What Is Phytantriol?
Phytantriol is a naturally derived alcohol belonging to a class of lipids known for their ability to form liquid crystal structures. It functions primarily as a humectant, meaning it attracts and binds water to the skin surface, helping to improve hydration levels.
Beyond basic moisture-binding, phytantriol has gained research attention as a skin permeation enhancer—a substance that can improve how other ingredients penetrate the stratum corneum, the skin's outermost barrier. This dual role makes it useful in formulations where enhanced delivery of actives is desirable.
How It Works
Phytantriol operates as a humectant by forming hydrogen bonds with water molecules, effectively drawing them into the outer layers of skin. This hygroscopic property helps increase skin hydration and can improve skin texture and appearance.
In certain formulations, phytantriol can self-assemble into liquid crystal structures (cubic or hexagonal phases) that create pathways through the stratum corneum. This structural organisation may allow other active ingredients to penetrate more efficiently than they would in conventional vehicles, though this benefit is most relevant in specifically engineered formulations rather than simple moisturisers.
Clinical Evidence & References
Research supports phytantriol's role as a humectant and confirms its use in cosmetics at concentrations up to 1% is well-established. Studies demonstrate that when incorporated into liquid crystal-based systems, phytantriol can enhance the skin permeation of hydrophilic (water-loving) drugs in both animal models and human skin samples, suggesting potential value in delivery systems for active ingredients.
However, most evidence for enhanced permeation comes from specialised formulation studies rather than consumer skincare products. In standard skincare formulations, phytantriol functions primarily as a straightforward humectant. Further research would help clarify its performance benefits in typical moisturisers and serums at cosmetic concentrations.
How to Use
Phytantriol is typically incorporated into formulations by manufacturers rather than used as a standalone ingredient. It works well alongside other humectants like glycerin or hyaluronic acid and does not require specific timing or layering protocols. In serums and moisturisers, it is used at concentrations generally below 1%, so there is no need for special precautions regarding frequency or duration of use.
