 The investigators will conduct a randomised controlled trial to compare the efficacy of an adapted form of an existing self-help intervention with an enhanced version of the same intervention that incorporates if-then planning instructions or implementation intentions and a control condition that will receive support as usual. Participants who self-identify as having a visible condition affecting the skin or hair, or scarring to the skin that negatively affects their social confidence will be allocated to one of three conditions: augmented self-help, standard self help or control. The interventions will be delivered online and participants will complete psychometric outcome measures at two time points, four weeks apart.
