The effect of preventive Botox is temporary, and it generally lasts for 3-4 months; however, the exact time varies from one individual to another.
There are certain factors involved in it, such as an individual’s metabolism, treatment area, dose, and muscle activity, lifestyle, and maintenance.
As the effect of Botox wears off gradually, the muscles regain their normal activity. To maintain it for a long period of time, an individual needs to go for further follow-up treatments done by a dermatologist.

It is important to understand that preventive Botox is not a permanent solution; it only delays or slows the development of wrinkles. It does not permanently stop it.
There are several factors that should be maintained along with preventive Botox, and these are good skincare, sunscreen usage, and a healthy lifestyle for better
results.
