A strong, defined jawline is consistently rated as one of the most attractive male facial features. And thanks to modern aesthetics, you don't need surgery or genetics to get one. Jawline treatments for men have grown faster than almost any other aesthetic procedure — here's everything you need to know.
Two Treatments, Two Goals
There are two distinct jawline treatments for men, and they do completely different things. Masseter Botox slims and relaxes the jaw. Jawline filler adds structure and definition. Many men get both.
Masseter Botox (Jaw Slimming)

In men who grind their teeth, clench under stress, or simply have naturally large masseters, this muscle can make the lower face look wide, square, and heavy. Botox injected into the masseter relaxes and gradually shrinks it, creating a slimmer, more V-shaped jawline.
Masseter Botox details:
- •Units: 25-50 per side (50-100 total)
- •Cost: $400-$1,200
- •Results visible: 4-6 weeks (muscle takes time to slim)
- •Duration: 4-6 months
- •Bonus: Also treats teeth grinding (bruxism) and jaw tension/TMJ pain
Jawline Filler (Definition & Structure)
Jawline filler uses hyaluronic acid gel injected along the jawline and chin to add definition, straighten the jaw angle, and create a stronger profile. For men with a weak chin or undefined jaw, this can be one of the most transformative non-surgical treatments available.

- •Product: 2-4 syringes of Juvederm Volux, Restylane Defyne, or similar
- •Cost: $1,500-$4,000
- •Results visible: Immediately
- •Duration: 12-18 months
- •The effect: A more angular, defined jawline that looks natural and masculine
The combination play: Masseter Botox + jawline filler together creates the most dramatic results. Botox slims the wide part while filler defines the angle. Many providers recommend this as a package.
Who's a Good Candidate
You might be a good candidate if:
- •You feel your jawline is undefined or weak in profile
- •You grind your teeth or clench your jaw under stress
- •Your lower face looks wide or 'puffy'
- •You want a more angular, chiseled look without surgery
- •You've lost jawline definition with age

Jawline filler appointments take 30-45 minutes. You'll see results immediately, though there may be minor swelling for 1-3 days. Masseter Botox takes just 10-15 minutes but results develop gradually over 4-6 weeks as the muscle relaxes and slims. Neither has significant downtime — most men return to normal activities the same day.
