Scarring occurs at a critical depth of skin injury: precise measurement in a graduated dermal scratch in human volunteers.

Background: The association between scarring and the depth of dermal injury or burn is clinically recognized but not quantified. The authors tested the hypothesis that there is a critical depth beyond which a fibrous scar develops.

Methods: A novel jig produced a wound that was deep dermal at one end and superficial dermal at the other.

Topical radiant heating in wound healing: an experimental study in a donor site wound model*.

The importance of temperature in the wound-healing process is rapidly being recognised as a novel way in which to manipulate the wound-healing environment. In this study, we aimed to investigate the direct effect of topical radiant heating (TRH), using a novel bandaging system (Warm-Up, Arizant Health care Inc., Eden Prairie MN, USA; Augustine Medical, USA), on wound healing at a physiological and cellular level.
