What are the actual effects of Skin Botox? I'm worried about my pores and fine lines.

My skin feels drier than before, and my pores are much more noticeable, so I’ve been looking into dermatological treatments lately. It’s particularly stressful because when I apply makeup, it feels like it settles into my fine lines rather than creating a smooth finish. Then I learned about "Skin Botox." Since the name is similar to regular Botox, I initially thought it was the same procedure. After looking it up, I learned it involves a shallow injection into the skin, but I’m curious to know exactly what the effects of Skin Botox are. What I’m hoping for isn't to stop my facial muscles from moving, but rather to have a smoother skin texture and make my pores and fine lines appear less prominent. I’d like to know if Skin Botox actually helps with these aspects and when the effects typically become noticeable. I’m also curious if the effects tend to last a long time or if I need to get it again after a certain period. Since this is my first time getting this treatment, I want to avoid getting an excessive amount. I would also like to hear from those who have received it about the specific effects they experienced, as well as any differences in skin texture or how it looked when applying makeup.
