I take ortho tri cyclin, and I recently developed Melasma (brown spots under my eyes, on my upper lip and my forehead) and I cannot go in the sun and even with lots of makeup I cant cover it totally. My dr just referred me to a dermatologist and suggested I stay away from a Tri cyclic and do a low dose BCP in the meantime. SO she just changed me to Loestrin until I can see the dermatologist and get this worked out.
I would avoid the three color kind of pills just in case!! Having this is so awful, it looks like I have a mustache if i go in the sun. So all summer I have had to hide from the sunshine, and use creams to make it go away. I have been told by some of my coworkers that it takes months to go away and will not go away unless I stop taking bcp altogether, but I will let you know after I see the derm!!
So go with the low dose if you can.
