I have questions about the effects and pain of skin Botox.

I have oily skin and my pores are on the larger side, so I'm incredibly stressed about it.

On top of that, maybe because I'm getting older, I've developed wrinkles here and there lately.
I heard that skin Botox is very effective for skin texture.
Will it be effective for pores and wrinkles?
I heard it hurts a lot, so I'm curious how severe the pain will be.
