You know, black, you'd think that by the time we hit our 40's we'd be able to leave acne behind as we get ready to embrace menopause, but I have the same problem.
For me, though, it's any type of foundation. I wear makeup only rarely because of it and when I do, I'm sure to be trying to clear up an unwelcome harvest of zits for the next week or two. Since I'm not willing to spend 50 bucks for a bottle of foundation that may or may not have the same effect, I just skip it unless I simply can't avoid it.
I keep hoping I'll outgrow it eventually...I'd hate to think I'll still be getting zits when I'm in my 80's and asking my grandchildren if I can borrow their acne cream!
