I would like to inquire about Skin Botox for skin elasticity and pore improvement.

Hello. As I get older, I am very concerned because my facial elasticity is decreasing overall and my pores seem to be getting wider. My skin looks dull every time I look in the mirror, so while researching, I learned about a procedure called "Skin Botox," which involves injecting a fine layer of Botox into the outer surface of the skin. I am wondering if this procedure is truly effective for overall skin lifting and tightening fine lines. I have heard that it is slightly more painful than regular procedures, so I am worried if it will be bearable if anesthetic cream is applied. Generally, how often should I get Skin Botox to maintain its effects? I would also like to receive a rough estimate of the cost along with your recommended treatment frequency. Thank you.
