Hi! I have not been diagnosed with lupus yet, but I do have a butterfly rash across my cheeks. Mine is always there to some degree. It gets worse when I have a flare or forget my sunscreen. Like you, mine looks ok with makeup but bad without it. I have had it for several years. I really didn't realized what it was until a few years ago when my doc mentioned lupus. Mine also gets worse after a hot bath.
Hope this helps
Donna
