Why do my brows go up in the first week after botox before drooping some?

It takes 1-2 weeks for final results with Botox. Botox results will resolve in 3-4 months. See an expert. Best, Dr. emer

Hello, your brows get a lift from the Botox injections because relaxing the muscle in the glabella (corrugators) that help us frown or furrow the brows will relax and elongate the muscle, allowing for the brow to lift some. It is usually subtle, 2 mm or so but creates a nice brow lift. You can ask your injector to inject this area, especially towards the outer 1/3 of your brow. 

Hello and thank your for your question. It can take 1-2 weeks for your final results with Botox. A small amount of Botox in the medial depressor supercilii muscle as well as the tail end of the eyebrow  (orbicularis oculi) can to help give you a little bit of a lift.  Best of luck!

I appreciate your question.My guess is the muscles pulling the eyebrow down relaxed first after your Botox injection leading to the frontalis muscle pulling the eyebrows up! Then as the Botox took effect in the frontalis and the muscle relaxed, the eyebrows dropped. Always follow up with your injector/physician two weeks after the injection.Good luck. Dr. ALDO 

It can take a good 7-10 days for botox to work, so that during that first week or so things might move as bit funny.

The group of muscles that pull down the eyebrow are very thin and very weak and they respond to Botox first. That is the reason for the spike of the eyebrow in the tail especially. Good luck from New York City

It's hard to give you a complete answer without seeing a photo or evaluating you in person. Yes, neuromodulators like Botox and Dysport can be used to raise the eyebrows. I recommend you discuss this with your injector in person.
