A wound arises when this barrier is breached, resulting in a loss of structural integrity and barrier function. An invisible wound represents a focal loss of human skin barrier function without any visible cut, ulcer, or defect. Despite appearing intact, the skin in these regions is functionally compromised. Current U.S. Food and Drug Administration (FDA) criteria define complete wound closure as full re-epithelialization without drainage or dressing needs, confirmed during two assessments at least 14 days apart. Wounds may satisfy this structural requirement for wound closure yet fail to restore barrier function. Recent studies demonstrate that wounds closed meeting FDA closure criteria but exhibiting elevated TEWL at the wound site (\n                    <jats:italic toggle=\"yes\">i.e.,<\/jats:italic>\n                    invisible wound) are more likely to recur, highlighting the clinical importance of achieving functional wound closure. Invisible wounds occur across the lifespan and arise from a wide range of everyday and high-risk exposures. They can result from age-related skin thinning, sunburn, and the routine use of cosmetic chemicals on vulnerable or sensitized skin. They may also develop after minor trauma that leaves no laceration, from mechanical stress imposed by prosthetic use, and from barotrauma or other subclinical mechanical forces commonly encountered by warfighters. Although outwardly undetectable, these silent disruptions weaken the skin\u2019s protective barrier, undermine systemic health, and contribute to chronic morbidity.\n
