Forehead wrinkles are expression lines induced by repeated contractions of the frontalis muscle.
Botulinum toxin injection:
6 points of botulinum toxin injections prevent the frontalis muscle from contracting, thus erasing forehead wrinkles.
The injection points in the frontalis muscle are the blue points.
If we refer to the beauty criteria of the ancients, to the rules of proportion used in drawing, and to various surveys and studies, there are many criteria for qualifying a face as beautiful. Does the forehead play a part in this criterion?
The first of these criteria is symmetry, creating a harmonious, reassuring whole. Next come mathematical criteria: proportions and distances.
The famous rule of three thirds is particularly important: the face must be divided into three thirds (i.e. equal in height):
- The first third runs from the base of the chin to the base of the nose,
- the second from the base of the nose to the eyebrow line
- then the last is represented by the forehead.
In addition, the size of the head must correspond to one eighth of the total height of the body. Similarly, the ideal distance between the eyes (1/5th of the width of the face) and the proportions of the lips (1/3 -2/3) obey strict rules.
The other universal criterion of beauty is youthfulness and the absence of wrinkles on the forehead.
Everything ages, even our foreheads! Our skin wrinkles, our muscles thin and even our bones shrink. As a result, our foreheads feel the effects of time. As time goes by, the skin on the forehead relaxes, wrinkles and folds. Occasionally, it can also develop small excrescences and age spots. The muscles beneath our foreheads also age. They become thinner, which progressively reduces the forehead's curvature. As a result, the forehead loosens a little and its height increases.
Not to mention that we wrinkle our foreheads and eyebrows every time we see or hear wrong. In other words, over time, the forehead increases in mobility, even if some people are originally more expressive than others, raising their eyebrows or furrowing their brow at every utterance.
Botox rests and relaxes all these expressions and makes the forehead a little less mobile and expressive.
Thanks to its relaxing properties, botulinum toxin relaxes the muscles whose contraction is responsible for certain wrinkles and fine lines: forehead wrinkles, crow's feet and frown lines (glabellar or lion's wrinkle) can be treated with botulinum toxin.
Botulinum toxin injections have been used in aesthetic medicine for over a decade.
Depending on the indications, botulinum toxin injections can be performed in the areas concerned. No anesthesia is required.
Slight redness or swelling may appear in the treated areas for a few minutes, rarely more than half an hour. You can resume your daily activities immediately after the procedure, but should avoid any strenuous physical exertion.
The result of the injection is visible between the 3rd and 5th day, and the full result after 2 weeks.
As with any aesthetic medical procedure, the result is not definitive. Further injections are necessary (on average 2 per year).
Contraindications:
- Hypersensitivity to botulinum toxin
- Recent use (within 10 days of surgery) of aspirin or corticosteroids
- Pregnancy or breast-feeding
- Inflammatory skin diseases that must be treated prior to treatment.
Botox acts on the muscular balance of the face. Using precise points adapted to your anatomy, Botox relaxes certain muscles, opening up your eyes for a more serene appearance. With the right concentration and quantity, your expressions are preserved.
While we used to see faces that were too rigid, injection techniques have improved considerably. Today, we no longer have to sacrifice facial expression to make wrinkles disappear.
Injected at strategic points, botulinum toxin repositions the eyebrow and opens up the eyes by lightening a heavy upper eyelid. In the glabella, Botox eliminates frown lines, which can give the impression of being anxious or worried.
ANATOMY
FRONTALIS MUSCLE
It is an even, thin, quadrilateral muscle that inserts anteriorly into the brow and inter-brow region. Its fibers cross those of the orbicularis oculi and procerus muscles, as well as those of the distal corrugator muscles.
Its posterior edge attaches to the galea and its anterior edge to the orbital rim. Its fibers are vertically oriented.
Together with the digastric occipito-frontal muscle, it helps raise the eyebrow. Its contraction is responsible for the appearance of horizontal forehead wrinkles.
For a long time, during brow lifts, we tried to modify the shape and position of the eyebrow by traction with vertical vectors. The results were disappointing, unnatural and not very long-lasting. Later, muscle surgery became indispensable, with myectomy and myotomy. Today, botulinum toxin has revolutionized treatment. It acts on the orbitofrontal muscle balance, modifying the position and shape of the eyebrow. Only ptosis of the outer 1/3 of the eyebrow remains accessible to surgical treatment, thanks to temporal lifts that allow temporo-orbital redraping and elevation of the eyebrow ridge.
