Will botox work in area where i used renova (tretinoin)?

I think so: There are no interactions that i can find between the two drugs. As always, make sure any of your physicians are aware of all the drugs that you are using!

Yes: Yes, there is no interaction between the two.

Of course: Renova (tretinoin) only penetrates into the superficial dermis. Botox is injected into the subcutaneous tissues or muscle which are much deeper. There is no interference whatsoever.

Botox and Renova (tretinoin): Yes, Botox will still work. Renova (tretinoin) and Botox work differently, but I am sure that with both your wrinkles and fine lines will be significantly less pronounced.

Yes: Yes, this should not be a problem.

Yes: Yes, in some areas. In areas where wrinkles not due to muscular contraction - no effect. See facial plastic surgeon for best result.
