Botox and Semi Permanent Eyebrows?

     I would wait at least two weeks to see the full effects of Botox before getting a retouch of a tattoo for best results.

Tattoo first as the arch you create with this will determine how the rest of the forehead and the midbrow will be treated with Botox.   Tattooing after Botox is using a permanent dye to adjust for temporary Botox effect and puts you at risk for long term issues if you ever stop using Botox.

Your Botox treatment doesn't typically kick in overnight but, I would wait until the treatment wears off if you are having a "chemical brow lift" as brow position changes.
