Fillers · Jawline
Jawline filler
A defined jawline separates the face from the neck. With age, or by structure, that line blurs: the angle loses its edge and the skin above it slides. Hyaluronic acid redraws the angle and the line, and the face gets the boundary it was missing.

The jaw is an area of structure. We look at the profile, the chin, the angle in relation to the ear, and whether the skin is sagging or the bone is simply small. Men and women ask for different things: a sharper angle for one, a more continuous line for the other. A full jawline almost always needs more than one millilitre; the amount is decided at the consultation.
The session takes 30 minutes. It costs €299 per millilitre. It lasts 12 to 18 months.
What changes with jawline filler
Dense hyaluronic acid placed close to the bone, along the line and at the angle of the jaw. It redraws the boundary between face and neck. This is structural work.
Is it for you?
A jawline that has blurred with age, or one that structure never defined. Men and women ask for different things: a sharper angle for one, a more continuous line for the other. When the width comes from muscle instead of bone, the answer is the masseter. Sometimes both.
What happens in the session
Numbing cream, then the gel with a cannula, which means fewer bruises in an area with vessels. Thirty minutes.
What you'll see, and when
The same day; definitive at two weeks. Light swelling for 2 or 3 days. It lasts 12 to 18 months.
After the treatment
No gym, sauna or alcohol for 48 hours. A small bruise can happen in some cases.
Why it looks natural
A jawline is structure rather than volume, and the gel is chosen to match: dense, placed close to the bone with a cannula. The design differs by face: a sharper angle for one, a more continuous line for another, and when the width comes from muscle rather than bone, the answer is the masseter. The number of millilitres is agreed before we start, never improvised mid-session.
Honest answers
Will it show? The same day, with light swelling for 2 or 3 days; definitive at two weeks.
Does it hurt? Numbing cream first, then a cannula, which also means fewer bruises in an area with vessels.
What if I don't like it? Hyaluronic acid dissolves with hyaluronidase (€120), fully or partly.
How we do it at Cosmo Clinic
A full jawline, angle and line on both sides, usually needs 2 millilitres or more; we tell you the number before we start. It often makes sense with the chin at the front of the profile, or after masseter botulinum toxin has slimmed the muscle. €299 per millilitre. The consultation is free.

Frequently asked questions
Short answers to the questions we hear every day. Everything else belongs in the consultation.
How much product is needed?
A whole jawline, angle and line on both sides, usually needs 2 millilitres or more. We can treat the angle alone with less. We tell you the number before we start.
Will it make my face look masculine?
Only if that is the request. On a feminine face the line is continuous and the angle soft; on a masculine face the angle is sharper. It is a matter of where the product goes, and you decide it with us.
How long does it last?
Between 12 and 18 months. The area moves little and the dense gel stays put.
Can I combine it with the chin?
Yes, and often that is what makes sense: the chin gives projection at the front, the jawline gives the side boundary. They can be done in the same session.
Is it the same as treating the masseter?
No. Botulinum toxin in the masseter slims the lower face by relaxing the muscle. Filler adds definition to the bone. A wide face needs the first; a face with no angle needs the second. Sometimes both.
Does it hurt?
Numbing cream and lidocaine in the gel. With a cannula you feel pressure and some stretching, which passes in minutes.
What about recovery?
None. Light swelling for 2 or 3 days, a small bruise in some cases. No gym, sauna or alcohol for 48 hours.
