Leading drug in aesthetic medicine, Botox ® is the registered trademark of botulinum toxin A, becoming almost a common name. A Botox forehead injection is intended to erase forehead wrinkles by smoothing the skin without surgery. The skill of the aesthetic doctor is to respect the indications, through a flawless technical process that smoothes the wrinkles but not the expressions, for a natural looking result.
How does botox injection works on the forhead?
The skin muscles, also called skincier muscles, work on the face to express our emotions. They are located between the skin and the bony reliefs, and are wrapped in a connective tunic (superficial musculo aponeurotic system or SMAS).
This fascia, like the skin, will lose its elasticity and tonicity with age.
The frontal muscle extends from the base of the skull (occiput) to the orbits (occipito-frontal muscle). Since it is a digastric muscle, the anterior part, which extends from the anterior hairline to the eyebrows and orbicular muscles, is mainly referred to as the frontal muscle.
This temporal muscle is involved in the lifting of the eyebrows, following an influx of the temporal nerve from the facial motor nerve.
Tissue aging affects the dermis of the skin as much as the fascia of SMAS. The loss of elasticity means that a contraction of the frontal muscle results in a persistent fold because the tissues are no longer flexible and elastic enough. These horizontal wrinkles or frontal wrinkles belong to dynamic wrinkles (excessive muscle contraction) or expression wrinkles.
Forehead wrinkles give your face a worried, tired or harsh appearance, which can negatively affect your socio-professional or personal life.
A botulinum toxin of the forehead will suppress this contraction of the muscle fibers. Botulinum toxin A inhibits the action of the neurotransmitter of the synapse, between the nerve and the muscle, by competitive inhibition. As the frontal muscle is no longer stimulated, its fibers no longer contract and they relax (myo-relaxing effect also called flaccid paralysis). Muscle and skin relax, returning to a smooth appearance.
Indications: rejuvenate with forehead Botox ® injection
Botox® injection is the solution of choice to correct dynamic forehead wrinkles that appear on the forehead because the forehead muscle is too contracted. The goal may be to remove negative emotions from the upper face (severity, anxiety, fatigue...) or a simply a rejuvenating effect for aesthetic purposes.
For less pronounced forehead wrinkles combined with a loss of volume, the practitioner may consider an injection of hyaluronic acid. This filling product will recreate volume by plumping up the skin, resulting in a small lifting action on the skin.
Follow a forehead botox injection
This injection session takes place in a sterile medical block at Clinique des Champs-Élysées in New York. It is quick (10 to 20 minutes) and the patient returnsto daily activities without social eviction as soon as the session is over.
To erase forehead wrinkles, your doctor will be very meticulous in identifying the point of entry of the injection.
He will target the upper region of the muscle by performing the intramuscular injection 3 cm from the bony edge of the eye socket, otherwise there is a risk of eyebrow ptosis.
He often performs between three and five injection points, to offer an even result, and if necessary, he takes into account any initial asymmetry of the eyebrows.
Forehead Botox injection results
The effect is never immediate. Botulinum toxin gradually blocks the acetylcholine receptors and the frontal muscles progressively relax.
In 4 to 10 days on average, your forehead skin regains its youthfulness with a smooth appearance. You look younger, more rested, less worried, more toned with an effect that will last up to six months.
It is rare for the eyebrow to become too lifted, following a hyper contraction of the external frontal muscle. This is known as the Mephisto effect. It is easy to correct with a touch-up after the third week.
