Cosmetic use among preteens and adolescents is increasingly common, fueled by social media trends and marketing campaigns that blur the lines between childhood innocence and adult beauty culture. Although these products are often marketed as safe, many contain chemicals of concern, including endocrine-disruptions agents, allergens, and potential carcinogens. Early and prolonged exposure during critical stages of growth raises important questions about immediate and long-term health consequences. Children and teenagers are particularly vulnerable because their skin barrier is thinner and more permeable than that of adults, allowing greater absorption of harmful substances. Endocrine-disrupting chemicals interfere with normal hormonal pathways, potentially altering physical development and reproductive health. Fragrances and preservatives may provoke allergic or irritant reactions, leading to dermatologic conditions such as contact dermatitis and acne exacerbation. Cumulative exposure over years may also increase the risk of cellular damage or malignancy. Beyond physical effects, cosmetic use during adolescence carries psychosocial implications. Engagement with appearance-focused products reinforces unattainable beauty ideals, heightens self-consciousness, and may increase anxiety, body dissatisfaction, and eating-disorder behaviors. These risks are amplified by advertising practices that emphasize perfection while concealing potential harms. Strengthening regulation, ingredient transparency, age-specific safety testing, and public health education is needed to safeguard adolescent well-being.
