🤔 Will forehead Botox wrinkles get deeper once the effects wear off?

I recently received forehead Botox for the first time. I tend to use my forehead muscles a lot when opening my eyes wide or moving my eyebrows, so I was concerned about the horizontal wrinkles on my forehead getting deeper. In particular, as I entered my 40s, I was bothered by the faint wrinkles that remained even when I wasn't making facial expressions, so I decided to get the procedure done.

It has been about a week since the procedure, and I am more satisfied than I expected. Before, when I opened my eyes wide, distinct horizontal lines would appear on my forehead, but now, even when I open my eyes wide, the wrinkles don't form deeply. Fortunately, I don't feel any heaviness in my eyes or drooping of my eyebrows. So, I am satisfied with the current results, but since the effects are actually so good... I became curious about what happens when this effect disappears later.

I am curious whether the wrinkles return to their previous state as the forehead muscles move again once the effects of Botox wear off, or if the wrinkles become less deep than before if I get injections repeatedly over a certain period.

For those who have received forehead Botox multiple times, how did your forehead wrinkles actually change after the effects wore off?

I would also like to hear your experiences regarding whether there was a difference in wrinkles or the duration of the results between the first time and when you received repeated treatments.
