Botox is actually the trade name for a substance injected into the skin which is known to inhibit muscle movement โ€“ and that can prevent wrinkles from developing or worsening.

The name โ€˜Botoxโ€™ actually comes from the word โ€˜botulousโ€™ โ€“ which means sausage. Not so glamorous sounding now, eh?

It is called this because the substance is related to a naturally occurring poison โ€“ which can occasionally be found at dangerous levels in bad meat products.

Scarily, high levels of this poison have the ability to paralyse โ€“ and even kill.

However, while it has been described as โ€œthe most poisonous substance knownโ€, it all comes down to purity and dose when used safely for cosmetic purposes.
