A partial face transplant has been successfully completed on a woman in France.
The 38-year-old needed a new nose, chin and mouth after her lower face was injured by a dog.
Doctors say the woman will not look exactly like she did before but will have a mixture of her old face and that of her donor.
Doctors say the patient is "in excellent condition" but has chosen not to reveal her identity.
Face transplants have not yet been given the go ahead in the UK as some people are worried they're not a good idea.
There are concerns that some people wouldn't be able to handle looking like a different person.
The woman who received the first face transplant had lots of counselling before her operation to prepare her for the end result.
She will now have to take lots of drugs to make sure her body accepts her new features.
