Botox in the face: an expressive and rejuvenated face
New York

Botox® is the registered trademark of botulinum toxin A, the cause of botulism, a disease caused by Clostridium botulinum.

This toxin was isolated as early as 1946, but it was in the 1970s that Dr. Jean Carruthers, an ophthalmologist, used it to correct strabismus related to hyper-contraction of muscles. The result worked perfectly but he noticed a second effect: his patients were getting younger. This is how Botox face was developed in aesthetic medicine, making botulinum toxin the first drug in the world recognized as an anti-wrinkle treatment in 2002.

Wrinkles are one of the most visible signs of facial aging. Their occurrence depends on two main causes:

Static wrinkles appear because the tissues under the epidermis lose their volume, resulting in a hollow (naso-labial fold) where the epidermis "falls off";

-Expression wrinkles appear because the skin and the envelope of the skin muscles (SMAS superficial musculo aponeurotic system) lose their elasticity and do not regain their shape after contraction, leaving a persistent fold.

Botulinum toxin works by binding to acetylcholine receptors, a mediator in the synapse that gives the muscle the command to contract sent by the nerve.

Botox is a neurotoxin that paralyzes the muscle by relaxing it and preventing it from contracting: this is known as the muscle relaxant effect. This muscular slackening leads to the skin one and the wrinkle fades away.

Botox will therefore not have this smoothing anti-wrinkle action on static wrinkles, it only targets the muscles of the skin responsible for our expressions and therefore expression lines.

The purpose of a Botox facial injection is to erase the negative effects of a muscle hypercontraction on an area of the face, whether these abnormalities are congenital or acquired.

Botulinum toxin injection for facial rejuvenation

Botox injections are the perfect solution for erasing dynamic wrinkles on the upper face (expression lines), which are visible very prematurely from the age of 40.

A Botox injection makes it possible to remove :

• Crow's feet wrinkles (corner creases), to rejuvenate your eyes.
• The frown line between the eyebrows or frown line, which gives you a hard look;
• The horizontal forehead wrinkles, which give you a tired or worried look.

Not only is the face refreshed and looks younger, but the Botox facial injection erases all your negative expressions (severity, fatigue, sadness ...).

Contours reshaping with botox injections

Botulinum toxin is used in facial remodeling to correct hypercontraction of skin or deep muscles:

• Correction of a jaw that is too square, if it is due to excessive contraction of the masseter muscles. The medical diagnosis must therefore be precise. It is the same principle to treat bruxism.
• Correction of a nose (medical rhinoplasty) that is too long if it is the result of hyper-contraction of the nasal muscle causing the nose to lengthen and point downwards when the patient smiles.

It is a traditional injection procedure, performed in the medical block at Clinique des Champs Elysées New York.

According to the desired goals, the practitioner will determine the muscle to target, the entry point and the appropriate dosage.

He chooses the right dose of botulinum toxin to achieve a natural effect, without freezing your skin muscles or your expressions.

The result becomes noticeable little by little over a few days, with a stabilized effect around D10/J15.

The before and after of a Botox injection is indisputable, with a younger, more harmonious and cheerful face.

However, the result is temporary because the botulinum toxin is broken down in four to six months naturally. This action is often a little shorter on the first injection, but it becomes optimal after the second injection.
