Botox®

Botulinum toxin injections are the treatment of choice for correcting expression lines. Dr Hayot has been performing Botox® injections for over 25 years.

The different areas for Botox injections

Botulinum toxin injections are commonly used to correct and soften expression lines such as frown lines, crow’s feet, nasolabial folds and perioral lines.

What is Botox®?

Botulinum toxin was originally used in ophthalmology to relieve patients suffering from blepharospasm, an involuntary contraction of the eyelid muscles. The molecule has an interesting property: it inhibits muscle mobility and activity.

Today that property is used in aesthetic medicine to reduce facial expression lines, which are the result of repeated, involuntary muscle contractions. Botox® effectively corrects forehead wrinkles and crow’s feet around the eyes, as well as wrinkles of the lips, chin and neck.

Why treat expression lines with Botox®?

Expression lines are among the first signs of ageing. The expressions we make most often throughout our lives eventually form visible breaks in the skin.

These are known as dynamic wrinkles, because they are caused by muscular activity in the face. With age they are accentuated by slackening skin, and soon become visible at rest.

Because botulinum toxin relaxes muscular overactivity, it is particularly indicated for the treatment of expression lines.

Contraindications to Botox® injection

Botulinum toxin injections are contraindicated in the following cases:

  • Pregnancy or breastfeeding
  • Neuromuscular disorders
  • Anticoagulant treatment
  • Active infection or inflammation of the area to be treated
  • Intolerance or allergy to any of the product’s components

Botox® injections for wrinkles

Botulinum toxin is the treatment of choice for certain wrinkles, in particular expression lines: horizontal forehead wrinkles, crow’s feet, frown lines and perioral wrinkles.

Botox® injection for the forehead

Highly visible horizontal forehead wrinkles are a frequent reason for consultation in aesthetic medicine. To reduce the activity of the frontalis muscle without freezing the patient’s face, Dr Hayot has developed the micro-Botox technique, which involves injecting the product not into the muscle but into the superficial layers of the skin. After your session, you will need to wait around 8 days to see the optimal result.

Botox® injection for the jaw

Botulinum toxin can also be used to correct an excessively square jaw. The request often comes from women who are self-conscious about a thick masseter, which gives the face a masculine look. Injections are then made into this muscle to reduce its prominence and refine the angle of the jaw.

Botox for frown lines

Frown lines, between the eyebrows, age the face and give it a severe appearance. Injecting botulinum toxin into this area softens the expression by reducing muscle contractions, giving the face a much-appreciated youthful look.

After-effects of Botox® facial injections

After Botox® injections, some transient side effects may occur. These are mainly redness, bruising at the injection sites and sometimes slight oedema, or swelling. These symptoms are nothing to worry about: they disappear within a few hours, or a few days at most.

Results after Botox® injections

Injections of botulinum toxin give excellent results in the treatment of expression lines. Dr Hayot always ensures that the result is natural and harmonious, and avoids over-correction.

The result is stable approximately 6 months after the first session. After that, if the patient feels the need, further injections can be performed.

The price of botulinum toxin injections with Dr Hayot

The cost of Botox® injections depends on the area treated and on the quantity of product required.

Introduction

Botulinum toxin injections are the treatment of choice for correcting expression lines. Dr Hayot has been performing Botox® injections for over 25 years.

The different areas for Botox injections

Botulinum toxin injections are commonly used to correct and soften expression lines such as frown lines, crow’s feet, nasolabial folds and perioral lines. Thanks to its muscle-relaxing effect, Botox reduces the unsightly wrinkles and folds visible on the face with age. Botox smoothes the crease that forms between the eyebrows, known as the “frown line”. The masseter, the jaw muscle, is sometimes too prominent. Its volume can be reduced by Botox injection. Botox is a particularly effective solution for correcting forehead wrinkles.
