Launched following His Royal Highness The Duke of Sussex's visit to The Scar Free Foundation Centre for Conflict Wound Research in March 2019, UNITS (Understanding Needs and Interventions For Treatment of Scarring) is the first study of its kind to assess the psychological impact of an altered appearance as a result of scarring and limb loss sustained during military conflict. We are working with veterans who have been seriously wounded during their deployment to develop tailored support materials to support them and their families adjust to life with a visible difference.
