Can acne red marks be managed?

I'm a 30-something office worker. I've been struggling with chronic acne for quite some time, and I think I've gotten better. But now, the red acne marks that remain have left my skin looking blotchy and uneven. These red acne marks always make my skin look dirty, and my confidence in my appearance has plummeted, which is stressful.

I have oily skin and a lot of sebum, but if I use expensive functional products to manage acne scars, it actually causes more breakouts. I'd like recommendations for serums or ampoules that quickly soothe and fade acne scars without irritation. I'd also appreciate it if you could share with me your actual acne scar removal routines, hospital treatments, and home care tips for men in their 30s.
