Input: A mother and her daughter who both have a rare condition which makes their skin wrinkle prematurely have undergone matching £50,000 facelifts. Tracey Gibson, 45,  and her daughter Zara Hartshorn, 18, both suffer Lipodystrophy, a rare condition which makes fat dissolve beneath tissue. While Zara had a face-lift at the age of 16 to stave off bullies, her mother has long suffered lingering stares and cruel nicknames. Having been rejected by the NHS for a free operation, the mother of seven thought she would be forever trapped in a sinking face. But, two years since her daughter received free surgery from American doctors, the 45-year-old has unveiled her new £50,000 face after being flown overseas to receive the same VIP treatment.Tracey Gibson and her daughter Zara Hartshorn both suffer LipodystrophyThe rare condition makes fat dissolve beneath tissue and wrinkles skinZara, now 18, was offered free treatment in the U.S. when she was 16Her mother, 45, was rejected by the NHS when she asked for a faceliftAmerican doctors have since treated her to the same deal as her daughterFace and neck lift as well as multiple Botox treatments were worth £50,000
