Botulinum Toxin is a product which has been used in the market for a long time, initially to treat neurological pathologies and later in aesthetic medicine. It is mainly used to combat wrinkles around the eyes (pericular), on the forehead, and between the eyebrows, but also – in a more reserved form – on the lower part of the face (neck, upper lip and chin). Its effects are ephemeral, from 4 to 6 months, but its results are wonderful. Repeated use prolongs the durability period.
