I've got rosecea as well....a friend who had it told me that's what it was, so I went to a dermatologist, and sure enough. That was a relief in a way... I'd had pimples as a teen, that stopped during a year I lived in a very sunny place, and then then started coming back years later. It is definitely aggravated by spicy foods, heat, alcohol... I guess anything that brings the blood to your face. You look soused after half a glass of wine, and if you have it badly and don't do something about it you wind up with a WC Fields nose even if you don't really drink much. Back when I was first diagnosed they said it was caused by a permanent skin infection which could be kept under control with topical creams...prescription creams...to which eventually the bacteria or whatever would develop resistance, then you move on to another one, and eventually to streptomycin taken internally. I have to say the creams worked wonders (on my second one now), although I still flush easily in heat and with alcohol. No more pimples though! I imagine changing your internal flora and sugar levels could make things less hospitable for whatever causes it... so not surprising that some of the things suggested here work.
mrd, I use the most basic Oil of Olay product on my face and hands twice a day and have for years, and definitely look younger than my age skin wise. I also avoid "soap"....use Dove or Camay once a day, just wipe off make up and dirt at night and cream up. In the last few years I use Oil of Olay eye cream...in a minature sort of squirt bottle thingy... definitely more expensive than the basic stuff. I also use an aloe cream....giant bottle of something from Vaseline I think. Anything with aloe and/or lanolin works wonders. Really heals up your skin.
Overall I wash with a goat's milk soap--I know, sounds like Cleopatra... but your skin feels so smooth afterwards; an acquaintance who had a job washing elderly people at a nursing home (all day in the showers with them basically) whose skin was a mess on her arms started using it and it completely healed her up. I order it...a little expensive if you just order one bar because of shipping, but if you like it you can get a number of bars at once. I just get the plain version, but it also comes with lavender, etc. "Free range" hand milked goats, too! And cute goat pictures on the website! sally b. farms is the website.
sweet_lady---there are lot of warnings about Retin-A and pregnancy...causes skull mutations in fetal rats. So not recommended if you are or could become pregnant. According to Wikipedia it also is a good idea to avoid waxing for hair removal as the skin is so thin after using it....
