Cleansers, Moisturizers, and the Skin Barrier

Recent research on polymeric surfactant–based cleansers demonstrates significant benefits for individuals with sensitive skin. Key skin barrier parameters such as erythema, irritation, peeling, roughness, and dryness showed no increase during use. Objective measurements including transepidermal water loss, skin pH, and corneometry remained stable, indicating that the skin barrier was preserved. Additionally, these cleansers did not disrupt the skin microbiome or alter natural moisturizing factors and lipid markers. This comprehensive data package, combining both self-reported sensory improvements and mechanistic skin evaluations, supports the safety and efficacy of these novel cleansers for sensitive skin.

When selecting cleansers for sensitive or compromised skin, important considerations include maintaining an appropriate pH to protect the acid mantle and choosing mild surfactants that do not strip essential lipids. Incorporating moisturizing ingredients such as humectants and lipids can further support the skin barrier. Cleanser options that combine these qualities while also delivering a pleasant sensory experience—like abundant foaming—encourage patient adherence, which is often a challenge when patients reject mild but less enjoyable products. The integration of polymeric surfactants in cleansers offers a balance between effective cleansing and gentle care, making them suitable for a wide range of patient needs, including those with eczema, rosacea, or postprocedural sensitivity.

Moisturizers play a crucial role in restoring skin health by replacing lipids lost during cleansing, enhancing hydration, reducing water loss, and improving overall skin appearance. Key ingredients such as ceramides, cholesterol, fatty acids, natural moisturizing factor mimics, hyaluronic acid, and glycerin are essential for maintaining skin barrier function. Educating patients on the importance of moisturizing, especially those with acne or aging skin who may underestimate their hydration needs, is vital. With a diverse array of formulations available, it is possible to find products that suit individual preferences, ensuring that all patients can maintain optimal skin health through proper cleansing and moisturizing routines.
