• How long will the effects of the Botox® last?

The duration of effect depends on several factors, such as the type of preparation used and its concentration, and the dosage injected.
 
The aim is to achieve the right balance between a higher dose for a pronounced, long-lasting effect and a lower dose to lessen the risk of side effects or complications.
 
The amount of muscle mass and muscle tone, the skin’s thickness, the activity of the area and a person’s gender and ethnicity also influence the final result and the length of time of effect.
  
The effects of the Botox® generally begin to wear off around 4 months after the initial treatment, and some clinical studies have shown that over time, treatments may be needed less frequently, as the habit of using those muscles becomes broken.
 
Should you stop having Botox® treatments, the lines and wrinkles will gradually return to their pre-treatment condition.
