Hey,
I realize this is a very late response but I am bored at work and browsing.
This is very funny because I just noticed these white spots in my arm. i am actually tan for thew first time after returning from a semester in South Africa. I have never been tan enough to notice but now, BIG contrast.
I got really excited when I found them because I have either OA or OCA2 and but for being pale I have "normal" coloring, brown hair, freckles, moles, etc. People don't believe I have albinism (it takes a lot of educating my friends) so getting to show my friends that I do actually have albinism (even if it is totally unrelated) is fun. They now refer to them as "albino spots."
In reality, I have no idea what they actually are haha
