This study aims to examine the increasingly significant concept of sustainability in the beauty industry within a multidimensional framework encompassing environmental, social, and economic aspects. As a response to the environmental and ethical issues posed by conventional beauty practices, the sustainable beauty approach has emerged, shaped around principles such as the use of natural ingredients, fair supply chains, ethical production conditions, and eco-friendly packaging. The theoretical foundation of the research is built on the concepts of circular economy, green marketing, and ethical consumption. Employing a qualitative research method, this study analyzes the conceptual structure of sustainable beauty based on a comprehensive review of current academic literature and sectoral reports. Findings indicate that demand for sustainable products is particularly increasing among young consumers; however, high costs, lack of information, and trust issues regarding brands limit the widespread adoption of these products. The study emphasizes that for sustainable beauty to be adopted at a societal level, efforts should be made to enhance consumer education, implement transparent and reliable ethical certification systems, promote local production, and develop supportive public policies. In this context, sustainable beauty should be understood as a holistic approach that goes beyond individual preferences, closely tied to lifestyle choices, value systems, and broader societal transformation processes.
