Most facial dynamic wrinkles are caused by the over-activation of muscles generated by excessive facial expressions. BOTOX® can reduce these wrinkles by blocking the transmission between nerve endings and facial muscles, making the over activated muscles flaccid so as to smooth out the established wrinkles .
In normal cases, the brain would transmit signals of chemical electrodes through acetylcholine to muscles, making them contract and move.
If excessive acetylcholine is released, the muscles would become tense due to the over activation, leading to the formation of wrinkles. Since BOTOX® can block the nerve endings from emitting acetylcholine, it can make the facial muscles flaccid so as to smooth the wrinkles.
How Often Should I Get BOTOX® Injection?
BOTOX® is supposed to be injected once every 6 to 9 months as this toxin-free natural protein is easy for the human body to absorb and decompose and thus no permanent results can be achieved.
How Long Does It Take for BOTOX® to Work?
In general, it will take effect 2 to 3 days after the injection. The full effects can be seen on the 7th day and generally last for 6 to 9 months.
Is BOTOX® Safe?
Though extracted from Botulinum toxin type A, BOTOX® is a natural protein instead of any type of toxins or bacteria and thus no bacterial poisoning or infections will be caused. The injection is administered by doctors to ensure safety.
