I have lentigo simplex. The lentigo on my skin doesn’t really have an affect on anything. I’ve had it since I was a kid, so I don’t really notice it as being anything different. Most people think they are freckles when they see mine.
I have been to a dermatologist, too. He found nothing wrong. It’s nice to hear it reaffirmed that lentigo simplex is not an indication of a systemic disease.
