"Do you have ferritin face?" a young woman asks on TikTok, pointing to dark circles, washed-out skin and brittle hair, alongside before-and-after style photographs. The content creator puts these features down to her iron levels.

It is one of a growing number of videos and posts on TikTok and Instagram claiming that low ferritin - a protein which stores iron in the body - can leave visible clues on your face.
