How long after a brow lift can I get Botox to raise the outer corner of my eyebrows more?

You can proceed with Botox injections at any time. Without being able to see you in person, it's hard to say just how many units you might need. It's important to remember that Botox is a temporary fix.

Botox to raise the brow works by relaxing the muscles that pull the tail of the brow down (depressors). Some people don't have strong "depressors" so won't get much of a lift. Plus the  results aren't always reproducible. If it does work you should see results in a week.

Surgery to raise the brow can be by endoscopic browlift or sub-cutaneous (skin) brow lift. The choice depends on your anatomy and what you want to look like after.
