Skin Health Literacy in Ontario Secondary Schools: An Overlooked Opportunity for Preventive Health Education

Abstract

Skin conditions are among the most common health concerns in adolescence, with acne vulgaris affecting the majority of individuals between ages 12 and 24 years [1]. Atopic dermatitis, sun-related skin damage, and other inflammatory dermatoses also contribute substantially to morbidity during this developmental period [2]. Visible skin disease is associated with physical symptoms and psychosocial consequences, including reduced self-esteem, social withdrawal, anxiety, and stigma [3]. At the same time, adolescence is a critical window for establishing lifelong health behaviors such as sun protection, skin self-monitoring, and appropriate help-seeking, which influence long-term dermatologic outcomes including skin cancer risk [4].

Despite this burden, practical skin health education remains limited in secondary school curricula [5]. Instruction frequently emphasizes biological concepts without developing an applied understanding of skin disease prevention, recognition, and management. This disconnect raises concerns about whether current educational approaches adequately support adolescent skin health literacy.

Ontario's secondary science curricula illustrate this disconnect. Notably, students in Ontario are required to complete only two compulsory science credits, typically the Grade 9 and Grade 10 science courses, to earn an Ontario Secondary School Diploma [6]. Within this limited mandatory science curriculum, opportunities to develop practical skin health literacy remain limited. The 2022 Grade 9 Science curriculum introduces foundational biological concepts within a broader biology strand focused on sustainable ecosystems and environmental interactions but does not include learning expectations related to human skin or dermatologic health [7]. In Grade 10, students examine tissues, organs, organ systems, cellular organization, homeostasis, health-related technologies, and selected environmental effects on tissues [8]. Although the skin is discussed as part of human body systems and ultraviolet radiation is identified as a potential context for investigating tissue damage, the curriculum does not establish explicit competencies in recognizing common skin conditions, practicing sun safety, preventing skin disease, or identifying when a skin concern warrants medical assessment. Because these two courses represent the entirety of the compulsory science curriculum for most Ontario students, many may complete their formal science education without acquiring these essential skin health competencies. Because science is one of the few disciplines in which human biology is taught in a structured manner, these compulsory courses represent a unique opportunity to establish foundational skin health literacy for all students, regardless of whether they pursue further science education.

Accordingly, students are not expected to recognize common inflammatory or infectious conditions such as acne, atopic dermatitis, contact dermatitis, fungal infections, or scabies despite their high prevalence in adolescence. Nor is there structured instruction on identifying clinically important skin changes such as evolving pigmented lesions, asymmetry, or non-healing lesions, which are central to early detection of skin cancer. These omissions are notable because skin health literacy involves more than naming anatomical structures: it requires the ability to connect biological knowledge with prevention, recognition, and appropriate help-seeking.

In parallel, Ontario's Health and Physical Education curriculum similarly emphasizes nutrition, mental health, sexual health, injury prevention, and substance use [9]. Although these domains support preventive health, dermatologic health is not meaningfully integrated. The curriculum contains little explicit content on sun-protective practices, skin cancer prevention, common skin disorders, or the psychosocial effects of visible disease. Students can therefore complete secondary education with a strong general health foundation but limited preparation to make evidence-informed decisions about their skin.

The consequences extend beyond knowledge alone. Ultraviolet exposure during childhood and adolescence is a major modifiable risk factor for skin cancer, and early-life sunburns increase melanoma risk later in life [10]. Adolescents nevertheless frequently report inadequate sunscreen use and intentional tanning behaviors [4]. Limited dermatologic knowledge can also delay recognition of clinically important skin changes. Without awareness of warning signs such as evolving pigmented lesions or persistent inflammatory rashes, adolescents are less likely to seek timely medical care [11]. Misinterpretation of common conditions such as acne or eczema can delay effective treatment and compound psychosocial distress.

Visible skin conditions can also become targets for stigma. Misconceptions that acne reflects poor hygiene or eczema is contagious contribute to bullying, embarrassment, and social isolation [12]. These effects are particularly significant during adolescence, when peer perception strongly influences self-image. In the absence of structured education, adolescents often rely on social media and informal sources for skin health information. These platforms frequently propagate misinformation regarding skincare practices, tanning, and treatment [13], underscoring the need for evidence-based education in school settings.

Schools are widely recognized as effective environments for health promotion and preventive education and are well positioned to address these gaps. They reach most young people during a formative period and provide a population-level setting for preventive education [14]. School-based health programs have improved knowledge and behavior related to nutrition, physical activity, substance use prevention, and sexual health [15]. Evidence suggests that school-based dermatologic education is also effective. School-based programs have improved sun safety knowledge, attitudes, and behaviors [16]. Importantly, delivering standardized information in schools can further reduce inequities created by differences in family resources, health-care access, and exposure to reliable health information.

Improving skin health literacy does not require a separate course or major curricular restructuring but rather targeted integration within existing science and health frameworks. First, instruction on the integumentary system should extend beyond structure and function to include applied understanding of common adolescent dermatologic conditions. Conditions such as acne vulgaris, atopic dermatitis, contact dermatitis, and sun-related skin damage should be incorporated into learning objectives to support recognition, basic understanding, and differentiation between benign and concerning conditions.

Scabies provides a particularly rich example for interdisciplinary learning. Students could examine the biology and transmission of Sarcoptes scabiei, the challenges of clinical recognition, and measures used to interrupt spread [17, 18]. Such instruction would also illustrate how disruption of the skin barrier can lead to bacterial infection and serious renal or cardiac complications in some settings [17]. Including scabies alongside acne, eczema, and sun-related disease would broaden the curriculum from individual self-care to communicable disease prevention and collective responsibility.

Second, structured education on sun safety and skin cancer prevention should be explicitly embedded within health curricula. This should include evidence-based preventive behaviors such as sunscreen use, protective clothing, shade seeking, ultraviolet exposure reduction, and avoidance of indoor tanning.

Third, curricula should address psychosocial dimensions of skin health by correcting misconceptions and reducing stigma associated with visible skin conditions. Evidence-based discussion can normalize common disorders, foster supportive peer environments, and reduce psychosocial burden [19]. In addition, teaching should include critical appraisal of online skin-care claims so that students can distinguish credible health guidance from marketing and misinformation.

Finally, educational materials should reflect diversity in dermatologic presentation across skin tones. The underrepresentation of skin of color in medical educational resources can hinder recognition of disease in diverse populations [20, 21]. Inclusive images and examples are therefore essential to equitable and clinically relevant skin health education.

Table 1 contrasts current Ontario curriculum content with the practical skin health competencies that could be incorporated into existing learning expectations. Together, these recommendations provide a practical framework for integrating skin health literacy into existing science and health curricula while connecting foundational biology with prevention, recognition, help-seeking, health information literacy, and equity.

This commentary is based on an Ontario curriculum analysis, and its conclusions should not be interpreted as a comprehensive assessment of secondary education in all jurisdictions. However, similar gaps in adolescent skin health education have been identified in other settings where dermatologic literacy and sun safety education are not systematically integrated into school-based health curricula [5, 16, 22]. Skin health literacy remains an underrecognized component of adolescent preventive health education. Targeted integration into existing science and health curricula offers a feasible strategy to improve prevention, timely recognition, informed help-seeking, and equity without imposing substantial additional instructional burden. The graphical abstract summarizes the current curricular emphasis, the resulting gaps in applied skin health literacy, and the proposed areas for integration.

Secondary schools represent an underused opportunity to improve adolescent skin health literacy through targeted integration of practical dermatologic education within existing curricula. Strengthening school-based skin health education can promote preventive behaviors, improve early recognition of concerning skin changes, and reduce stigma surrounding common dermatologic conditions.
