My mom has rosacea, too. Ive always burned easily & had skin cancer 12 years ago, so I really avoid the sun. I think rosacea tends to run in people of fair complexion, too. I had very pale skin my whole life until my 30s when the flushing started.
Diana - you may need more than 1 treatment before you see results. My doctor told me that I would need at least 5 treatments and probably wouldn't start to see results until the 3rd. My treatments were spaced 1 month apart and I had 6 total the first year. Unfortunately I don't know what settings were used. She did use a smaller wand on the red spider lines and they disappeared on the spot.
She took a before and after photo of me and there is a very big difference. And, as I mentioned - I still go for 2 maintenance treatments each year.
Good luck!
Donna
