How Does Botox Work?

Botox, a medical and cosmetic treatment manufactured by Allergan, is a well-known injectable that has been around for more than 30 years. Such a long history on the market earned it a good reputation and a huge number of people who have already received at least one Botox shot.

But what exactly makes neurotoxin-based Botox safe? Are there people who cannot use it? And is it even legal to order Botox Allergan online? Read further to unlock the answers to these and other related questions.

What Is Botulinum Toxin?

Botulinum toxin type A (BtA) is a substance produced by an anaerobic bacterium clostridium botulinum. In big doses, it can be dangerous and cause serious adverse reactions, including such life-threatening diseases as botulism.

BtA has made its way to the medicine and cosmetic industry due to its ability to reduce movements in the injected muscles. The injection blocks signal from the nerves, thus preventing muscles from contracting and creating repetitive expressions - the most common source of facial wrinkles in people over the age of 35-40 years old.

Is It Legal to Order Botox Allergan Online?

Patients treated with Botox can purchase the injectable online as long as they have a valid prescription from their medical provider.

It's possible to order Botox Allergan from Canada, as the loophole in American legislation allows it. However, you will still need to download a prescription, otherwise, an online pharmacy won't be allowed by Canadian law to ship the package to you.

The list of people who can order Botox Allergan without a prescription includes nurses, dentists, practitioner assistants, board-certified dermatologists, and surgeons. Keep in mind that legislation varies from one state to another. If you are a health worker, make sure to double-check whether it is legal for you to order Botox online.

Is Injection of Botox Safe?

Since BtA is associated with an increased risk of botulism, why was it approved by the FDA for medical and cosmetic purposes in 1989 and 2002 respectively? The point is that in Botox, there is so little neurotoxin it is extremely unlikely to cause serious symptoms. Naturally, a toxin is still a toxin, and it's important to find an experienced injector to deliver the solution.

The amount of BtA used in Botox Allergan is enough to only temporarily paralyze muscles responsible for repetitive facial expressions. This way, the number of mimic wrinkles reduces dramatically, and a patient's face looks younger than it used to.

Other signs of aging that Botox treats are:

  • Severe forehead lines;
  • Glabellar lines;
  • Crow's feet;
  • Marionette lines;
  • Nasolabial folds, and others.

As for its medical use, doctors use an injection of Botox to treat chronic migraine, cervical dystonia, hyperhidrosis, and other conditions.

Who Can't Be Treated with Botox?

Using botulinum toxin prior to a talk with a doctor is not advised. Despite its safety, some people cannot be treated with botulinum toxin injectables. Make sure to discuss all your medical conditions with a healthcare provider before receiving a further injection.

Botox contraindications include:

  • Muscle or nerve conditions;
  • Skin infection;
  • History of bad reaction to BtA injectables;
  • Increased risk of an allergic response, and others.

When used incorrectly, Botox may cause:

  • General muscle weakness;
  • Asymmetry and other abnormal facial change;
  • Spread of toxin effect outside the injection area;
  • Nerve damage, and other adverse events.

Still, not all side effects are dangerous. For example, patients treated with BtA can experience certain injection site reactions. As long as they don't cause significant discomfort, they can be left untreated. However, if side effects are severe, prompt medical therapy may be required.


Botox is an effective and time-tested treatment with a huge fanbase, especially in the USA. However, American prices leave much to be desired, hence more and more customers consider ordering their Botox treatment from Canada.

Luckily, USA legislation allows Canadian pharmacies to ship cosmetic and medical injectables to American citizens. This way, it becomes possible to order Botox Allergan from Canada at a reasonable and competitive price. Just make sure that you have a valid prescription from your doctor or, if you are a medical officer, that you are allowed to purchase BtA-based injectables online.
