Arm Slimming Botox explained

Arm slimming Botox, known as 팔뚝 보톡스 in Korea, treats arms that look bulky because of muscle. The most common target is the deltoid, which can make the shoulder and upper arm look broad. It does not tighten skin or remove fat under the arm.


How Arm Slimming Botox works

The doctor feels the muscle while you tense your arm and marks a grid over the bulky part. Toxin is injected at many shallow-to-mid depth points into the muscle. Over a few weeks, the muscle becomes less active and shrinks slightly, so the outline looks softer. Doses are planned so that lifting and daily tasks stay normal.


Who Arm Slimming Botox is for

  • Firm, muscular upper arms or rounded shoulders
  • People who build arm muscle easily from sport or work
  • A softer line in sleeveless clothing
  • Combining with trapezius Botox for the shoulder line
  • Combining with fat reduction when both fat and muscle are present


Who should avoid Arm Slimming Botox

  • Loose, crepey skin on the upper arms
  • Arm fullness that is mainly fat
  • Athletes or anyone who needs full arm strength
  • Pregnant or breastfeeding women
  • People with myasthenia gravis or other nerve-muscle disorders


What happens at the appointment

  1. Consultation and a pinch test to check muscle versus fat
  2. Marking of injection points while you tense the arm
  3. Cleansing and quick injections across the muscle
  4. Short check for bleeding points
  5. Aftercare advice and a review at about 4 weeks


Aftercare and flying home

  • Avoid heavy upper-body workouts for about 1 week
  • Do not massage the arms for the first day
  • Avoid saunas and alcohol for 24 hours
  • Carry light bags for a few weeks if your arms feel tired
  • Flying is fine the next day


Side effects and risks

  • Tenderness and small bruises
  • Mild arm weakness when lifting heavy items
  • Uneven results between the arms
  • Rare: flu-like symptoms with large total doses
  • Rare: allergic reaction
