[Question] How should I manage acne-prone skin as well as age-related moles?

I didn't have crater-sized acne like in the photo, but I had small pimples all over my face, and the marks are still there.

Of course, there are still some acne spots left.

However, as I get older, it seems like I am seeing new traits appearing one by one that I didn't have before.

As if things weren't bad enough, my freckles are gradually increasing, and honestly, I can't handle it anymore.

I wonder if it's too late to start managing it now, but I also think it might be right to start doing it little by little.

It is a place that has never been touched before, so it is difficult to even attempt to work on it.

I am wondering what approach would be the most cost-effective, least painful, and effective.

I would appreciate it if the experts could share their good experiences.
