Botox: How It Works, Who It Suits and Recovery
What is Botox?
Botulinum toxin temporarily blocks acetylcholine release at the nerve ending, which reduces contraction of the injected muscle. It is used to soften expression lines and to slim enlarged jaw (masseter) or trapezius muscles.
Common concerns
- Forehead, frown and crow's-feet lines
- Square jaw (masseter hypertrophy)
- Trapezius (shoulder) line
- Chin dimpling
Treatment areas: forehead, glabella, eyes, masseter, chin, trapezius, calves.

- Device / product: Botulinum toxin
- Treatment time: about 10–20 minutes
- Anaesthesia: numbing cream or cooling if needed
- Downtime: minimal (small needle marks or bruises are possible)

Frequently Asked Questions
Can you become resistant to Botox?
Antibody formation has been reported with very frequent, high-dose treatment. Using the needed dose at appropriate intervals is the usual recommendation.
How long until a slimmer jawline shows?
Masseter volume decreases gradually; many people notice a change after 4–6 weeks, with individual variation.
Can I wear makeup right after Botox?
Light makeup is generally fine once needle marks settle, but avoid pressing or rubbing the treated area on the day.
