The injected Botox works beneath the skin’s surface and targets the underlying muscle activity that causes formation of wrinkles overtime. Normally when we squint, frown or make other facial expressions, our nerves release a neurotransmitter chemical – acetylcholine. This neurotransmitter binds to receptors within the muscle to make it contract.
Botox binds to the acetylcholine receptors and blocks the signals from the nerve to the muscle, resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles responsible for the formation of wrinkles.
The binding process starts within 48 hours of the treatment its impact on the skin starts showing within 10 days.
