About two weeks ago, I woke up with three small patches about .15" wide on my hand, one is much more faded than the other two. They changed from a light pink to a darker brownish-pink over the two weeks, especially in the sun. They don't seem to be raised at all and the two bigger ones are only a very, very slightly rougher texture than the rest of my skin, almost imperceptibly.
They are not itchy and not dry. They don't bother me at all. But I'm concerned because they came so suddenly and are not fading at all, but seem to be getting more noticeable. What could it be? Is it anything to be concerned about?
Thanks for your help!
