Impact of Beauty Product Safety Education on Safe Cosmetic Use among Female Undergraduates in Nigeria

Abstract

Beauty product safety is an important public health concern because the widespread use of skincare products, makeup, hair-care products, fragrances, and other cosmetic preparations may expose users to harmful substances when products are counterfeit, expired, contaminated, improperly stored, or used incorrectly. Female undergraduates in Nigeria may frequently use beauty products because of personal grooming, social expectations, fashion trends, peer influence, social media, and advertising. However, limited knowledge of product ingredients, expiry dates, regulatory information, appropriate application, storage conditions, product authenticity, and possible adverse reactions may contribute to unsafe cosmetic use. Beauty product safety education provides an opportunity to improve students' knowledge of cosmetic safety and encourage safer purchasing, application, storage, and disposal practices. Against this background, this study investigates the impact of beauty product safety education on safe cosmetic use among female undergraduates in Nigeria. The study will be anchored on the Health Belief Model, Health Literacy Framework, and Social Cognitive Theory. The Health Belief Model explains how female undergraduates' perceptions of susceptibility to cosmetic-related health problems, perceived severity, perceived benefits of safe cosmetic use, perceived barriers, and cues to action may influence their cosmetic practices. The Health Literacy Framework emphasizes the ability to access, understand, evaluate, and apply information about beauty products and their potential health effects. Social Cognitive Theory emphasizes observational learning, peer influence, self-efficacy, reinforcement, and environmental factors in developing and maintaining safe cosmetic-use behaviours. Collectively, these theoretical perspectives provide a suitable framework for explaining how beauty product safety education may influence safe cosmetic use among female undergraduates in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise female undergraduate students aged 18 years and above enrolled in selected public and private universities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, universities, faculties or departments, levels of study, and eligible participants. Beauty product safety education will be assessed using indicators such as exposure to safety education sessions, frequency and duration of education, knowledge of cosmetic ingredients, product labels, expiry dates, batch information, storage requirements, product authenticity, regulatory information, appropriate application, recognition of adverse reactions, risks associated with sharing cosmetic products, patch testing where appropriate, and safe disposal of expired products. Safe cosmetic use will be assessed using indicators such as purchasing beauty products from reliable sources, checking product labels and expiry dates, verifying product information where applicable, avoiding suspicious or counterfeit products, following recommended application instructions, storing products appropriately, avoiding cosmetic sharing, discontinuing products when adverse reactions occur, seeking appropriate healthcare advice for persistent reactions, avoiding inappropriate combinations of cosmetic products, and safely disposing of expired or unwanted products. Data will be collected using structured questionnaires, standardized cosmetic-safety knowledge and practice assessment tools, cosmetic-use assessments, product-label information where available, and relevant university health programme records. Descriptive statistics will be used to summarize participants' characteristics, beauty-product use patterns, sources of cosmetic information, exposure to safety education, and safe-use practices. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of beauty product safety education on safe cosmetic use. Where a quasi-experimental design is adopted, safe cosmetic-use scores before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that beauty product safety education has a significant positive impact on safe cosmetic use among female undergraduates in Nigeria. Participants exposed to structured and practical beauty product safety education are expected to demonstrate safer cosmetic-use practices than participants without comparable exposure. Education may improve students' ability to read cosmetic labels, identify potentially harmful ingredients, check expiry dates, recognize suspicious products, understand appropriate storage requirements, and follow safe application procedures. Practical demonstrations may also improve students' ability to recognize signs of adverse reactions and encourage them to discontinue problematic products and seek appropriate healthcare advice. Education may discourage cosmetic sharing, unsafe product combinations, and the use of products obtained from unreliable sources. However, peer influence, social-media trends, beauty standards, aggressive advertising, affordability, desire for specific cosmetic outcomes, and widespread availability of unregulated or counterfeit products may reduce the effectiveness of education alone. The study therefore expects accessible, practical, evidence-based, and sustained beauty product safety education, supported by effective cosmetic regulation and consumer protection, to contribute significantly to improved safe cosmetic use among female undergraduates in Nigeria. The study is expected to contribute to the literature on cosmetic safety, beauty-product use, women's health, consumer health, health education, dermatological health, cosmetic-related adverse effects, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Agency for Food and Drug Administration and Control, universities, university health centres, pharmacists, dermatologists, public health practitioners, cosmetology professionals, student organizations, consumer protection groups, development partners, and policymakers regarding strategies for promoting safer cosmetic use among young women. The study will also provide evidence-based recommendations for integrating beauty product safety education into university health programmes, improving awareness of cosmetic ingredients and regulatory information, promoting safe purchasing and storage practices, strengthening recognition of cosmetic-related adverse reactions, encouraging appropriate healthcare-seeking, and improving consumer protection measures for beauty products across Nigeria.
