What can I do to make rosacea less noticeable?

DEAR DOCTOR K: I have rosacea, and it makes me very self-conscious. What can I do to make it less noticeable?
DEAR READER: Rosacea is a common, long-lasting skin condition that causes inflammation and redness of the face. As with many diseases, we don't know what causes rosacea. People with the condition are more likely to have high levels of certain natural inflammatory chemicals in their skin. There also is evidence that tiny little insects (dust mites) and a particular type of bacteria living on the skin can trigger rosacea. Rosacea usually progresses through four stages. In the first stage, a person has flushing and occasional facial redness.
