I feel your pain Shiroi, suffering from the same conditions myself. What worked better than any prescription I ever received for acne & especially Rosacea was LUSH brand cosmetics applied with a Clarisonic Spin Brush.
LUSH is all natural, handmade fresh in small batches, and cruelty free. I like the Fresh Farmacy Bar & the Celestial moisturizer, though be careful about storing the bar-I left mine in the shower & the exterior dried out after about 2 months (I just scraped it off, but still). I've heard great things about their Aqua Marina seaweed cleanser, so I was thinking of trying it soon. They serve several countries world wide, just click on your nationality when you enter their site.
The Clarisinic Spin Brush brings all the bacteria, oils & dead skin deep within pores to the surface, so the acne MAY get worse initially, but will clear after a week or so. That's what most call the "purge phase". I ordered mine in mid April from Sephora (I like to build up my beauty bank points with them for free items), but they're sold all over, so I'm sure you can find a reputable site that sells them.
I swear by both & have noticed a marked improvement since I started using them.
