Botulinum toxin A (BTA) is a substance originally found in the bacteria Clostridium botulinum. BTA’s primary action is the blockade of signal transmission at the nerve endings that connect the nerves to the muscles and glands. In clinical practices, BTA’s is used to weaken a particular muscle or muscle group and suppress glands activity(for example, sweat glands).


In aesthetic practice, BTA is commonly used to inject into discrete facial muscles to reduce wrinkles and produce skin tightening and lifting. Injection of BTA also can enhance the skin complexion of the face by suppressing the overactivity of the oil glands and sweat glands in the skin (see Microbotox). BTA can treat excessive sweating in the armpit and hand due to the overactivity of the sweat glands.


The duration of action for BTA is usually around six months. The injection of BTA needs to repeat regularly every six months to maintain the desired effects.


There are many different brands of BTA used in aesthetic practice. The brand of the BTA that we used in our clinic is BOTOXÒ.

  2. Eyebrow lifting.
