Hi, Looks like you want the opposite of what mostly all others are seeking; a lower brow rather than your naturally higher one. Some botox, or other botulinum toxin injected above your brow will relax the muscle that pulls it up and will thus lower the brow. This would likely last around 3 months, but in some cases can also have some longer term effects, as it will continuously weaken the muscle. With age, your brows will naturally drop as well, so it might not be a great idea to have surgery and promote those changes. Even if you decide to go the surgical route, trying botox once or twice is a great idea before committing to permanent changes. Good luck.
