Research published in The Lancet medical journal has revealed the test results on a new "spray-on skin" developed by scientists that could greatly improve recovery from chronic leg ulcers. The treatment might also benefit other types of chronic wound, such as ischaemic and diabetic foot ulcers.

In a study of 228 patients with venous leg ulcers, the spray was found to have accelerated healing and improved the chances of wound closure. The findings showed vastly improve recovery times and overall recovery from leg ulcers without the need for a skin graft:
Those receiving the most effective dosage were 52% more likely to see their ulcer clear up after three months than untreated patients. They also experienced a 16% greater reduction in wound area after seven days. In addition, the treatment helped wounds to close 21 days earlier.
Venous leg ulcers occur when high blood pressure in the veins of the legs damages the skin, causing it to break down. Individuals with restricted movement, obese individuals and those with varicose veins all face a greater risk of developing venous leg ulcers.

Standard treatment consists of compression bandages, infection control and wound dressings. However, this only heals between 30% and 70% of ulcers. And while skin grafts have been used, there's still a risk of causing further wound at the site from which the transplanted skin is taken.
