Botulinum toxin preparations have been used in cosmetology for quite a long time, and during this time they have managed to prove themselves from different angles.

Individual features of the body of each patient determine its response to the introduction of botulinum toxin, the duration of the drug and the severity of the effect.

Lifting restrictions on botulinum toxin injections

Scientists have found that the time of active action of botulinum toxin preparations on neuromuscular junctions is only 30 seconds. After this time, the drug is no longer in the muscles, but the result of its work remains – interruption of the transmission of nerve impulses to muscle fibers. In this regard, some restrictions on injections of botulinum toxin preparations:

have been lifted

• there is no longer a need for the patient to be in an upright position for 4 hours after the procedure, as well as to refuse to play sports, drink alcohol, visit the sauna, and so on;
• 30 seconds after the injection of the botulinum toxin preparation, meso-cocktails, biorevitalizants, fillers or threads can be injected into the same area;
• repeat injections of botulinum toxin preparations can be as often as necessary for the patient, however, it is recommended to inject into the same area no more than once every two months.

Full face – optimal method of administering botulinum toxin preparations

For a long time, specialists have been injecting botulinum toxin preparations into certain areas of the face that required correction. Currently, it is believed that the optimal method for administering botulinum toxin preparations is full face, that is, injections into different areas of the entire face.

This is explained by the fact that the blockade of certain muscles of the face provokes compensatory hypertonicity of other muscles, which, consequently, leads to the formation of new mimic wrinkles. For example, the introduction of botulinum toxin into the muscles between the eyebrows often causes hypertonicity of the muscles of the nose and the inner corner of the eye. It is important to distribute the dose of the drug over the entire face so that the ratio between depressor and levator muscles is 3:1.

At what age should botulinum toxin injections be done?

With regard to age restrictions for injections of botulinum toxin preparations, the following recommendations can be distinguished today:

• up to 25 years, the use of botulinum toxin in minimal doses is indicated for significant activity of certain muscles of the face;
• from 25 to 35 years of age, active prevention of mimic wrinkles is recommended with full doses of botulinum toxin preparations;
• 35-45 years – wrinkle prevention continues with higher doses of botulinum toxin injections;
• 45-55 years – botulinum toxin preparations are administered at lower doses, in combination with procedures that promote collagen production;
• after 45-55 years – the administration of botulinum toxin preparations in low doses can give a good rejuvenation result for those women who take hormone replacement therapy.
