Botulinum toxin · Forehead
Forehead botulinum toxin
The horizontal lines across the forehead come from the frontalis, the muscle that raises your brows a few thousand times a day. Botulinum toxin relaxes it just enough for the skin to stop creasing. The forehead still moves; it stops leaving a mark.

The dose is everything. Too little and the lines are back in weeks. Too much and the forehead freezes, the brows drop and the eyes look heavy. At the consultation we watch how you use your forehead when you talk and smile, where your brows sit at rest, and whether the frown lines need treating at the same time. The dose comes from that, not from a chart.
The session takes 15 minutes and costs €189. You leave and carry on with your day.
What changes with forehead treatment
Botulinum toxin in the frontalis, the muscle that raises your brows a few thousand times a day. Relaxed just enough, the skin stops creasing. The forehead still moves; it stops leaving a mark.
Is it for you?
Anyone who sees the horizontal lines at rest, or sees them starting. Age matters less than the muscle: some foreheads mark at 28, others not until 45. If it does not make sense for you, we say so.
What happens in the session
We watch how you use your forehead and where your brows sit at rest. That is what sets the dose. Shallow injections, no anaesthetic. Fifteen minutes.
What you'll see, and when
First signs at 3 days, complete by day 14. It lasts 3 to 6 months, and the interval tends to grow with regular treatment.
After the treatment
For the first 4 hours, avoid lying down, rubbing the area or hard exercise. A red dot or a mild headache can happen and passes.
Why it looks natural
A frozen forehead is almost always too much dose. Too much toxin and the brows drop and the eyes look heavy. So the dose comes from watching your face: how you use the forehead when you talk, where the brows sit at rest, whether the frown lines need treating at the same time. The forehead keeps moving; it stops leaving a mark.
Honest answers
Will it show? Not on day one. First signs at 3 days, the full result at 14. A red dot at an injection point can last a few hours.
Does it hurt? The injections are shallow and very small, with no anaesthetic. Most people describe a light pinprick that passes in seconds.
What if I don't like it? Botulinum toxin cannot be dissolved; it wears off on its own in 3 to 6 months. That is one reason we keep the first dose conservative.
How we do it at Cosmo Clinic
Brow position is checked before a single injection. Low or heavy brows call for a smaller dose and often for treating the frown lines at the same time, which helps lift them. Both areas together cost €249; the forehead alone €189. The consultation is free.

Frequently asked questions
Short answers to the questions we hear every day. Everything else belongs in the consultation.
Who is forehead botulinum toxin for?
Anyone who already sees the horizontal lines at rest, or sees them starting. Age matters less than the muscle: some foreheads mark at 28, others not until 45. At the consultation we tell you whether it makes sense for you, and if it does not, we say so.
How long does it last?
Between 3 and 6 months. It depends on your metabolism, the strength of the muscle and the dose. People who repeat it regularly tend to see the interval grow.
Will I still be able to move my forehead?
Yes. The aim is to reduce the contraction that creases the skin; the muscle keeps working. If you would rather have an almost still forehead, say so at the consultation; the dose is yours to choose.
What are the risks?
It is one of the most studied procedures in aesthetic medicine. The most common side effects are a small bruise at an injection point, a mild headache in the first hours and, rarely, a brow that drops for a few weeks. Checking brow position before injecting is what prevents the last one.
Does it hurt?
The injections are shallow and very small. Most people describe a light pinprick that passes in seconds. We do not use anaesthetic in this area.
Do I need any downtime?
No. You may have a red dot or a small bump for a few hours. For the first 4 hours, avoid lying down, rubbing the area or hard exercise.
How do you stop the brows from dropping?
We look at where your brows sit before injecting. Low or heavy brows call for a smaller dose on the forehead and, often, treating the frown lines at the same time, which helps lift them.
What if the line is already there at rest?
The toxin reduces the movement, but a line that has already settled in may not disappear completely. In those cases a small amount of hyaluronic acid softens what remains. We look at it case by case.
