2-Hexanediol is a humectant and preservative booster commonly used in skincare products to help retain moisture and extend shelf life. It works by drawing water into the skin while also enhancing the effectiveness of other preservatives, allowing brands to use lower amounts of traditional preservatives.
Benefits
Hydrates and moisturizes skin by drawing in water
Helps preserve products with lower preservative levels
Works synergistically with other skincare ingredients like niacinamide
Potential concerns
May cause cell viability concerns at concentrations above 1.0% in laboratory studies
Limited real-world safety data in humans at typical skincare concentrations (usually 2-5%)
Potential environmental concern if released into water systems
Science: While 2-hexanediol is widely used as a preservative substitute for parabens, recent cytotoxicity studies raise questions about safety at concentrations commonly found in skincare products (>2%). However, these findings are from laboratory cell studies and may not directly translate to human skin application. Further human safety studies are needed to confirm real-world risk.
Ceramide NP is a naturally-derived lipid that mimics ceramides found in healthy skin. It works to repair and strengthen your skin's protective barrier, helping it retain moisture and resist irritation.
Benefits
Restores skin barrier function and structural integrity
Reduces trans-epidermal water loss (helps skin stay hydrated)
Strengthens skin's natural defense against irritants and environmental stressors
Science: Recent research demonstrates that Ceramide NP effectively recovers damaged skin barrier function and can be formulated into advanced delivery systems (like ethosomes) to enhance skin absorption. Studies show it meaningfully lowers water loss while restoring epidermis structure in compromised skin.
