I have been to the doctor and the dermatologist, and nobody knows what this could be caused by.
I have a brownish yellow discoloration around my mouth and on my eyelids. I'm not sure how long I've had it, but I started noticing it around 5 years ago. It isn't a surface stain that can be scrubbed off, and the texture of the skin is normal. I'm a 20 year old female.
I've had blood work done, and there is nothing wrong with my liver, thyroid, or iron levels.
This is what the area around my mouth looks like.
