I have no idea why my skintone on my upper thigh is like that. I hate! I feel like crying every time I look at it. Do 你 know what this is. Also this is nothing to joke about! I'll 报道 anyone that says something rude
The lighting looks yellow, so it's kind of hard to tell. But I'm not one to know about skin tones but I don't think that should mean something terrible is wrong with you. If 你 can't stop stressing about it go ask a dermatologist. They'd have a better answer.
