Acne that cannot be solved with patches

I don't usually drink alcohol, I cleanse properly, and I use the same skincare routine and face masks.

Sometimes, I get one or two hard, red breakouts.

Usually, if you put on a patch, acne either subsides or festers, but this kind of trouble

Applying a patch is no use. It goes away over time, but sometimes that part turns black.

I sometimes experience hyperpigmentation. How do you care for this kind of trouble?
