Yep, I have been diagnosed with this. But unlike normal acne, it is not greasy, but sore. My GP said it was likely to be hormone related, not diet.
I first had a bout in my 40s, but it receded, but sadly has come back with a vengeance in my 60s. I'm afraid it hasn't responded to either AB cream or cortisone cream.
There are quite a few ladies who this problem here.
At the moment my nose is as red as Rudolf the reindeer's. Sadly, putting on foundation cream, including a recommended make, which would lessen the appearance of the redness, aggravates it. I wouldn't mind if I could cover it with makeup. I'm told it isn't that bad and people see me, not any blemishes. I know what they mean, as it doesn't worry me when others have blemishes etc, but it's different when it's your own face.
