All studies were critically appraised using Cochrane\u2019s Risk of Bias in Non-Randomized Studies of Interventions and the Risk of Bias Tool for Randomized Trials (second version) tools.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Murine model data suggest DHA may provide minimal photoprotection, insufficient to replace sunscreen, and may delay ultraviolet radiation-linked tumor development. Patients with erythropoietic protoporphyria (EPP) and vitiligo may benefit from DHA. No link has been established between DHA and clinically relevant vitamin deficiency and contact dermatitis. Concerns remain about cutaneous free-radical formation and product absorption. DHA\u2019s use in psoralen-UVA therapy does not warrant further development. DHA\u2019s role in altering the evaluation of melanocytic lesions with dermoscopy is minor.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>DHA may have some use in patients with vitiligo and EPP. No studies demonstrated harm related to DHA use, though most studies were low-quality, conducted on a few humans or animals, occasionally with product concentrations over the threshold permitted by the European Commission.
