Repeat Botox Dose After 10 Days Without Effect?

Results from Botox treatment for dynamic lines depends on all of the three above criteria. Botox can be used very effectively in lower doses in many patients if the treating physician has years of experience and isn't just following a set "grid" that is often taught in one to two day crash courses. Also, Botox is made in "batches" so sometimes one bottle is weaker than the rest. Botox is placed into specific muscles based on teaching, anatomy and experience, but isn't always in the "belly" of the muscle, so re-treatment may be necessary.
Rarely, a few patients may have Botox "resistance." So, all of these conditions should be taken into account for each and every Botox treatment, especially repeat treatment.

Botox begins to work a few days after your treatment. The majority of effects are seen at one week, but small changes can continue for 2. I encourage my patients wanting additional units to wait a minimum of 2 weeks to add, as we want to avoid overtreating. If your Botox has had no change in 10 days, there are many possible reasons for this. You may be one of the few non-responders. The botox used may have lost its potency depending on the storage procedures prior to and after reconstitution. Or you may need a much stronger dose than you were originally given. The amount to try after 2 weeks has passed depends on the reason for the botox not working. Good luck!
