Botulinum toxin is a neurotoxin made by a bacterium called Clostridium botulinum.
Botulinum toxin works locally by blocking acetylcholine release, resulting in temporary muscle paralysis. The final effect is a temporary chemodenervation at the neuromuscular junction without causing any physical damage to the nerve structures.
Botulinum toxin should not be confused with filler treatments. Botulinum toxin relaxes the muscles but does not increase the volume of the treated area.
It is a very safe drug, used for more than 20 years in many medical specialties, such as neurology, ophthalmology, and others.
Its popularization and more widespread use is due to aesthetic medicine, due to its preventive, corrective and rehabilitative effect on different skin alterations (seborrhea, aging, etc.) and especially its indication to treat expression wrinkles. It is the ideal treatment to make expression wrinkles disappear because it works by relaxing the muscles of the face that produce them. Especially indicated for “crow’s feet” wrinkles, forehead and frown.
The duration of the treatment varies depending on each person and their facial characteristics, ways of moving the face, skin type, age. The normal duration is between 3 months and 6 months. The treatment is usually repeated every 4 to 5 months, before the effect disappears completely.
