Over time, the muscles above and between the eyebrows repeatedly contract and tighten, causing wrinkles. Botox® / Dysport® works beneath the skin’s surface and targets the underlying muscle activity that causes frown lines and crow’s feet to form over time.
When we squint, frown, or make facial expressions, your nerves release a neurotransmitter chemical known as acetylcholine. This neurotransmitter binds to receptors within the muscle to make it contract. Botox® / Dysport®work by binding to the acetylcholine receptors, and blocking the signal from the nerve to the muscles. After a muscle has been injected, the nerves still send the signal to the muscle to contract, and the acetylcholine is still released, but is unable to bind to the muscle, resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines.
The binding process typically begins within about 48 hours from the time it is injected into the muscle, and results typically become noticeable within 7 to 10 days. While results are often most noticeable in dynamic wrinkles (wrinkles that appear when a muscle contracts), it can also help soften wrinkles that are present even without muscle contraction.
If wrinkles and frown lines are a concern, this is one of the best treatments available with yielding quick and noticeable results
