Hi, i have rosacea and been reading on the internet that Tetracycline is a regular treatment and since i am going to a ner derm the 4th july she will problably prescribe me this. But now for me question i read that this dosent help the superficial blood vessels which i have on my booth cheeks something that could help this was lasertreatment but since i am from Peru and am brown skinned with dark hair im afriad i could harm my skin more then help it, or is there any lasertreatment for darker skin? thx
