I constantly get red spots on my nose, which are very tender. No sooner do they calm down than they return in the same area. My doctor prescribed Rozex gel but it hardly makes any difference. I’m 75 and otherwise healthy.

This is most likely to be a form of rosacea, a disorder that commonly affects those aged 30 or over.
It is the result of changes in the immune response in the skin, which reacts to microorganisms that can live there, such as Bacillus olenorium and a microscopic mite called Demodex folliculorum. This triggers inflammation and spots.
