What treatments are available to improve pores?

When I had acne as a teenager, I used to squeeze it frequently with my hands, and perhaps because I didn't manage it properly back then, my pores have become very enlarged now. It makes me even more upset because no matter how much money I spend, I've heard that it is difficult to completely get rid of enlarged pores. Still, I would like to know if there is any way to soothe or improve them even a little. My wish is to be able to go out comfortably with a bare face without worrying about makeup, such as when going on a trip of one or more nights or taking a flight. If there is a treatment that you have actually seen results from for pores and that provides some lasting effects, please recommend it.

Also, is it impossible to get rid of those dark spots inside the pores? I think they make my pores look even more prominent.
