Overview
Botulinum toxin injections, commonly referred to as Botox® in everyday language, are among the most widely used treatments in cosmetic medicine for correcting facial expression lines.
Over time, certain facial muscles contract repeatedly. These contractions gradually lead to the appearance of dynamic wrinkles, particularly on the forehead, between the eyebrows (frown lines), and around the eyes.
Botulinum toxin works by temporarily relaxing the muscles responsible for these wrinkles, which smooths the skin and gives the face a more rested appearance.
The goal of the treatment is not to freeze facial expressions, but to reduce the intensity of muscle contractions in order to preserve the face’s natural mobility.
Dr. Alexandre Vairinho administers botulinum toxin injections using a personalized, step-by-step approach, taking into account each patient’s unique facial structure and expressions.
Explanation of the technique
Botulinum toxin injections involve injecting very small amounts of the product into certain facial muscles to reduce their contraction.
Botulinum toxin works by temporarily blocking nerve signals between the nerve and the muscle. The muscle then gradually relaxes, which helps reduce expression lines and prevent them from worsening.
The treatment is performed with precision to preserve the facial muscle balance and achieve a natural-looking result.
Botulinum toxin injections are primarily used to treat dynamic facial wrinkles, that is, wrinkles caused by muscle movement.
The most commonly treated areas are:
- forehead wrinkles
- frown lines (between the eyebrows)
- crow's feet at the corners of the eyes
Depending on the situation, botulinum toxin can also be used to:
- lift the tail of the eyebrow slightly
- smooth out certain wrinkles in the lower face
- improve the balance of the expressions
The areas to be treated are determined during the consultation to ensure a harmonious and natural-looking result.
Consultation Process
Treatment with botulinum toxin injections begins with a medical consultation to assess your face and determine whether the treatment is appropriate for you.
During this consultation, a clinical examination is performed to assess expression lines, facial muscle dynamics, and the overall harmony of the facial features. Analysis of facial expressions helps identify areas that could benefit from treatment.
This step also provides an opportunity to discuss your expectations and set realistic goals. You will receive medical information, and a personalized quote will be prepared. Medical photographs may be taken to facilitate follow-up and evaluation of the results.
Botulinum toxin injections are administered at the doctor's office. The procedure is quick and usually takes 10 to 15 minutes.
The product is injected using very fine needles into the targeted muscles responsible for expression lines. The procedure is generally not very painful and does not require anesthesia.
Post-injection effects and expected results
The aftereffects are generally mild and allow for a quick return to daily activities.
After the injection, the following may occur:
- mild redness at the injection site
- a small localized swelling
- minor bruises in some cases
These symptoms are usually temporary and go away quickly.
However, certain precautions are recommended in the hours and days following the injection:
- Avoid exercise for 24 hours
- Avoid applying pressure to the injection site for about 6 hours (for example, by wearing a helmet)
- Avoid saunas and steam rooms for a week
- Avoid prolonged sun exposure during the first week, as it may reduce the treatment’s effectiveness
These recommendations help optimize the product's performance and reach.
The effects of botulinum toxin appear gradually in the days following the injection.
The first results are usually visible within 3 to 5 days, with optimal results observed after about 10 to 15 days.
In particular, the treatment allows for:
- smoothing of expression lines
- a more rested look
- a reduction in forehead and frown lines
- an improvement in facial harmony
- a natural look without making your face look stiff
The effects of botulinum toxin are temporary and generally last between 4 and 6 months.
Follow-up sessions may be offered to help maintain the results over time.
