Amsterdam - Dermatologists have long been aware that superficial burns tend to heal quickly and leave little or no scarring, and that burns of full thickness, affecting deeper layers of the dermis, are often very slow to heal and leave permanent scars. According to Christopher Dunkin and Jonathon Pleat of the Stoke Mandeville Burns and Reconstructive Surgery Research Trust, Aylesbury, UK, the explanation for this difference might be that there is a "threshold level" for wound depth, with wounds above the threshold healing quickly without scarring and wounds below the threshold healing slowly and developing a fibrotic scar.
