Are botox injections long-lasting?

What are botox injections in aesthetic medicine?
Botulinum toxin is a neurotoxin that occurs naturally in the body. It was originally used mainly in ophthalmology, to calm involuntary contractions of the eyelid muscles.
Today, botox is mainly used in injections to correct expression lines, the first signs of the passing of time. These wrinkles are the result of repeated muscle contractions of the face. Botulinum toxin inhibits the mobility and activity of the muscle by blocking the neurotransmitter. The muscle no longer receives a signal and relaxes.
Botox injections are particularly effective in reducing or erasing these dynamic wrinkles and in correcting defects linked to muscle contraction.
On the forehead
To correct horizontal forehead wrinkles, the product is injected into the superficial layers of the skin rather than into the muscle. This technique, known as micro-botox, gives particularly natural results.
The jaw area
To correct a square jaw, botox is injected into the masseter muscle. The size of the masseter is reduced, which refines the angle of the jaw.
Between the eyebrows
Frown lines can be reduced easily with botulinum toxin injections. Muscle contractions are reduced.
Botox injections have become an essential part of anti-ageing medicine. They can also be used to treat crow’s feet, wrinkles around the mouth, chin wrinkles and neck bands. They can also correct poor facial symmetry, excessive sweating, a square jaw and bruxism.
Botox injections usually take place at the doctor’s practice. Botox has the advantage of requiring no anaesthetic, and it is resorbed naturally after a few months.
Why might your aesthetic physician recommend botox?
Botox is mainly indicated for dynamic wrinkles, that is, expression lines. It rejuvenates the face easily and without surgery. This product has many advantages:
- Botox is a particularly simple solution: the injections are performed without anaesthetic and take about ten minutes. The procedure is painless and leaves no scars.
- The first result is immediate: only a few minutes after the injection, the facial muscles relax. You then need to wait around 5 days to see the product’s optimal result.
- A cure for youth, and for confidence: rejuvenating the face so easily has a clear effect on the well-being of patients, who feel better in their own bodies.
- Non-permanent results: after a few months, the botox is resorbed naturally.
Are the results of botox injections permanent?
The results of botox injections are not permanent. They are stable for approximately 4 to 6 months after the first injection session, before the product is gradually resorbed. Further injections are needed to maintain the optimal result. After the second injection session, the results last longer: 6 to 8 months.
