Knowledge, Pattern of Use and Outcomes of Eyelash Cosmetic Products among Women in Saudi Arabia: A Cross-Sectional Study

Objectives: Eye cosmetics such as eyeliners, eyelash extensions, contact lenses, and mascara are widely used for aesthetic purposes, yet improper or prolonged use may harm ocular health. This study aimed to evaluate the knowledge, practices, and self-reported ocular symptoms associated with eyelash and eyelid cosmetic use among a convenience sample of Saudi women. Methods: A cross-sectional survey was conducted between October 2024 and March 2025 among 448 women predominantly aged 18–24 years recruited via social media and online forums. Participants completed a structured questionnaire on demographics, cosmetic use, and ocular complaints. Data were analyzed using descriptive statistics and chi-square tests. Composite outcome variables (‘ocular complaints’) were defined as the presence of any self-reported symptom, including allergic reactions, lash thinning, itching, or discomfort. STROBE guidelines were followed for reporting observational studies. Handling of missing data: all questions were mandatory in Google Forms, preventing incomplete responses; remaining missing data were minimal (3 years. While 50.2% n = 225) reported no symptoms, others noted self-reported complaints such as allergic reactions (33.5%, n = 150), lash thinning (16.5%, n = 74), itching (22.8%, n = 102), and discomfort (21.4%, n = 96). Only 8.3% (n = 37) sought medical care. Awareness of potential risks was noted in 30.1%, Higher awareness was significantly associated with reduced periorbital irritation, swelling and rash around the eye, (p = 0.054) but did not consistently influence future use intentions among those prioritizing aesthetic outcomes. Unsafe practices, including prolonged reuse of eyelash extensions and inadequate makeup removal, were significantly associated with ocular complaints (p
