3 deliverables in this treatment
- Assessment of the masseter muscles and dose planning
- Botulinum toxin injection into both masseters
- Aftercare guidance
Botulinum toxin injected into the masseter (chewing) muscles to slim and narrow the lower face and soften a square jawline. At Estemedic MUDr. Ilona Karasová places the toxin through a fine needle so the bulky masseter muscles relax first and then gradually reduce in size, refining the contour of the lower face. Unlike upper-face wrinkle treatment the slimming effect is gradual, building over several weeks, and many people also notice reduced jaw tension if they clench or grind. The effect lasts several months before periodic repetition. The treatment starts from 8,000 Kč and is non-surgical with no downtime.
