The calf slimming treatment involves a few injections of Botulinum Toxin to the calf muscle(s), and the circumference of the calves will start to reduce noticeably. It could block peripheral motor nerves to the leg triceps, which has the effect of reducing the muscle bulk, and thus giving a more streamlined contour to the leg. The treatment is simple and akin an insect bite, as some would call it. Thus, it has no need for anaesthesia. The optimal result comes after approximately three months.
