Generally 20 units is a standard amount that works well for most people.

Thank you for your question.

For the 11 lines (glabellar area), 20 units is a pretty standard dose. For those with stronger muscles, it can go up to 25 units, and the reverse would apply for those with weaker movement or with history of multiple botox procedures. 

I have seen individual cases where one specific treatment of Botox "doesn't take" and there is minimal to no effect. Whether this is due to injection technique or inactive botox from the bottle, it is unknown. Some people are actually somewhat resistant to the effects. But again, these are all rarer reasons for a treatment that doesn't work.

Try your treatment one more time - again, 20 units is pretty standard and should work. It may be the case that you need slightly more, but rarely more than 25 units. I really hope that you get a great treatment that works well for you.

Good luck!

The average number of Botox units I use to treat the glabellar frown lines (the so-called "11's") is 20 units.  For most patients, the effects begin to show within 48-72 hours.  Some patients may get the same results with less Botox, other patients require slightly more.

I caution patients to wait at least 3-4 days before judging the outcome.  If the level of paralysis or areas of paralysis are insufficient at that point, I will re-examine the patient to see whether a "touch-up" injection will be beneficial, but I usually wouldn't administer an additional dose of the Botox until one week after the first dose.

Botox injection should be performed by an experienced practioner in an ethical and professional manner.  A frank discussion regarding risks, benefits, and intended number of units should be discussed between patient and physician. In general, twenty to thirty units should be injected into the glabella, upper nose, and mid forehead.

Generally, most patients benefit from a standard dose of 20 units of Botox to treat frown lines. The reason being, to create the frown, there are several muscles involved that need to be dosed. To use less than ideal will result in little or no effect which would definitely be wasted time and money combined with disappointment.

As mentioned by the panel members, most people will not begin to see the effects for 24 to 48 hours. Thereafter, it may take up to 14 days to see the full benefits. It would appear that your practitioner did not take the time to provide you with correct information and patient education for your expected outcomes.
