One of the most common reasons for patients to visit cosmetologists is wrinkles in the upper part of the face. Their formation occurs already at a young age and is especially pronounced in persons prone to vivid mimic accompaniment of emotions of surprise and frown.
Proper use of botulinum toxin preparations is an effective method of correcting expression wrinkles on the forehead, with the help of which patients regain a youthful, beautiful appearance.
In more detail, the method of introducing botulinum toxin preparations for the correction of wrinkles on the forehead, in the area between the eyebrows, as well as "crow's feet", are described on estet-portal.com in this article.
Forehead wrinkle formation causes: anatomical background
The formation of horizontal wrinkles in the forehead area is due to the dynamic action of the frontalis muscle, the main function of which is to raise the eyebrows and wrinkle the skin of the forehead. Anatomically, it is located in such a way that in some areas it is intertwined with antagonist muscles: the circular muscle of the eye, the muscle of the proud, the muscle wrinkling the eyebrow.
Excessive weakening of the frontalis muscle without adequate action on the antagonist muscles can lead to a downward shift in the level of the eyebrows.
The anatomical features of the structure of the upper part of the face must be taken into account when correcting the horizontal muscles of the forehead.

Botulinum toxin injections should be performed in the place of maximum tension of the frontalis muscle. The number of injection points is determined by the doctor in each individual case and depends on the individual characteristics of the patient. All of them should be located 2 cm above the eyebrow line, along one line or in a V-shape.
If the patient has short eyebrows (eyebrow length less than 12 cm), it is advisable to use no more than 4 injection points and a relatively lower dose of botulinum toxin. The drug is injected into the muscle or deposited above it in order to smooth out horizontal wrinkles of the forehead and correct the asymmetry of the eyebrows.

To obtain an additional result, the drug is additionally injected into the descending muscle group of the interbrow region in the lateral section of the orbicular muscle of the eye.

During the brow wrinkle correction procedure, the patient must be in a sitting position.
When carrying out the procedure for correction of the interbrow region, it is advisable to inject the botulinum toxin preparation into the area above the supraorbital ridge and lateral to the supratrochlear vessels.
After the injection is completed, the needle is slowly pulled outward, with its end superficially under the skin, and then re-moved up to a distance of about 1 cm above the pre-injection point – into the circular area of the muscle of the eye, and an additional dose of botulinum toxin is injected.
In the case of a horizontal position of the eyebrows, an additional injection is performed 1 cm above the superciliary arch along the mid-pupillary line. The intersection of the eyebrow with the medial canthus along the midline is the point of injection of the drug in order to weaken the muscles of the proud.

Method of botulinum toxin injection for crow's feet correction
"Houndstooth" - wrinkles in the outer corner of the eye – are formed under the dynamic influence of the circular muscle of the eye.
In order to determine the points of injection of botulinum toxin preparations, the patient must be asked to smile: "crow's feet"; become clearly visible.
First point of administration of the drug – center of crow's feet. In most cases, it is located 1 cm lateral to the outer eye socket. The second and third injection points are localized 1-1.5 cm above and below the first point, respectively.
If "crow's feet" are localized below the projection of the lateral canthus, the points of injection of the drug should be outward in relation to the vertical line drawn through the outer edge of the orbit. When injecting botulinum toxin preparations in this case, the patient should not smile, as this can lead to an effect on the lateral complex of the mimic muscles.
