My acne has been coming back recently. Could you please tell me how to manage it?

Hello ^^ I am a man in my 40s

I'm worried because acne has been coming back on my face recently.

Are there any age-appropriate acne management methods?

I'm especially curious about acne management routines and product recommendations that can be followed while working!

Also, if there is any acne management method that can reduce trouble after shaving, please let me know.

Even after shaving, I always get acne around my mouth and chin, which is stressful.

I wonder if there is something wrong with the razor blade... or maybe my skin is sensitive and the blade touches it.

I'm also wondering if I'm getting acne
