A new formulation of Botox could last longer according to medicalnewsbulletin.com. Currently, Botox is seen as an effective treatment for wrinkles, however, it has long been known that it needs regular top ups for the effects to continue. Therefore, this new development could mean fewer trips to the clinic and less overall cost for the patient.
Botox works by temporarily paralysing the muscles by blocking the signals from the nerves. Due to this, the skin does not wrinkle and appears smooth and flat. Canadian scientists conducted a large-scale trial which studied the effects of the new formulation in comparison to the current one. The trial focused on the forehead lines between the eyes (glabellar lines). Over two hundred and fifty people took part. The results showed that while both formulations were effective at reducing wrinkles the new formulation lasted, on average, five weeks longer than the current option. This has prompted three more wide-scale trials. The aspirations are to get the new formula approved for use in the near future.
