Quick answer · What is Shoulder Slimming Botox?
Shoulder slimming Botox, or trap Botox, is a non-surgical injection into the upper trapezius, the muscle between the neck and shoulders. Botulinum toxin reduces its activity so the muscle gradually slims, making the neck look longer and the shoulders softer. A session takes 20–30 minutes with no downtime. Change usually begins at 2–4 weeks, peaks around 6–8 weeks and typically lasts 4–6 months.

How it works
A slimmer trapezius, a longer-looking neck
A well-developed upper trapezius can make the shoulders look high and square and the neck look short. Botulinum toxin lowers the muscle's activity, and over several weeks its bulk reduces. Doses are balanced so you keep normal shoulder movement; some patients also feel less shoulder tension.
-
Shoulder assessment
Your doctor checks trapezius thickness and shoulder height while you shrug and relax, and marks the bulkiest area on each side.
-
Mapped injections
Botulinum toxin is spread across the upper trapezius with a fine needle, avoiding the deeper neck structures.
-
Gradual slimming
The muscle softens over a few weeks, with the clearest change in neck length and shoulder line at six to eight weeks.
Inside the clinic
A quick visit, and a softer shoulder line over the weeks after
Treatment takes place in a private room and most patients return to their plans straight away. The trapezius relaxes gradually, so the neck and shoulder line typically looks softer over several weeks.
A good fit if you…
- Have bulky, raised trapezius muscles that shorten your neck line
- Want a softer, more elegant shoulder silhouette

- Prefer a non-surgical option with no recovery time
Talk to your doctor first if you…
