implications of scarring following injury or surgery, a doctor's key aim is to restore full function in a patient and help ensure they return to as close to their original state before their skin trauma or surgery. ensuring patients return as closely to their original appearance and original function is challenging in the context of scarring. scar-free healing is yet to be observed in healthy post gestational humans, despite being seen in human embryos. currently, it is only possible to reduce scar visibility, and the nhs suggests a number of different methods of doing this including corticosteroid injections, skin creams, silicone gels, pressure dressings, dermal fillers, radiotherapy and laser therapy. although these methods do reduce a scars visible appearance, they do not result in a scar free appearance. billions of pounds is spent on wound maintenance and healing on the nhs every year. between 2014 and 2015 in england and wales, 19,239 people sustained a burn injury which required hospital care. in addition to the significant financial cost, the cost of scars is immense to the patients too. one study into the quality of life of patients with scars found that over half of the participants felt stigmatised by their scars and felt their personal relationships deteriorated. in addition to this, 68% tried to hide their scars, whilst reporting their work life, self-confidence and ability to communicate with others had been negatively affected. future research and advances in scar-free healing could lessen the cost to the nhs whilst also improving the quality of life to many people affected.
