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 nerve endings that connect nerves to 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 skin complexion of the face by suppressing the overactivity of oil glands and sweat glands in the skin (see Microbotox). BTA can treat excessive sweating in the armpit and hand by suppressing  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 at regular intervals 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 BOTOX™.




Cosmetic applications of BTA:

    1. Reduce wrinkles on the face, including the frown lines, forehead wrinkles, wrinkles at the corner of the eyes (crow feet), wrinkles around the eye, wrinkles around the mouth, wrinkles on the nose (bunny lines), wrinkles and bands on the neck.
    2. Eyebrow lifting.
    3. Reduce the size of the masseter muscle at the angle of the jaw. Enlarged masseter muscle gives rise to a square face appearance. Smaller masseter muscle makes the face appear oval and slimmer.
    4. Lift and tighten the jawline (Nefertiti Lift).
    5. Reduce chin dimpling.
    6. Smoothen the lines at the angle of the mouth.
    7. Treat mild to moderate cases of a gummy smile.
    8. Treatment of facial asymmetry.
    9. Treatment of hypertrophic scars (see Scars Treatment).




Therapeutic applications of BTA:

    1. Focal hyperhidrosis (excessive sweating) involving the armpit, palm, soles, face.
    2. Abnormal eye twitching (blepharospasm)
    3. Migraine headache.
    4. Dystonia (abnormal involuntary muscle contraction).
    5. Hemifacial spasm.
