What would be the best first procedure for a middle-aged woman in her 40s?

I am a middle-aged woman in my 40s who has never had any cosmetic procedures. My cheeks around the corners of my mouth are sagging, and I have deep wrinkles on my forehead, making me look like a grumpy, stubborn middle-aged woman. I am also concerned about the pores on my nose.

So I want to get a procedure done, but since it's my first time, I'm not sure which one I should get first.

Please recommend the most satisfying and affordable one.
