Botox for the forehead – get rid of wrinkles with botulinum toxin
Botox for the forehead is one of the most common aesthetic botulinum toxin treatments. Botox treatment can reduce and correct horizontal forehead wrinkles. This is achieved by reducing the contractile force of the forehead muscles.
Forehead wrinkles form when the frontalis muscle repeatedly raises the eyebrows and contracts the skin on the forehead.
Botulinum toxin reduces the nerve-mediated activation of the muscle, causing the forehead to smooth out and the wrinkles to diminish.
The purpose of Botox treatment is not to make the face expressionless. The treatment aims to reduce forehead wrinkles while preserving the client’s natural facial expressions.
What do the results of a Botox treatment for the forehead look like?
How do forehead wrinkles form?
Forehead wrinkles are directly linked to the activity of the facial muscles. The frontalis muscle, shown in the anatomical diagram, is responsible for raising the eyebrows. At the same time, it creates horizontal wrinkles on the forehead. In Botox treatment, the activity of the frontalis muscle is reduced with small injections. As the muscle relaxes, the skin also smooths out. However, facial expressions remain natural.
Where on the forehead is Botox injected?
In forehead Botox treatment, injections are administered into the forehead muscle (m. frontalis), among other areas. The injection sites are always planned on an individual basis, taking into account the patient’s facial muscle activity. Careful planning helps smooth out forehead lines without compromising the face’s natural appearance.
The treatment takes into account, for example
- strength of the forehead muscle
- the position of the eyebrows
- shape of the eyelids
- skin elasticity
- the patient's facial expressions
Injections placed too low can weaken the frontalis muscle too much and cause the eyebrows to droop. For this reason, injection sites are carefully planned based on each individual’s anatomy.
A Surgeon's Perspective
Botox treatments in the facial area require a thorough understanding of anatomy. In the forehead area, injections are administered into the frontalis muscle in such a way that the natural movement of the eyebrows is preserved.
Training as an oral and maxillofacial surgeon provides a solid foundation for understanding the anatomy of the facial muscles, nerves, and blood vessels, as well as for performing botulinum toxin treatments.
Who is a good candidate for forehead Botox?
Forehead Botox treatment is suitable for people who have horizontal forehead lines that are visible when they move or at rest. The treatment can help prevent the formation of forehead lines and also reduce existing lines.
Botox treatment for the forehead is common, especially among people who
- The wrinkles on the forehead are clearly visible when making facial expressions
- Permanent lines have formed on the forehead, which are visible even at rest
- The skin on my forehead feels constantly tight
