Botulinum toxin (Botox)

Botulinum toxin (commercial name Botox) is a preparation resulting from a toxin produced by the Clostridium botulinum bacterium. It acts by blocking neuromuscular transmission, thereby relaxing the action of the muscles. It has many applications in medicine today, including facial rejuvenation without surgery.

As it relaxes the facial muscles, certain wrinkles disappear or smooth out. Botulinum toxin works particularly well on three areas: between the eyebrows, the forehead and on crow's feet.

After being injected, botulinum toxin takes about three to five days to achieve its full effect. This injection is painless and does not require any post-operative treatment. One week after the injection the result is evaluated and, if deemed necessary, the treatment can be touched up. The effect of botulinum toxin is always temporary and lasts between three and six months.

Any possible complications resulting from the treatment are also always temporary. These complications are extremely rare provided the injection technique is sound.

Fillers: hyaluronic acid 

Over the years, the facial tissue usually loses volume with the consequent appearance of folds and lines. Today treatments are available to replace this lost volume by injecting natural fillers such as hyaluronic acid. These treatments are carried out during the consultation and recovery is almost immediate. Hyaluronic acid can be used on most areas of the face, such as between the eyebrows, on nasolabial folds, the jaw, lips and cheeks.

There is another area where the application of hyaluronic acid is particularly useful: on bags under the eyes. Those patients with prominent creases under the eyes are good candidates for this treatment. The application of hyaluronic acid effectively fills these lines under the eyes, providing a totally natural appearance.

These treatments are not permanent and usually last between six and eighteen months, depending on the product used. Should the treatment not be satisfactory for the patient, the hyaluronic acid can be dissolved in just a few hours by applying hyaluronidase.
