Botox is a brand name for botulinum toxin type A, a neurotoxic protein that is injected into specific muscles with a thin needle to reduce the appearance of wrinkles. It prevents the release of certain chemical signals and messengers coming from nerves which provide a temporary reduction in muscle contraction and movement.
Other brands of botulinum toxin available in the UK include Bocouture, Azzalure, Letybo and Nuceiva. New brands are emerging, but these are currently the most well-established and widely used.
They are all approved for cosmetic use in adults.
