In some people, it’s well defined, especially around the thumbs. In others, it seems almost absent—a detail that, in the majority of cases, is nothing abnormal. It even tends to fade with age or in children, without this indicating a health problem. In reality, the appearance of the lunula varies depending on the individual, their skin tone, their genetics… and sometimes even the ambient light.
So no, a barely visible lunula isn’t a cause for alarm in itself. It’s rather its evolution over time, or the sudden appearance of abnormalities, that can be cause for concern—as long as the whole picture is examined.
