In particular, regarding psoriasis, vitiligo, and lichen planus, excess reactive oxygen species and a decline in endogenous antioxidant systems are observed. In this regard, treatments with antioxidant properties could be appropriate therapeutic options. To date, clinical trials in dermatology on these treatments are limited. We reviewed the available studies on the efficacy of antioxidant therapies in psoriasis, vitiligo, and lichen planus. The role of herbal derivatives, vitamins, and trace elements was analyzed. The antioxidant properties of conventional therapies were also evaluated. Data from the literature suggest that antioxidants might be useful, but available studies on this topic are limited, heterogeneous, not completely standardized, and on small populations. Furthermore, in most cases, antioxidants alone are unable to induce significant clinical changes, except perhaps in mild forms, and must be used in conjunction with standard drug treatments to achieve measurable results. Further studies need to be conducted, considering larger populations and using internationally validated scales, in order to compare the results and clinical efficacy.<\/jats:p>","DOI":"10.3390\/antiox10071087","type":"journal-article","created":{"date-parts":[[2021,7,6]],"date-time":"2021-07-06T11:36:44Z","timestamp":1625571404000},"page":"1087","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Therapies with Antioxidant Potential in Psoriasis, Vitiligo, and Lichen Planus"],"prefix":"10.3390","volume":"10","author":[{"given":"Fabrizio","family":"Guarneri","sequence":"first","affiliation":[{"name":"Department of Clinical and Experimental Medicine, Dermatology, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1851-2242","authenticated-orcid":false,"given":"Lucrezia","family":"Bertino","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, Dermatology, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8089-7449","authenticated-orcid":false,"given":"Giovanni","family":"Pioggia","sequence":"additional","affiliation":[{"name":"Institute for Biomedical Research and Innovation (IRIB), National Research Council of Italy (CNR), 98164 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5436-1501","authenticated-orcid":false,"given":"Marco","family":"Casciaro","sequence":"additional","affiliation":[{"name":"School and Unit of Allergy and Clinical Immunology, Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastiano","family":"Gangemi","sequence":"additional","affiliation":[{"name":"School and Unit of Allergy and Clinical Immunology, Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1049","DOI":"10.1016\/j.jaci.2019.10.015","article-title":"Epigenetic factors involved in the pathophysiology of inflammatory skin diseases","volume":"145","author":"Weidinger","year":"2020","journal-title":"J.
