I'm worried about blackheads.

Blackheads have been a huge stress factor for me lately. Every time I see the blackheads around my nose and chin, my confidence plummets, and no matter how much I wash my face, they don't seem to improve. I've tried various products, but they haven't really helped, and I'm worried because they seem to only irritate my skin more. I cleanse thoroughly, but I don't know why they keep appearing. I'm not sure if I should go to a dermatologist or just try some consistent home care. If anyone could recommend any effective skincare methods or products, that would be incredibly helpful.
