Quick answer · What is Arm Slimming Botox?

Arm slimming Botox is a non-surgical treatment for upper arms that look thick because of muscle. Botulinum toxin is injected into the bulkiest part of the arm muscle, usually the triceps, which then works less and gradually reduces in volume. A session takes 20–30 minutes with no downtime. Changes usually appear from 2–4 weeks, peak around 6–8 weeks and typically last 4–6 months.

How it works

Muscle that works less gradually takes up less space

When the triceps or other upper-arm muscles are well developed, they can make arms look broad in sleeveless clothing. Botulinum toxin lowers their activity, and over several weeks the muscle softens and slims. It does not remove fat or tighten loose skin.

  1. Arm assessment

    Your doctor checks muscle thickness, fat and skin laxity with your arm relaxed and flexed, then marks the injection area.

  2. Mapped injections

    Botulinum toxin is spread across the marked points on the back of each arm with a fine needle.

  3. Gradual change

    The arm feels softer over two to four weeks, with the slimmest look usually at six to eight weeks.

FAQ

Arm Slimming Botox questions we hear every day

Does arm Botox hurt?

Most patients feel a series of small pinches. Numbing cream or cooling can be used, and the session is short.

Will my arms feel weak?

Daily tasks are not usually affected, but some people notice pushing exercises such as push-ups feel harder for a few weeks. Tell your doctor if you train regularly.

When will I see results?

Arms usually start to soften in two to four weeks, with the main effect around six to eight weeks. Results typically last four to six months.

What if my arms are mainly fat or loose skin?

Botox only reduces muscle. For fat or laxity, your doctor may suggest fat-dissolving injections or a skin-tightening device instead.

What should I avoid afterwards?

Avoid heavy arm workouts, massage, saunas and alcohol for a couple of days.

How much does arm slimming Botox cost in Myeongdong?

Price for arm slimming Botox depends on the dose needed for both arms. The same price list applies to every nationality and is given to you in writing before treatment. See our filler and botox price list.
