I have it on my nails too!

What exactly is this black line? Is it a sign of health problems? Many people have such concerns.

In this regard, Bao Xiulan, chief physician of pediatrics at Peking Union Medical College Hospital, published a popular science article:

The black line on the nail is called the black line of the nail, which is a common symptom of the nail matrix nevus. You can understand it as: a pigmented nevus growing in the nail.

Generally speaking, there is a very small chance that the nail matrix nevus will turn into melanoma, so don’t panic too much if black lines appear on your nails, but don’t ignore it easily either. You should closely observe the changes in the black lines.

If you find that the width of the black line exceeds 3mm, spreads to the skin, and the color is uneven, you should be careful as it may be related to melanoma and you need to seek medical attention immediately.

Some netizens also shared their own pictures after the treatment. "My nails two years after the surgery. Whenever I see them, I remember the heart-wrenching pain when I changed the dressing."
