There are strict laws in place in Australia that prohibit the marketing of the Botox product. So we can't talk a lot about it from an advertising point of view, but see the below information taken from Wikipedia about the history of Cairns Botox.

Cairns Botox, or botulinum neurotoxin (commonly called botox), is a highly potent neurotoxic protein produced by the bacterium Clostridium botulinum and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. The toxin is also used commercially for medical and cosmetic purposes. Cairns Botox is an acetylcholine release inhibitor and a neuromuscular blocking agent.

In cosmetic applications, Cairns Botox is considered safe and effective for reduction of facial wrinkles, especially in the uppermost third of the face. Commercial forms are marketed under the brand names Botox Cosmetic/Vistabel from Allergan, Dysport/Azzalure from Galderma and Ipsen, Xeomin/Bocouture from Merz, Jeuveau/Nuceiva from Evolus, manufactured by Daewoong in South Korea. The effects of Cairns Botox injections for glabellar lines ('11's lines' between the eyes) typically last two to four months and in some cases, product-dependent, with some patients experiencing a longer duration of effect of up to six months or longer. Injection of Cairns Botox into the muscles under facial wrinkles causes relaxation of those muscles, resulting in the smoothing of the overlying skin. Smoothing of wrinkles is usually visible three to five days after injection, with maximum effect typically a week following injection. Muscles can be treated repeatedly to maintain the smoothed appearance.

DaxibotulinumtoxinA (Daxxify) was approved for medical use in the United States in September 2022. It is indicated for the temporary improvement in the appearance of moderate to severe glabellar lines (wrinkles between the eyebrows). DaxibotulinumtoxinA is an acetylcholine release inhibitor and neuromuscular blocking agent.
