Botox - a Toxin with Great Cosmetic Result for Removing Wrinkles

What Is Botulinum Toxin?

Botulinum toxin is a neurotoxic derivative of Clostridium botulinum. There are eight distinct antigenic serotypes of exotoxins, and among these, only A and B are used for various medical indications. Exotoxin A is the most commonly used, and it is more potent than exotoxin B.

Clostridium botulinum bacteria are present in many natural settings, like soil, forests, lakes, and the intestinal tracts of fish and mammals.

Naturally occurring Clostridium botulinum bacteria and their spores are harmless, and the problems only arise when these spores transform and increase the cell population. To a certain extent, the bacteria start to produce Botulinum toxin, a deadly neurotoxin responsible for botulism.

Botulinum toxin is hazardous, and some scientists have found that a crystalline form of the Botulinum toxin can kill 1 million people, and a couple of kilograms can kill every human on the planet.

How Does It Work?

Botulinum toxin is a neurotoxin that targets the nervous system to disrupt the nerve signaling process that stimulates muscle contraction; thus, the drug causes temporary muscle paralysis.

In order to contract the muscle, the Botulinum toxin inhibits the release of neurotransmitters, a chemical messenger (acetylcholine) at the nerve terminal. It impedes the nerve impulse and leads to paralysis of muscles. This is due to the attachment of the acetylcholine to the receptors on the muscle cells, and this causes the cells to contract or shorten.

Thus, Botox injections prevent the release of acetylcholine, which stops the contraction of the muscle cells.

What Are the Uses of Botox?

a) Cosmetic Use of Botox:

• Elimination or cosmetic correction of wrinkles and rhytides on the upper face like crow’s feet wrinkles at the side of our eyes, frown lines or angry lines on the forehead and mid and lower part of the face like the line below eyes, lines around the mouth, chin irregularities and correction of mouth corner.

• Eyebrow lift - Due to aging, if there is a descent of eyebrows, then it can be raised back.

What Are the Contraindications of Botox?

• In the case of neuromuscular disorders like myasthenia gravis, autonomic dysfunction, muscle weakness, etc.

• History of hypersensitivity to this toxin.

• Local infection at the injection site.

• Pregnancy and lactation.

What Is the Procedure for Using Botox?

Preparation of Botox:

Your treating doctor will mix 1 to 2.5 mL of preservative-free normal saline to reconstitute the 100 units of neurotoxin. This prepared solution can be stored at 2 to 8 degrees Celsius for up to four weeks. Its 0.1 mL contains four units of Botox.

Doses:

For forehead wrinkles and frown lines, use 10 to 25 units; for crow’s feet, use 9 to 15 units per side; for bunny lines, 3 to 5 units per side; for chin correction, use 5 to 15 units and neckbands 20 to 50 units.

The Technique of Injection:

Usually, local anesthesia is not required for cosmetic correction of the face, but in the case of palmoplantar or axillary hyperhidrosis, it is required. The toxin is injected with an insulin syringe, which causes very minimal pain. The needle should be used at 45 degrees to a depth of 2 mm to avoid the backflow of toxin.

Instructions to Follow After Procedure:

• An individual in whom the toxin is injected should not recline for 3 to 6 hours to prevent unwanted diffusion of the toxin.

• Not to massage or manipulate the treated area for 4 hours to avoid bruising.

• Not to exercise the treated muscles for the first 2 to 3 hours, like not to frown or raise the eyebrows or smile.

• Wipe off any toxin immediately if present on the skin.

• Maximum effects are seen after 7 to 10 days and last for approximately three months, and in some cases, much longer.
