Ever wondered what those little white spots that appear on your nails are? Well, forget what your grandma told you — it’s nothing to do with calcium deficiency.
It’s a discoloration known as punctate leukonychia, generally caused by something as simple as a knock or bump to the nail.
They form when the nail bed — where new nail cells are made — receives a trauma and ends up forming damaged nail cells. As the nail grows, the discolored nail tissue moves up your nail and slowly disappears.
