What is the difference between regular Botox and skin Botox?

I have always been concerned about my rough skin texture and fine lines, so I was looking into dermatological procedures when I first came across the term "Skin Botox." I am not exactly sure how it differs from the standard Botox I know, so I am looking up personal experiences before my consultation. I read explanations stating that Skin Botox is designed to manage subtle skin concerns rather than restricting muscle movement, and I am curious if the actual procedure works in that way. I would also like to know if I can expect to see improvements in pore size or skin texture after receiving the treatment. I prioritize natural changes above all else, as I do not want my facial expressions to look unnatural. I am curious to know what aspects of Skin Botox those who have actually received it were most satisfied with. Please also let me know if I can return to my daily life immediately after the procedure, and how long any redness or uneven marks last. Since this is my first time, I do not want to raise my expectations too high, so I would like to hear about both the pros and cons based on actual experiences.
