The dose is measured in units and depends on the area and the strength of the muscles: men's muscles are stronger and require more units, and the glabella is "hungrier" than the forehead. That is why the correct approach is a calculation tailored to your specific expressions, rather than a "fixed price per area, sight unseen".
- The glabella, forehead and crow's feet are the most common areas.
- The effect develops over 3–7 days, reaching its final result by day 14.
- It lasts on average 3–6 months, after which the muscle gradually recovers.
