I have my own questions about the effects of botox.

Recently, more and more people are considering botox injections to improve fine wrinkles and square jaws.
The frequency of the procedure also seems to be increasing.
It is clear that the botox effect after the procedure is satisfactory, but
Since the effects of Botox are generally described as lasting about 4 months, one wonders why one must continue receiving the treatment 2-3 times a year.

Even though the short-term effects of Botox are certain, I wonder if repeating these treatments every year like this will cause other problems to our bodies in the long term.
'I would like to know if there is any problem with the tolerance of this product, Botox.

Many people have already expressed their concerns, and as this is a product used by hundreds of thousands of people, it is believed that this process has been sufficiently verified.

I may be worried about something I don't have to do, but I'm curious so I'm posting this.

Regarding the effects of botox... Is there a good way to manage it by reducing the number of treatments while maintaining the effects for a long time, such as by doing treatments in parallel and spacing them out more frequently?
