Abstract
BACKGROUND: Social media is used as a tool for information exchange, entertainment, education, and intervention. Intervention efforts attempt to engage users in skin health. OBJECTIVE: This review aimed to collect and summarize research assessing the impact of social media on skin health promotion activities undertaken by social media users. METHODS: In accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines, the following scientific databases were searched: Scopus, Web of Science, PubMed, Academic Search Ultimate (via EBSCO), Academic Research Source eJournals (via EBSCO), ERIC (via EBSCO), Health Source: Consumer Edition (via EBSCO), and Health Source: Nursing/Academic Edition (via EBSCO). Using ProQuest Dissertations and Theses, OpenGrey, Grey Literature Report, and MedNar, the search was supplemented with gray literature. Articles on skin care, skin health, skin diseases, skin protection, and educational activities promoting healthy skin on social media were selected for review (search date: February 6, 2023). The following qualification criteria were used: original research; research conducted on social media; and research topics regarding educational activities in skin health promotion, skin care, skin health, skin diseases, and skin protection. To assess the risk of bias, the following tools were used: the Cochrane Collaboration tool for risk-of-bias assessment (randomized controlled trials and quasi-experimental studies) and the Centre for Evidence-Based Medicine checklist (cross-sectional studies). RESULTS: Altogether, 1558 works were considered, of which 23 (1.48%) qualified, with 3 (13%) studies on acne and 20 (87%) on skin cancer, sunscreen, and tanning. Social media interventions were dealt with in 65% (15/23) of the studies. The review made it possible to investigate cognitive and cognitive-behavioral interventions. In both observational and interventional studies, the most frequently discussed topics were skin exposure and protection against UV radiation and skin cancer. The analyzed research showed that social media is a source of information. Visualization has a strong impact on users. The involvement of social media users is measured through the amount of content shared and contributes to changing attitudes and behaviors regarding skin health. CONCLUSIONS: This review outlined the impact of social media, despite its heterogeneity, on users' skin health behaviors, attitudes, and actions. It identified strategies for digital interventions to promote skin health. In health sciences, a standardized tool is needed to assess the quality of social media digital interventions. This review has several limitations: only articles written in English were considered; ongoing studies were omitted; and there was a small number of interventional studies on acne and a lack of research on daily skin care, education, and antiaging activities on social media. Another limitation, resulting from the topic being too broad, was a failure to perform quantitative data analysis, resulting in the studies that qualified for the review being heterogeneous.
