A Historical Overview of Botox and Dysport

Injectable aesthetics have revolutionized the beauty industry, providing a non-surgical approach to combat signs of aging. Two key players in this revolution are Botox and Dysport, both forms of Botulinum toxin type A. Let’s take a look at the fascinating history and development of these aesthetic solutions, their uses, benefits, and the future of this sector.

The Birth of Botulinum Toxin

The origins of Botulinum Toxin, or BTX, are rooted in the 19th century. In 1895, Belgian scientist Emile van Ermengem isolated a bacterium, which he named Clostridium botulinum, during an investigation of a food-borne illness outbreak linked to tainted ham. Interestingly, this bacterium produces a neurotoxin, which was later identified as the cause of botulism, a potentially fatal condition characterized by muscle paralysis.

From Poison to Medicine

Fast-forward to the 20th century, BTX took a turn from being a deadly poison to a potential therapeutic agent. German physician Justinus Kerner, in the 1820s, suggested that the toxin could be used therapeutically in small doses. This idea, however, took over a century to materialize.

In 1928, Dr Herman Sommer, at the University of California, San Francisco, first isolated in purified form botulinum toxin type A (BoNT-A) as a stable acid precipitate. During World War II, the toxin was weaponized due to its ability to cause paralysis.

Post-war, Edward J. Schantz, who had been instrumental in botulinum toxin research during the war, produced the toxin for use in scientific studies. In 1978, ophthalmologist Alan B. Scott began the FDA trials for the use of botulinum toxin to treat crossed eyes. In 1989, the drug, then called Oculinum, received its first FDA approval to treat crossed eyes (strabismus) and eye twitching (blepharospasm).

The Dawn of Botox

After acquiring Oculinum from Scott, Allergan renamed it Botox. Initially, Botox was used primarily for therapeutic purposes, including treating strabismus, blepharospasm, and other muscle disorders.

The cosmetic use of Botox was discovered accidentally in 1987 by Canadian eye doctor Jean Carruthers. She noticed that her patients treated with Botox for blepharospasm also saw an improvement in forehead wrinkles. This discovery led to a surge in interest in Botox as an aesthetic treatment.

In 2002, Botox Cosmetic was approved by the FDA to temporarily improve moderate-to-severe frown lines between the eyebrows, popularly known as “glabellar lines”. This marked a significant milestone in the realm of aesthetic medicine, signaling the dawn of an era where signs of aging could be combated non-surgically.

The Emergence of Dysport

While Botox was making waves in the United States, another BTX-A product, Dysport, was being developed in the United Kingdom. Manufactured by Ipsen, Dysport was approved by the FDA in 2009 for the treatment of cervical dystonia and moderate-to-severe glabellar lines in adults.

The difference between Botox and Dysport lies in their purification procedures. Botox is purified through repeated precipitation and re-dissolution, while Dysport is purified using a column separation method. This difference in purification results in varying unit potencies, with 1 unit of Botox being approximately equivalent to 3 units of Dysport.

Botox and Dysport: Beyond Beauty

While Botox and Dysport are best known for their cosmetic applications, they also have several therapeutic uses. Both products have been approved for treating conditions such as cervical dystonia, hyperhidrosis (excessive sweating), and chronic migraines.

Botox has been approved for treating neurogenic detrusor overactivity (urinary incontinence), upper limb spasticity, and even chronic sialorrhea (excessive drooling). Dysport has also been approved for treating upper and lower limb spasticity in adults and children.

The Future of Botox and Dysport

The future of Botox and Dysport looks promising, with research being conducted into a variety of potential new applications. One exciting area of research is the use of Botox for treating depression. Preliminary studies suggest that Botox may have a positive effect on mood, potentially paving the way for a new treatment approach for depression.

Moreover, there’s a growing trend toward using smaller doses of Botox and Dysport for a subtler aesthetic result. Known as “baby Botox”, this approach aims to soften, rather than eliminate, facial lines and wrinkles.

The Safety and Efficacy of Botox and Dysport

Research has shown that both Botox and Dysport are effective treatments for their approved indications. When administered by trained professionals, these treatments are generally safe. However, as with any medical procedure, there can be potential side effects.

Common side effects include temporary bruising, swelling, or pain at the injection site. More serious side effects, such as muscle weakness or difficulty swallowing, are rare and usually associated with higher doses or improper injection techniques.

The Role of Botox and Dysport in Modern Aesthetic Medicine

The introduction of Botox and Dysport has had a profound impact on the field of aesthetic medicine. They have transformed the way we approach aging, allowing for non-surgical interventions that can dramatically improve a person’s appearance.

With the potential for new applications continually being researched, the future of Botox and Dysport in both medical and aesthetic fields seems bright. As our understanding of these treatments continues to evolve, so too will their role in helping individuals achieve their aesthetic goals.

The Impact of Botox and Dysport on Society

The widespread use of Botox and Dysport has undoubtedly had a significant impact on society. They have not only changed the face of aesthetic medicine but also altered societal perceptions of aging.

The popularity of these treatments has led to a shift in societal beauty standards, with a smooth, wrinkle-free complexion often seen as the ideal. However, it’s important to remember that these treatments are not for everyone and that a natural aging process is a normal part of life.

The Importance of Professional Guidance

While Botox and Dysport have a good safety profile, trained professionals must administer these treatments. Incorrect administration can lead to unwanted side effects and unsatisfactory results. Always consult with a qualified healthcare provider before deciding to undergo any aesthetic treatments.


The journey of Botox and Dysport from toxins to aesthetic treatments is a testament to the power of scientific discovery and innovation. These treatments have revolutionized the field of aesthetic medicine, offering a non-surgical solution to combat signs of aging.

However, while these treatments can help improve physical appearance, it’s essential to remember that beauty is more than skin deep. Achieving a balanced sense of self-confidence and self-acceptance is just as important, if not more so, than eliminating wrinkles or enhancing features.

In aesthetic medicine, Botox and Dysport have undoubtedly proven their worth as potent tools in the fight against aging. Their evolution from deadly poisons to therapeutic agents and now to aesthetic marvels is a fascinating journey that underscores the power of innovation and the endless possibilities of modern medicine.
