Works well for my ruddy complexion. I don't know if I have rosacea but I am definitely prone to redness and dilated capillaries. I get this about every 4-6 months. With every treatment there are a few capillaries that it 'kills off' and I can see them shrivel up. Most however just shrink in response to the treatment. Gives a nice glow for a day or two. For me, requires follow up treatments 2-3 times per year.
