Hello, thank you for your question. You should be ok to get both on the same week, schedule a consultation to see a local expert injector with extensive experience and training to ensure optimal results and safety.
there is no way to know the answer to this but its pretty safe to say that it shouldn't make a difference. botox really doesn't get absorbed. and anyone using botox should be dermarolling at the same time to get the most improvement at home with collagen production (see link). Best, Dr. Emer.
