Is it normal to eat your skin?
Depends.It depends
Chewing or swallowing a little loose skin, like a hangnail or flaky lip skin, isn’t unheard of. If you often pick or bite until you’re hurt, or feel unable to stop, it’s worth getting support.
If you mean chewing a hangnail, cuticle, or bit of flaky skin now and then, plenty of people do it—sometimes without thinking. Eating skin isn’t exactly a dinner-table habit, but a small amount of loose skin is usually not a big deal.
If you’re regularly picking or biting your skin, causing wounds, or feeling driven to do it even when you want to stop, that can be a hard-to-break habit rather than just an occasional quirk. Broken skin can get infected, so consider talking with a healthcare professional if it’s causing injuries or distress.
