- Anti-Wrinkle Treatment (Botox)
✨ Slim your jawline and stop teeth grinding in one treatment — no surgery, no downtime.
How it works:
- Azzalure botulinum toxin is injected into the masseter muscles at the jaw angle. This blocks the nerve signals that make the muscle contract, so it relaxes and gradually shrinks over the following weeks. Smaller muscles mean a slimmer, more V-shaped lower face. For teeth grinders, the same relaxation stops the clenching force that wears down teeth and causes morning headaches.
Who it's for:
- Anyone with a wide, square lower face caused by bulky chewing muscles rather than bone or fat
- People who grind or clench their teeth, especially at night, and want to protect their teeth and relieve jaw tension
- Those who have tried night guards but still wake with jaw ache or headaches
The benefits:
- Jawline looks noticeably slimmer and more contoured within a month
- Teeth grinding stops or reduces dramatically — protecting enamel and reducing morning pain
- Tension headaches and jaw ache fade as the muscle relaxes
- No surgery, no scarring, no general anaesthetic
- Result looks natural — you still chew normally, just with less bulk and force
What's included:
- Full consultation with Bella to confirm your masseter muscles are the right target
- Precise injection into 3–4 points per side using a fine needle
- Ice or cooling if needed for comfort
- Written aftercare instructions
- Free review at 2 weeks if needed
What to expect:
- One session only — no course needed
- Grinding relief starts within a week; jaw slimming shows at 4–6 weeks
- Lasts 4–6 months, then you can choose to repeat
- Book at least 6 weeks before any event so the slimming is fully visible
💡 You'll still chew and smile normally — the muscle is simply less bulky and less forceful, not paralysed.
Common questions
Is there any downtime?
You'll have small bumps at the injection points for about an hour, and some people get a little bruise or tenderness for a day or two. Most people go straight back to work or their normal day.
Does it hurt?
It's quite manageable — the needle is fine and the injection goes into the muscle rather than near bone, so most people describe it as a brief dull ache rather than anything sharp. Ice helps if you want it.
How many sessions will I need?
Most people need just one session, then they repeat every four to six months when the effect starts to wear off. If you have a wedding or big event coming up, book at least six weeks beforehand so the slimming has time to show.
How long do the results last?
You'll usually notice grinding relief within a few days, and the jaw slimming shows properly at about four to six weeks. From there it typically lasts four to six months before the muscle gradually builds back up.
Are there any side effects?
It's normal to have some tenderness, a headache, or a small bruise afterwards, and your jaw may feel tired when you chew for the first week or two. Rarely the smile can look slightly uneven if the toxin spreads, but this settles. Very rarely there can be eyelid drooping, difficulty swallowing, or speech changes — these need urgent medical attention.
