Botulinum Toxin A

Treatments using Botulinum Toxin A (BTX-A) is commonly referred to erroneously as Botox treatments. Botox specifically refers to the brand of BTX-A made by Allergan plc, and BTX-A itself is a neurotoxin that is designed to relax/paralyze muscles, resulting in effective treatment of dynamic wrinkles as well as reduction in muscle size (e.g. jaw muscle slimming or jaw slimming).

The other commonly used brand of BTX-A is Dysport, with Xeomin being the 3rd most popular brand of neurotoxin being used in Singapore. At YVL Medical Aesthetics, we carry all 3 brands of Botulinum Toxin A.

How it Works

BTX-A injections work by relaxing/paralyzing muscles. When used appropriately, relaxation of selected muscle groups on the face allow us to eliminate dynamic wrinkles like crow’s feet and frown lines.

Prominent neck muscle bands may similarly be treated. Prolonged relaxation of muscles also results in reduction of muscle size, allowing for facial slimming through jaw muscle reduction, neck slimming, shoulder slimming and calf slimming.


BTX-A wrinkle treatment may kick in from 12 hours to 1 week after injection, with an average time-to-effect of 2 to 3 days. For muscle slimming, this may take anywhere between 1 to 4 weeks, depending on the size of the muscle and the dosage used.

Each treatment is expected to last between 3 to 6 months in duration.

What to Expect

If you are unsure what you need, you require a consultation at the clinic. Our doctor will help to analyze your active issues and review your treatment options with you.

BTX-A injections are extremely safe, with over a hundred million cases treated worldwide since 1977 for both medical as well as cosmetic indications. Death with BTX-A injections occur only rarely due to a severe allergic reaction known as anaphylaxis. Dying from BTX-A is as likely (if not less likely) as dying from receiving a vaccination.

BTX-A only has a maximum effect of 6 months in duration and all effects associated with it WILL disappear by the 6th month.

Who is Not Suitable

Most individuals are suitable for BTX-A treatments. Our doctor will make a detailed assessment prior to offering treatment.

Post-Treatment Care

After BTX-A treatment, you should avoid massaging or compressing the injection sites for 2 to 3 days. This is to avoid inadvertent spread of the neurotoxin to adjacent muscle groups on the face.

It is often said that strenous activity or anything that increases the the body’s circulation (sauna, alcohol) should be avoided for 1 day, so as to minimize the chances of the the neurotoxin spreading via the blood stream to other parts of the body. However, at the dosages used for cosmetic purposes, systemic spread of BTX-A has never been an issue.


At YVL Medical Aesthetics, we always aim to deliver the most natural results. One should expect to see the wrinkles diminish/face or neck slimming/muscle slimming depending on the treatment area. When used on the face, the complexion also becomes glowy due to an independent effect of BTX-A on the skin.
