I'm 25, and as far back as I can remember, I've had two-toned skin on both of my legs. I'm not talking about splotches or tan lines. I mean that on the insides of my legs, running from my knees down to ankles, I have a rather obvious line that separates light and dark skin. The skin gradually turns from light olive to tanned olive skin as it wraps around my leg--with the two ends meeting up like a seam running down the insides of my legs. The smooth color change thankfully isn't noticeable unless you see the seam. I've got seven siblings; I've asked them all, and none of them have this issue. Does anyone else have this going on? I mean, it seems like a rather strange birthmark.... (I would post a pic of it, but I can't seem to get it to photograph well.) Has anyone else heard of this? I'd love any ideas or opinions on what it might be. Thanks!
I never could understand this problem, but I have had it all my life as well. It runs down the side of both arms and down the back of both legs. The strangest thing is that the starting point is on my sternum and the lines shoot out in semi-circles to my shoulders. Then down the arms. I guess there is a medical explanation, but it sure looks weird. I used to joke that we are people who were kidnapped by aliens and had our skin ripped opened for some funky examination. Still looking for answers.
I have this same exact skin condition! I am a white female, Blonde hair, Green eyes, age 26 and have had these 2 toned skin colors separated by a distinct line my whole life. I have this on both my arms and both my legs and the tanner I get the more obvious it is. The lines that separates the two skin colors on my legs starts at my perineum and goes down the insides of my legs to my ankles. The lines on my arms start at my collar bone and travel down the inside of my arm to my wrists. The lines are identical to each other on my arms and my legs. Personally I think it looks kind of cool and it makes me unique from everyone else. I like to say I have 2 sides to me or I am a mutant. LOL! If anyone knows of a medical term for this condition let me know.
I'm African American..but the stripe down the backs of both legs is ligh/dark...from mid-thigh down it's like someone took a ruler and and colored my legs with two diff brown crayons. I'm 40 and had it since I was a child. ..when I wear shorts or skirts in the summer guaranteed I get asked, "why are your legs two different colors? I like it actually. .I always say its my birthmark...? Be great to know the reason. ..obviously its some kind of pigment issue?..
I'm asian, filipino, and I have brown skin and white skin. When I tried to get a tan under the sun, all I get is ruler around my arms of a very dark brown and the white just get a little bit of tan. Not only that, my whole body will have a different shades of dark brown and white. I have been trying to figure out until I watched one of these new science tv shows about a dark and lighter mice: their genetics are identical except for that light and dark genes that control their color. So I am concluding that my dual skin color is control by my gene inherited from my parents. For me this explains why I have 2 skin color of brown and white.
I have the same problem my whole life and i don't know how to get rid of the line. at first i thought as a kid i just didn't have a good hygiene but i when i get older as a teen i have a really good habit of scrubbing my thighs and legs at the back side. yet there's still no changes.
