Dear Sugardonut, The amount of BOTOX is important for the overall effect and the length of effect. Also, There are 2 toxins available now- Dysport and BOTOX Cosmetic- they require different amounts of toxin for effect.
Also, very important is the agent used to dilute the BOTOX- "NON- preserved saline" has as little alcohol in it and it is much les painful for the injection of the BOTOX.
Finally, the needles need to be fresh- i use a different needle for each site- a BD 31 gauge needle- very sharp so it hurts less.
With Warm Regards,
Trevor M Born MD
