Rosacia

I just found out I have rosacia. I discovered red ness on both my cheeks which I ahd earlier thought to be dry skin. After about two years- i showed the Doctor and he said it looked like rosacia. So far I am using a topical application gel, with results. Please can someone explain how this came about in the first place. And, what causes it.

my face on one side has been red and had little pimples for about 3-4 months. at first it did't bother me because it was very unnoticeable, then lately it seems to be more pronounced and people are starting to ask what's wrong with my face.

I hear you, I also drink caffiene and smoke and have flare ups near my cycle the med's make my face clear up a little but I hate the light sensitivity I get with it.

Acne rosacea; acne erythematosa; vascular and follicular dilation involving the nose and contiguous portions of cheeks: may vary from very mild but persistent erytherma to extensive hyperplasia of the sebaceous glands with deep-seated papules and pustules of the affected erythematous sites.

Concerned about my unhealthy skin condition,(angry red skin, spots etc.)I decided to try the doctors, perhaps an allergy to a food has occured? My father has an intolerance to gluten, perhaps this could be the answer...The doctor suggested to trest me for Rosacia, however the cream that has been prescribed means that you have to keep out of sunlight! I mentioned this to a friend and she knows someone who used this cream and it resulted in her having to avoid sunlight for life! I have decided not to use this cream until I check out what else is available for the treatment of Rosacia.
Tea Tree oil is a natural antiseptic, so I shall try this first and also go to a Herbalist to see what they suggest..
Any comments or opinions, please do......
