Botulinum toxin, best known as Botox, has come a long way from its dark origins as a deadly bacterial toxin. Today, it’s one of the most widely used cosmetic treatments for softening wrinkles and fine lines. But how did a dangerous toxin become a go-to beauty treatment? And with so many brands now available—like Dysport, Xeomin, Letybo, and Nuceiva—how do they differ? Let’s take a closer look at the fascinating history of botulinum toxin and how it became a game-changer in both medicine and aesthetics.
How Botulinum Toxin Was Discovered
The story of botulinum toxin begins in the 1820s when a German doctor, Justinus Kerner, investigated a strange illness caused by contaminated sausages. He found that the illness led to muscle paralysis and eventually death, and he suspected it was caused by a toxin. He even suggested that this toxin might have medical benefits if used correctly—long before anyone knew how to do so.
In 1895, a Belgian scientist, Emile Van Ermengem, identified the bacteria responsible for producing this toxin: *Clostridium botulinum*. Scientists later discovered that this toxin worked by blocking nerve signals to muscles, causing temporary paralysis. While this made it deadly in food poisoning cases, it also opened the door to potential medical uses.
Medical Research to a Cosmetic Breakthrough
Fast-forward to the 1950s, when scientists were experimenting with botulinum toxin to treat muscle-related conditions. In the 1970s, a Canadian eye doctor, Dr. Alan Scott, started using it to help patients with crossed eyes (strabismus) and uncontrollable eye twitching (blepharospasm).
By the 1980s, doctors began noticing that patients treated with botulinum toxin for eye conditions also experienced smoother skin around their eyes—an unexpected but welcome side effect. In the early 1990s, Dr. Jean Carruthers, a Canadian ophthalmologist, and her husband, Dr. Alastair Carruthers, a dermatologist, started researching botulinum toxin’s cosmetic benefits. They realised that tiny injections of botulinum toxin could temporarily relax facial muscles, reducing wrinkles.
This led to the FDA approving Botox for cosmetic use in 2002, specifically for treating frown lines. Since then, its popularity has skyrocketed, with millions of people around the world using it to smooth wrinkles, prevent fine lines, and even treat medical conditions like migraines and excessive sweating.
Botulinum toxin type A, commercially known as Botox, was first approved by Australia’s Therapeutic Goods Administration (TGA) for medical use in 1999. It quickly spread to Hobart, Tasmania, the location of Heart Aesthetics Hobart. Subsequently, in 2002, it received approval for cosmetic applications, specifically targeting vertical frown lines.
Botox vs. Other Brands: What’s the Difference?
While Botox is the most well-known name, it’s actually just one of several brands of botulinum toxin available today. Other brands, like Dysport, Xeomin, Letybo, and Nuceiva, offer similar wrinkle-relaxing effects but with slight differences in how they work.
While all these brands work similarly, the differences in onset time, spread, and protein composition mean that some might be better suited to certain treatments than others.
Why Is Botulinum Toxin So Effective for Wrinkles?
Wrinkles form when facial muscles repeatedly contract over time—like when we frown, squint, or raise our eyebrows. Botulinum toxin works by temporarily blocking the nerve signals to these muscles, allowing them to relax. This softens the appearance of wrinkles and can even prevent new ones from forming.
Unlike volumising treatments, which add volume to plump up the skin, botulinum toxin is best for treating dynamic wrinkles—the lines caused by repeated facial movements. This is why it’s commonly used for:
– Forehead lines
– Frown lines (between the eyebrows)
– Crow’s feet (around the eyes)
– Bunny lines (on the nose)
– Lip lines and gummy smiles
It’s also used preventatively, with younger patients opting for treatment to slow down the development of deep wrinkles before they even start, often referred to as “baby Botox”
The Future of Neurotoxins
The world of botulinum toxin is constantly evolving. Researchers are working on longer-lasting formulations, faster-acting options, and even new uses beyond aesthetics. In the future, we may see neurotoxins that last six months or more, reducing the need for frequent top-ups.
With new brands entering the market, patients now have more choices than ever, allowing treatments to be tailored even more precisely to individual needs.
