1)Shouldn't the red have diminished SOMEWHAT in 9 days?
Not necessarily. It can take longer.
2)What length of time can I expect the redness to last?
If you leave it alone and don't rub, perhaps a month or two.
3)Is there anything I can do to reduce the redness? I have been using hydrocortisone 1% per my physician for a few days, but no results yet. Should I continue its use? Is there a better treatment?
No. The best treatment for redness is no treatment (or cover-up.)
4)What would be some indicators that it is infected and not just inflamed?
Infection would show itself as scabbing, oozing, etc. Doesn't sound like it.
5)Can ultraviolet rays hinder the healing process?
No.
6)Again, how long should the redness last and what is the best way to treat it?
These are repeat questions. Please see answers above.
