The main cause of forehead wrinkles is facial expressions. Facial expressions are the result of tensing certain muscle groups, for example when concentrating or smiling. When concentrating, the muscle groups that run vertically down the forehead are tensed. This creates horizontal lines that are always visible when the eyebrows are raised. Vertical wrinkles that run from the nasal root to the forehead occur when the eyebrows are contracted in annoyance. The same horizontal muscle groups are also activated while squinting the eyes because of bright light.
Treating forehead wrinkles with Botox directly tackles the cause of the problem. Botulinum toxin is a neurotoxin that inhibits the communication between the nerve cells and the muscles cells. Botox prevents the muscle cells from receiving the signal necessary for the muscles to contract. This is why the botulinum toxin is injected into specific sites around the forehead wrinkles. When the right injection sites and the correct dose are selected, the muscles involved in facial expressions are not completely paralysed. They simply work at a lower level of tension. Therefore, only the deepest forehead wrinkles are prevented.
Botox is gradually broken down by the metabolism. The speed at which this happens is different for each person. The forehead wrinkles generally disappear for a period of three to six months when treated with Botox. Since the effect reduces slowly, the reappearance of forehead wrinkles looks very natural. Further injections can be administered once the first signs of forehead wrinkles caused by expression muscles can be seen.
In preparation for the treatment of forehead wrinkles with Botox, the cosmetic surgeon must briefly examine the patient. The treatment does not require full or local anaesthesia, as only a small pinch can be felt. The patient also does not require rest after the Botox treatment. Normal work and exercise as well as social activities can be resumed immediately. In rare cases, minor swelling in the injection site can appear. It disappears very quickly if the area is cooled. The injections themselves only take a few minutes.
When the Botox injections are performed by an experienced cosmetic surgeon, there are no health risks. Even though Botox treatments have now become socially acceptable and even ‘Botox parties’ are available, it is still a very potent medication that should only be used and dosed by doctors. If too much Botox is injected, a mask-like appearance can occur that (depending on the extent of the overdose) will subside after a few days or weeks due to the natural breakdown by the metabolism.
