A young woman born with a huge mole covering half her face now has four egg-sized devices under her skin as she receives life-saving treatment to grow new tissue.

"During the first month of treatment, my face hurt so much because of the egg-sized expanders and the saline injections that I wanted to slam my face into a wall," Xiao said.
