Rosacea can look like acne, not just redness. In fact, years back, I was told it was acne, despite my very dry shin, and accordingly with a long course of ABs, which didn't make any impression on it, but caused havoc with my digestive system. With time, it settled down.
I have had outbreaks since and have been prescribed both AB and steroid creams, which didn't help either. Time again seems to help, along with looking at what aggravates it as it can be very sore and rather unsightly, I think, though I am told others don't notice it. Not even when I think I have Rudolf's nose!
I find protecting the area from the sun helps. A hat and sun cream that doesn't upset my rather sensitive skin. I've started using Clinique Redness solutions moisturiser and also the sunscreen in the range even in winter. Expensive, but maybe coincidence, but my skin has been more settled since I started using it. I do use a stronger sunscreen in strong sunshine. I wash with Epaderm cream/ointment as this suits my skin (dry with a tendency to eczema). I don't wear make up so often now, as removing it seemed to make my skin flare up. I'm more careful how I dry my face now, patting gently.
Really, it's a matter of finding out what suits you, taking more care and patience when you do have flare ups.
