Knowledge, Attitudes and Practices of Cosmetic Vendors Regarding Their Products, Skin Physiology and Dermatoses in Ouahigouya, Burkina Faso: A Ouahigouya, Burkina Faso: A Cross-Sectional Study

---

Résumé

Introduction. Cosmetic vendors play a crucial role in consumer guidance, yet their knowledge and practices remain poorly documented in sub-Saharan Africa. The lack of formal training and regulatory oversight raises concerns about product safety and appropriate recommendations. The objective was to assess the knowledge, attitudes, and practices of cosmetic vendors in Ouahigouya regarding their products, skin physiology, and dermatoses.
Methodology. A cross-sectional study was conducted from January to September 2023 among cosmetic retailers in Ouahigouya, Burkina Faso. Data were collected through face-to-face interviews using a structured questionnaire covering sociodemographic characteristics, product knowledge, commercial practices, and attitudes toward customers. Descriptive statistics were performed using Epi Info version 7.2.
Results. Sixty-four vendors participated (participation rate: 86.5%). The mean age was 30.6±10 years, with 57.8% females. Most vendors (95.3%) had no formal training in cosmetology. Only 20% could correctly define cosmetic products. While 84% recognized potential dermatological risks, 73% had adequate knowledge of skin barrier function. Product composition knowledge was inconsistent: only 16.7% (3/18) of recommendations for skin lightening and 27.3% (3/11) for acne treatment matched actual product formulations. Twenty percent of vendors created custom product mixtures. Only 20% directly referred clients to healthcare professionals for extensive or unidentified dermatoses. Conclusion. Cosmetic vendors in Ouahigouya demonstrate significant knowledge gaps regarding product composition, appropriate indications, and dermatological complications. These findings highlight the urgent need for structured training programs, strengthened market regulation, and enhanced collaboration with healthcare providers to improve consumer safety.
