Spock eyebrows. They’re more common than you think, and if you’re considering getting Botox in your forehead, it’s important to be aware of. Spock brows are a side effect of Botox that causes your eyebrows to arch unnaturally high, and while it’s typically caused by novice injectors, even the most experienced injectors can make a mistake. And that’s why we spoke with board-certified dermatologist Aanand Geria, MD, to bring you the facts. Keep reading to learn why Spock brow happens and how it can be prevented and corrected.

What are Spock eyebrows after Botox?

According to board-certified dermatologist Aanand Geria, MD, Spock brows are when the eyebrows are lifted too high after Botox treatment, resulting in an unnatural looking arch. It happens when Botox is injected unevenly. Spock brow can be reversed with a follow-up injection, or it will naturally fade over 3-4 months.

What causes a Spock brow?

Spock brow is caused by uneven Botox in the forehead and/or brow. If a Botox forehead or eyebrow treatment is done incorrectly, it can result in negative effects, such as a Spock brow. Injecting the treatment into the upper face muscles is a delicate process, which is why Dr. Geria notes that Spock brow is “more common in novice injectors.”^{[4]

Expert Interview} If Botox is injected into the procerus muscle (the muscle that runs up the middle of the forehead) and the corrugator muscle (the muscle along the top of the brow) but not the frontalis muscle (the muscle that raises the eyebrows), the frontalis pulls up and out, creating an arched brow effect.^{[5]

How long does Spock brow last?

Spock brow goes away on its own in 3 to 4 months. While it takes time, Spock brow will go away without additional treatments. Botox wears off after a few months, which is why follow-up injections are recommended every 3 to 4 months to maintain results. If you have a Spock eyebrow, it will slowly start to look less intense over 3 to 4 months as the Botox gradually wears off.^{[8]

Expert Interview} However, you must be patient. It can take the chemicals in Botox up to 2 weeks to fully take effect, even if Spock brow is noticeable right away.
