How Often Should One One Use Botox if You Are 34 and a Smoker?

Botox usually lasts 3-4 months in between treatments.  I always say its once a season for Botox.  There is some vartiability among patients but this is a general rule. 

If too much Botox is injected around your mouth, you may not be able to speak or eat properly, so only a small amount is injected.  Puckering with smoking will wear it off more quickly, so the lasting effect of the Botox will vary.

Smoking should not affect the efficacy of botox.  Most patients get 3 months of relaxation with Botox.  Some last longer.   If it wears off sooner, you may need a stronger dose at your next treatment.
