Which muscle of the forehead is Botox commonly injected into?

The muscle of the forehead that is most commonly associated with Botox injections is the frontalis. The frontalis muscle is responsible for raising the eyebrows and creating forehead wrinkles. When Botox is injected into this muscle, it relaxes the muscle, which helps to reduce the appearance of dynamic wrinkles, such as horizontal lines across the forehead.

Botox works by blocking the signals from the nerves to the muscles, preventing them from contracting. This results in a smoother appearance of the skin in that area. While other muscles, like the corrugators (which create vertical lines between the eyebrows), are relevant in the context of facial aesthetics, the primary focus for forehead wrinkles is the frontalis muscle.

Understanding the specific functionality of these muscles is critical in esthetics, as it guides the practitioner in achieving the desired cosmetic outcomes effectively and safely.
