Rosacea is a condition that can happen to every skin color, man or woman. I inherited it from my mother, and I remember a black female classmate wound up getting rosacea back then (since black or brown skin cannot flush red, rosacea looks more like a combination of a rash with a cluster of pimples from what I remember).
This is a product that I discovered helped with acne and rosacea:
I have used this I think three times. It does have a sulfur smell so I would recommend applying this before bed. I put a small amount on all of the areas rosachea can appear: nose, cheeks, chin. You can also dab some on a pimple anywhere else, including neck chest, and back.
