Research Progress and Applications of Surfactants for Sensitive Skin

Sensitive skin, affecting nearly half of the global population, is characterized by heightened reactivity to environmental and cosmetic stimuli, leading to discomfort and a compromised skin barrier. Surfactants, essential components in skincare products, play a significant role in both the irritation and protection of sensitive skin due to their interactions with the skin’s lipid layers. This paper explores the characteristics of sensitive skin and the impact of various surfactants—anionic, cationic, amphoteric, and non-ionic—on skin health. Advancements in surfactant design, including natural surfactants, green chemistry approaches, and molecular modifications, are discussed to highlight their potential in reducing irritation and enhancing skin compatibility. The study concludes that surfactant innovation, driven by molecular design and the incorporation of environmentally friendly processes, holds great promise for developing high-quality products that meet the specific needs of sensitive skin while promoting sustainable development in the cosmetics industry.
