabolism and dose, and repeat treatment is usually needed to maintain results. Your doctor will explain the expected frequency at your consultation.
Does it hurt? Do I need numbing?
You'll feel mild stinging during injection, but additional numbing usually isn't needed. Most people find the sensation manageable.
How soon will I see results?
Results usually appear gradually within 1 to 4 weeks after injection rather than right away, and how long they last depends on your metabolism and dose.
