What muscle in the forehead is targeted for botox injections?

The muscle that is commonly targeted for Botox injections in the forehead is the corrugator muscle. This muscle is responsible for creating the furrowed brows or frown lines often seen between the eyebrows. Botox is injected into this muscle to temporarily paralyze it, which smooths out the lines and gives a more relaxed appearance.

While the frontalis muscle does play a significant role in forehead movement and can contribute to horizontal lines on the forehead when raised, it is primarily the corrugator that is focused on for treating the vertical lines in the glabellar region (the area between the eyebrows).

Additionally, the temporalis muscle is involved in jaw movement and is not relevant in this context, while the orbicularis oris muscle, which encircles the mouth, is unrelated to forehead treatment. Hence, targeting the corrugator muscle is essential for addressing frown lines effectively through Botox injections.
