Botulinum toxin · Chin
Chin botulinum toxin
The chin muscle, the mentalis, contracts when you talk, when you close your mouth firmly and when you pout. In many people that contraction wrinkles the skin of the chin, the orange-peel texture, and pulls the chin upwards.

Botulinum toxin relaxes the mentalis. The skin smooths and the chin stops rising when you talk. The dose is small and the effect discreet: the chin smooths out and nobody asks why.
A 15-minute session, €120. It pairs well with chin filler when the chin also lacks projection.
What changes with chin botulinum toxin
A small dose of botulinum toxin in the mentalis, the chin muscle. It stops the skin turning grainy, the orange-peel texture, and stops the chin rising when you talk.
Is it for you?
A chin that wrinkles when you speak, close your mouth firmly or pout. Common in men and women; the dose follows the strength of each muscle.
What happens in the session
One or two injection points. No anaesthetic. Fifteen minutes, then back to your day.
What you'll see, and when
First signs at 3 days, complete by day 14. It lasts 3 to 4 months. The effect is discreet: a smoother chin, nothing anyone can point to.
After the treatment
Nothing to recover from. Avoid rubbing the chin for the first 4 hours. A red dot may stay for a few hours.
Why it looks natural
The mentalis plays almost no part in expression, which makes this one of the most forgiving areas: relaxing it changes nothing else in the face. The dose follows the strength of the muscle, and the effect is discreet by design: a chin that stays smooth when you speak.
Honest answers
Will it show? First signs at 3 days, complete by day 14. A red dot may stay for a few hours.
Does it hurt? One or two quick injections, no anaesthetic. Brief pinpricks, then back to your day.
What if I don't like it? The toxin cannot be dissolved; it wears off on its own in 3 to 4 months, and the first dose is kept conservative for exactly that reason.
How we do it at Cosmo Clinic
The mentalis plays almost no part in expression, so relaxing it changes nothing else in the face. When the chin is short, the muscle works harder to compensate; relaxing it and adding projection with chin filler solves both, in one session or two. €120. The assessment consultation is free.

Frequently asked questions
Short answers to the questions we hear every day. Everything else belongs in the consultation.
What is an orange-peel chin?
Chin skin that turns grainy when the mentalis contracts. It happens when you talk, close your mouth or even at rest, in people with a very active muscle or a short chin.
How long does it last?
Between 3 and 4 months.
Does it affect my expression?
No. The mentalis plays almost no part in expression; relaxing it removes the roughness and leaves the rest as it was.
Is it for men and women?
Yes. It is common in both, and the dose follows the strength of the muscle.
Does it hurt?
One or two quick injections. We do not use anaesthetic.
Do I need any downtime?
No. Avoid rubbing the chin for the first 4 hours. A red dot may stay for a few hours.
Can I combine it with chin filler?
Yes. When the chin is short, the muscle contracts harder to compensate. Relaxing the muscle and adding projection with hyaluronic acid solves both, in one session or two.
When do I see the result?
You see it start at 3 days; the day-14 result is the complete one.
