Botox treatment is most commonly performed on the forehead. The procedure can prevent, reduce, and correct forehead wrinkles. The treatment relaxes the forehead muscle (m. frontalis). As the muscle relaxes, the skin overlying it smooths out, and forehead wrinkles become less pronounced or disappear completely.
After a botulinum toxin treatment on the forehead, the first changes become visible within a few days. The results are visible and can be assessed 2–3 weeks after the treatment.
If the forehead lines are deep and the upper eyelids are heavy, the treatment is quite complex. In such cases, the best results are achieved by injecting Botox not only into the forehead but also between the eyebrows and, if necessary, into the outer corners of the eyes.

The Best Way to Get Rid of Forehead Wrinkles with Botox – Treatment of 3 Areas
When treating horizontal forehead lines, Botox is almost always injected between the eyebrows as well, and often into the outer corners of the eyes. Doing so helps smooth out forehead wrinkles without causing the eyebrows to droop.
This Is How Forehead Wrinkles Form
Forehead wrinkles are directly related to the activity of the facial muscles. The frontalis muscle shown in the anatomical diagram (below) is responsible for raising the eyebrows. At the same time, it creates horizontal wrinkles on the forehead.
In botulinum toxin treatment, the activity of the frontalis muscle is reduced through small injections. As the muscle relaxes, the skin also smooths out. However, facial expressions remain natural.
Horizontal forehead wrinkles are mainly caused by the contraction of the frontalis muscle. When this muscle is repeatedly activated—for example, when raising the eyebrows—the skin wrinkles horizontally. Botox treatment reduces muscle activity and smooths out forehead wrinkles.
Get rid of forehead wrinkles with Botox
Botox— or botulinum toxin—treatment is one of the most effective ways to reduce forehead wrinkles. The earlier forehead wrinkles are treated, the more effectively their deepening can be prevented.
The best results are seen 2–3 weeks after treatment.
Any additional injections into the forehead are administered 2–4 weeks after the initial procedure (a so-called free follow-up visit).
The results peak between weeks 2 and 6.
The effects of Botox begin to wear off gradually starting in the sixth week. The effects fade slowly, and a good result lasts an average of four months.
Treatment is usually repeated every 3 to 6 months.
Unless the treatment is repeated, the muscle will fully return to its original condition within 12 months. Of course, the visible effects will disappear much earlier than that.
Injection sites
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.

Botox is one of the most extensively studied aesthetic treatment methods. When performed correctly, the treatment is safe and well-tolerated.
“Before I started getting Botox, the lines on my forehead and my frown lines had already become really deep, and my forehead, facial expressions, and gestures have always been very pronounced, which of course makes the lines on my forehead much deeper.”
