Arms (Fat Dissolving)

Arms often develop pockets of fat under the upper arm, which in turn makes people self-conscious. Arm fat-dissolving injections are a great way to bring back confidence and give a slimmer look to arms.

On the day of treatment


  • We will go through your consent form, which will have been emailed before the session to you, and you will then be asked to sign a physical copy.
  • The doctor will then cleanse your skin so that he can assess it.
  • During his assessment, he will look at skin thickness and quality along with the underlying muscles to determine the injection points needed.
  • The target area will be numbed if necessary and then treated with a microfine needle to minimise discomfort.

Our Process

A specific type of injection that targets the fat cells in the body, Fat-dissolving treatments are becoming more and more popular as a non-surgical option for reducing fat in different areas of your body. By using Deoxycholic acid (which is created in the gallbladder) in a higher dose to target fat cells.

Typically, it will take a few sessions for the fat-dissolving treatment to take effect. With the arms, the area will be assessed at the beginning to see how many sessions are needed. It takes between 30-45 minutes per session and you will begin to notice effects after 1-2 weeks.


  • It is important to massage the treatment area after treatment to ensure the product is dispersed as evenly and thoroughly as possible. Follow the rule of 5’s for optimal results (massage: 5 times a day x 5 minutes x 5 days). Start this process 3 hours after your treatment, or the following morning for late evening treatments.
  • You might experience swelling and bruising the day after your procedure, which is entirely normal and typically subsides within 5-7 days. To mitigate this, refrain from consuming alcohol 24 hours before and after your treatment.
  • Avoid applying heavy makeup or unnecessarily touching the treated area for 6 hours to minimise the risk of infection. Additionally, steer clear of Vitamin C, Retinol, AHA, and BHA skincare products for 24 hours post-treatment to allow for proper settling.
  • Avoid anti-inflammatory or steroid medications for 5 days after treatment.
  • Abstain from engaging in strenuous exercise such as weight training or cross-fit for 24 hours, as it may occasionally cause the treatment to move to unintended areas. Stay away from saunas, jacuzzis, or hot baths for 24 hours post-procedure, as the heat can result in treatment migration.
  • Limit alcohol intake to reduce the risk of bruising, and avoid sleeping on the treated area the night following your treatment.
