Why do I have deep redness running down my nasolabial folds?

I started with a thin "red-line" down one of my nasolabial folds last year or so. About 8-10 months ago I had matching one on other side. Now it seems almost over night, but actually in a couple of months, the redness on each side has expanded a GREAT DEAL! Makeup doesn't even cover sufficiently. Also, I have been dealing with a spot of the same kind of redness under each nostril for a couple of years. It is annoying but I could cover it. Now the same kind of redness is running down EACH nasolabial fold. It does not have any kind of pustules. It just is redness. It gets worse each day and I am extremely distressed. I have always been complimented on my clear skin. Just again yesterday that people can't believe my age since I am pretty wrinkle free, lol, thanks to always staying out of the sun my whole life. But this redness is making me not want to leave my house. I guess I am spoiled with my previously blemish free skin. Lastly, trying to find my own remedy, I have been putting lemon juice on the spots for a week or so. I read they are natural bleachers.I am in late 50's.
