Using the new technique, researchers at the University of Pennsylvania were able to create colour-coded heat maps showing the results of Botox. Before injection (bottom left), the light blue in the center reveals the compression of the skin between the eyebrows and above the nose. Two weeks after injection (bottom right), the new colours show less stretch in the muscles. The top left image shows horizontal stretch in the forehead before injection. The top right shows how the stretch of the forehead is reduced, as shown by light blue.

Lucy Wilson, from Derby, was given just 24 hours to live after she was scalded by hot bathwater on the day before her first birthday. The university student (pictured today and inset as a baby) has since undergone dozens of procedures to correct the burnt skin on her hands, feet and right leg, and had four fingers and toes amputated in a bid to save her life. Miss Wilson said she now feels confident enough to wear bikinis and summer clothes - and that she hopes her decision will show other burns survivors that they don't need to 'hide themselves away'.

Katie Green (pictured) was 15 when she was given the human papillomavirus jab. Shortly after her first shot of Cervarix Katie's arm began to swell, then after the second jab she became dizzy, nauseous and generally unwell. At 15, Katie had been flying high academically, played cricket for Worcestershire and joined trials for the England women's junior rugby squad (left and inset). Today, aged 20, it's a different story. Katie's mother (far right) says her daughter's health has always been robust and she thinks the jab has damaged her nervous system.

Angie Barlow, 48, from Altrincham, Greater Manchester, became scared of the dentist after her mother's throat cancer was discovered when she had a tooth removed. For ten years, whenever Ms Barlow's teeth fell out, she would stick them back into her mouth with superglue. Eventually, the toxic chemicals in the glue meant she lost 90 per cent of the bone supporting her teeth in her upper jaw, and she was forced to spend her life savings on treatment. Dentists had to remove most of her teeth, insert titanium pins into her mouth in order to screw on false teeth and restore her smile. Now, after having the operation, she says she feels 'wonderful'. She said: 'People have said they notice a difference in me. My friends, they're just like "oh my God, you're more outgoing".'

Jordan Hawthorne, of Plymouth, Devon, had a seizure after smoking Vertex (inset), a new substance freely available from high street shops. After doctors managed to save his life, Jordan and his family are now calling on the Government to bring forward a blanket ban on legal highs.

Beth Clemison, 27, from Llanfyllin, Powys, became worried when her unborn son Theo wasn't moving as much as usual when she was 35 weeks pregnant. She was examined twice and told not to worry as Theo's heart rate was normal. But Mrs Clemison felt sure something was wrong, and was so insistent doctors agreed to give her an ultrasound. The scan revealed the protective amniotic fluid around Theo had drained away, and she was rushed for an emergency C-section to save his life (Theo is pictured with his mother after his birth, left). Now both Mrs Clemison and Theo, now eight months old, are doing well, but she credits her maternal instinct with saving her son (the pair are pictured, right).

Preston North End supporter Linda Moon (pictured, left, in hospital and, right, with player Kevin Davies) claimed to be suffering from incurable blood and bowel cancer - and described how she had planned her own funeral. But the 34-year-old has now confessed to continuously lying about her health after rumours began to circulate on social media. Preston player Davies, whose parents both died of cancer, went on Twitter to say he felt 'deceived and saddened' after hearing her admission (tweet inset).

Terrified of being a bald bride, Ellie Baker, 35, from Plymouth, was forced to use clever hair extensions to cover gaping bald patches after her hair began falling out in clumps. Months before the couple's wedding day Mrs Baker started to notice clumps of hair falling out in the shower. As her condition worsened and she was left with large bald patches, doctors diagnosed her with alopecia areata. The mother-of-three, said: 'I was very worried, I did not want to lose my hair. I have always had long lovely hair so the thought of losing it was awful. I didn't want to be a bald hairdresser, but I especially didn't want to be a bald bride.'

Hayley Keane, 26, of Hartlepool, believes her baby, Simon, who died at just three days old, could have been saved if she had a routine screening for the Group B Streptococcus, a bacteria in the vaginal-rectal area. The mother-of-two, from Hartlepool, is now campaigning for the NHS to introduce routine screenings, that exists in countries such as France, Spain and the US.

Georgia Marrison, 18, (right) from Rotherham died of stomach cancer after doctors said she was only losing weight because she 'wanted to be a stick insect'. Her weight plummeted by two stone and she was consistently vomiting and falling ill, but medics told her worried family the symptoms pointed to severe anaemia. The aggressive cancer went undiagnosed for five months and when she was eventually admitted to hospital, doctors found she had cancer in her eye and ovaries and she had contracted meningitis. Now her mother Joanne (pictured together left) is calling for 'Justice for Georgia' in an effort to alert other parents to the warning signs of cancer in teenagers.

'His unselfish act has saved my life....he is my hero.'
