Botox is the most common name used to refer to the botulinum toxin produced by the bacterium Clostridium botulinum, which is industrially purified and applied in small doses in certain areas of the face to promote a tightening effect. The results are the softening of fine lines and wrinkles on the face, caused by several factors such as natural aging, sun exposure, smoking, and poor diet.
The main cause of fine lines is the natural contraction of facial muscles. These changes can appear on the forehead, in the space between the eyebrows, around the eyes (crow’s feet), on the furrows between the nose and mouth, among others.
The injection of botulinum toxin in these areas causes neuromuscular blockade, partially or completely limiting muscle contraction.
Topical anesthetics are usually applied before the injections, which do not leave scars. The results are not permanent and new applications every few months are required to maintain the effects.
Although it is a simple and common procedure, Guilherme Graziosi M.D. recommends that the decision to take botox injections is taken after a thorough evaluation with the plastic surgeon.
