My face has lost elasticity and is sagging. What is the treatment schedule for Skin Botox?

Lately, when I wake up, pillow marks don't disappear for over half a day, and I feel like my skin is sagging all over. ㅠㅠ As my elasticity drops, my pores seem to be stretching vertically, and I feel so depressed every time I look in the mirror. Haha. No matter how good the cosmetics I use are, it feels like there are limits to home care, so I'm planning to get help from a dermatologist! They apply it densely all over the face. Skin Botox I heard that getting it done is really good for elasticity and tightening pores. Is that true? Usually Skin Botox I'm wondering how long the effects of the treatment last. To definitely keep my skin firm... Skin Botox Does anyone know roughly how often I need to go get the shots? Haha. I'm such a scaredy-cat and afraid of the pain, so if you have any tips, please leave lots of comments! ㅠㅠ
