Lip skin presents unique formulation challenges due to its distinct anatomical structure - with only 3-4 epithelial cell layers compared to 16 layers elsewhere, no sebaceous glands, and high rates of transepidermal water loss reaching 30 g/m²/hr in clinical measurements. These characteristics make lips particularly susceptible to environmental stressors and dehydration.

The core challenge lies in developing delivery systems that can maintain sustained moisturization while accommodating the constant mechanical stress and environmental exposure that lips experience throughout the day.

This page brings together solutions from recent research—including dual liposome systems for controlled delivery, water-oil emulsion matrices with specialized botanical extracts, amphiphilic compound-based moisturization mechanisms, and synergistic blends of humectants with repair actives. These and other approaches focus on achieving extended-release hydration while maintaining stability and sensory properties suitable for lip applications.
