[Skin Concerns] Is this skin damage possibly caused by BP 2.5% irreversible?

Beauty Tips For Body Care
Hello. After doing some poking around this subreddit I'm a bit freaked out about the treatment I've been using.I have struggled with acne since I was 9 years old. It got especially bad when I was 19. I've been to dermatologists with no success. The only thing that works for me is benzoyl peroxide 2.5%. Until I found this subreddit though I didn't understand the importance of moisturizer and SPF when using BP and slathered it on the sides of my face for a good 6+ years without taking proper measures. I now have dehydrated skin and major hyperpigmentation on top of textured scars, as you can see in this album. I also have some small, micro wrinkles on my cheeks around my nose (also shown). Are the wrinkles premature aging from the BP? If so, I know it's irreversible but if I stop using benzoyl peroxide will it slow the progression? What about the scarring? I realize there's not much to do about them, particularly the textured ones, but are they totally hopeless with no room for improvement?Another thing, is there a good first step to take after stopping the BP? Acne prevention is a major concern for me; as soon as I stop the BP the pimples start coming back within days. I'd like to introduce my new routine slowly, as recommended, but I'm not sure what the most important part for acne prevention is. An AHA?Tl;dr: Are the little wrinkles around my nose (shown in the first photo here) premature aging? If so, can I stop the progression by stopping the use of BP 2.5%? Is there any hope for my acne scarring?
