Using a dermaroller one week after your Botox treatment should not impact your results. I would however recommend seeing a professional for microneedling treatments. It is important that the tool is used correctly to avoid any unintended damage to the skin.
You may be starting to see and feel some of the effects of the Botox, but it will take two weeks for you to see the final results. If after that time you still have concerns, return to your injector for an evaluation.
The final results from your Botox treatment can be seen 14 days after injection. If you still have concerns at that time, return to your injector for an evaluation. Sometimes a small touch up of Botox is needed to lessen the "Spock" effect.
