With the stress of school, work, and everything else that’s going on in your life, you might be frowning a lot more than you are laughing. So those brow furrow marks can appear a lot sooner than you’d like. But don’t worry, you don’t need Botox just yet.

Botox injects a neurotoxin protein into the muscle to block its nerve impulses. This means that when you make a certain facial expression (say, a frown), the area won’t contract to create a furrowed look, says Begoun. But there’s also the chance that it’ll leave your face expressionless or unable to move — you don’t want to risk that, do you?

Plus, Botox can cost between $300 to $400 for areas that require a few injections (like around the eyes). For a larger area like the forehead, it can cost up to $800. That’s like, 10 years’ worth of products.
