The effect of Botox is temporary
The function of the muscles returns slowly after 4 to 6 months and by that time repeating the treatment will be a possibility.
In the ideal scenario there will be the “forgotten-how-to effect”, which means that because you were unable to frown temporarily, you will have forgotten how to do it and the frown lines will soften permanently.
Dilution of Botox and duration
Many healthcare instances offer Botox injections, often against very competitive prices. The explanation is that Botox can be diluted, the higher the concentration, the longer the effect.
The correct indication
It is important that injections are given based on the correct indication. For example, if you have wrinkles and you look worried or angry due to drooping of your eyebrows or eyelids, then Botox injections have no effect. Botox injections could even worsen the problem. Individual advice in advance is therefore recommended.
Sporadically slight bruising can occur at the locations of the injections. Occasionally with the injections in the frown lines the fluid can run to the eyelid and cause a slightly drooping eyelid. This is a harmless but irritating complication that will disappear within 2 weeks.
Botox cannot be used on people who suffer from muscular diseases or muscle weakness.
