You can’t cure rosacea (bummer) but you can control it and minimize breakouts and flares. The problem is that everyone who has rosacea may have different things that trigger it and it may not respond to the exact same treatment for every person who has it (another bummer.)
In my personal experience, the only way I got my disfiguring rosacea under control was with a specialist dermatologist after years of trying every home acne treatment I could find. Once my doctor got my skin cleared up with medication, we moved on to ways I can reduce my rosacea flares without meds.

Before we go any further, let me remind you that I’m not a doctor. I strongly suggest that you see a dermatologist if you have acne that never goes away or you suspect your constant red face is rosacea.
The National Rosacea Society has some good information and resources if you need them. This isn't an ad. I find them helpful if I have a question in between doctor's appointments.
