Is it normal to eat your dead skin?
Depends.It depends
Lots of people chew or swallow little bits of dry skin, especially around their nails or lips. Eating a lot of it or picking until you’re sore is less harmless and may be worth addressing.
You’re not alone: plenty of people bite or pick at hangnails, chapped lips, or flaky skin and accidentally swallow some. A tiny bit now and then is generally no big deal, even if it’s not exactly a glamorous snack habit.
If you’re deliberately eating a lot, or you keep picking until you have sores, pain, or bleeding, that’s a different story. It may help to notice when you do it and keep your hands busy; if it feels hard to control or is damaging your skin, consider talking it through with a health professional.
