Please give me some acne management tips.

I'm a working man. I've suffered from chronic acne and red, inflamed scars since I was young, which has left me with a low self-confidence in my appearance and has even caused me to shy away from social interactions. Especially after shaving, my chin area is always covered in breakouts, which is incredibly stressful and irritating.

I have combination skin with excessive oiliness, and I'm not sure what cosmetics to use for acne management. I'd like recommendations for a gentle, sebum-regulating, and effective acne-calming skincare routine specifically for men, or a simple, yet effective skincare routine. If you have any acne-fighting essentials like ampoules or serums that have shown noticeable soothing effects in a short period of time, please share them with us!
