How does Botox Work?

Botox injections can be used to treat various muscular conditions medically while cosmetically it can help to eliminate lines and wrinkles by paralyzing muscles temporarily.

Botox cosmetic med spa injectable contains a neurotoxin known as botulinum. The bacterium Clostridium botulinum produces this neurotoxin.

Fiala Aesthetics Medical Spa, led by astute board certified plastic surgeon Dr. Thomas Fiala, provides Botox to patients in Orlando, Altamonte Springs, FL, and surrounding locations in this magnificent part of the country.

Important Facts

Some key facts on Botox are as follows:

  • Botox is the most sought-after non-surgical med spa cosmetic treatment, and over 6 million patients receive Botox treatments every year.
  • Clostridium botulinum produces a neurotoxin from which Botox is derived. This bacterium is naturally found in the environment where it remains mainly inactive and non-toxic.
  • Botulinum toxin can decrease the appearance of wrinkles and fine lines by paralyzing the overactive muscle responsible for wrinkle formation.
  • Botox is also used in the treatment of profuse sweating, migraines, certain bladder and bowel conditions and muscular disorders.


When the Botulinum toxin is injected into humans in very tiny doses, it prevents signals from the nerve cells to reach the targeted muscle. This paralyzes the overactive muscle to reduce the appearance of wrinkles and fine lines in the area.

For the muscles to contract, the nerves secrete a chemical messenger called acetylcholine. This is a neurotransmitter which the nerve releases at the point where the endings of the nerve meet the muscle cells. Acetylcholine attaches itself to the muscle cell receptors causing these cells to constrict or shorten.

The botulinum toxin when injected into the muscle releases acetylcholine which prevents the contraction of the muscle cells. This toxin leads to a decrease in the abnormal muscle contraction enabling the muscles to become less tight.


Botulinum toxin is mainly used to mitigate the appearance of fine lines and wrinkles on the face. Other than cosmetic applications, Botox can effectively treat various medical conditions such as migraines, eye squints, excess sweating, and incontinence.

At present, the botulinum toxin is used in the treatment of more than 20 different medical conditions while more applications of this toxin are being investigated. Botulinum toxin has received approval for the below mentioned therapeutic uses:

  • Idiopathic rotational cervical dystonia (severe muscle spasms in the neck and shoulder).
  • Blepharospasm (eyelid spasm).
  • Severe primary axillary hyperhidrosis (excessive sweating).
  • Chronic migraine.
  • Post-stroke upper limb spasticity.
  • Detrusor (bladder wall muscle) overactivity resulting in urinary incontinence.
  • Hemifacial spasm.
  • Overactive bladder.
  • Glabellar lines (frown lines between the brows).
  • Canthal lines (crow’s feet).
  • Strabismus (crossed eyes).

Botulinum toxin also has the following off-label (not approved) applications:

  • Achalasia (a throat condition that makes swallowing challenging).
  • Sialorrhea (production of excessive saliva).
  • Anal fissure and anismus (anal sphincter dysfunction).
  • Allergic rhinitis (hay fever).

Botox – FDA Approved for Canthal Lines

Crow’s feet (lateral canthal lines) are the fine lines that radiate from the eyes’ outer corners. Repetitive movements such as frowning, squinting, smiling, and other expressions of the face are usually responsible for the formation of these lines.
