how far(in milimeter)can 1unit botox spread from the site of injection? i had botox injected on my face and it worked on the muscle under the spot where doctor marked and injected but the point where i really wanted to fix didnt change. i asked him to inject on that point but he told me to wait. but if botox only effect on the point/site where it injected, theres no point of waiting right? or will it also spread to some range and will effect on the point i want because it is on the same muscle?
