Botulinum Toxin is a neurotoxic protein produced by bacterium Clostridium botulinum. It works by temporarily paralysing the neurotransmitters in the treated area, which send signals to the brain to move the muscle . It has been used in the medical field for many years to treat various conditions such as overactive bladder and hyperhydrosis. In Aesthetics it is successful at reducing overactive muscle movement and expression lines resulting in reduction of wrinkles and lines. Results can last around 3 or 4 months.
