I suffered from this in my 40s and then again in my 50s. I too never suffered from acne in my teens, very dry skin. I was prescribed antibiotics, which had no effect but did havoc with my digestive system. It faded on its own eventually. The 2nd time, I was told it was called Rosacea. I ignored it as best I could and again it eventually settled down. I’ve always used gentle face cleansers because of my dry skin and used Clinique Redness solutions to counteract the redness and my embarrassment. Make up helped reduce the redness, but I had to be very careful with cleansing. The good news is that I no longer have the problem in my 60s, though I can see slight redness where it was. Sad to see my daughter having similar problems and she had teenage acne.
