What Is Lauryl Dimethicone?
Lauryl dimethicone is a silicone-based conditioning ingredient derived from dimethicone, a polymer created through the combination of silicon and oxygen. It belongs to a class of ingredients known as silicones, which have been used in skincare formulations for decades due to their stability and cosmetic properties.
In skincare products, lauryl dimethicone functions as a skin conditioning agent. It works by forming a protective layer on the skin's surface, which can help reduce moisture loss and support the skin's natural barrier. This type of ingredient is commonly found in barrier-repair formulations and products designed to protect skin from environmental irritants.
How It Works
Lauryl dimethicone creates an occlusive layer on the skin's surface. Occlusive ingredients work by sitting atop the stratum corneum (the skin's outermost layer) and forming a physical barrier that slows transepidermal water loss. This helps the skin retain its natural moisture.
By maintaining hydration and shielding the skin from external irritants and moisture, this ingredient can support the skin's barrier function—particularly important when the skin is compromised or irritated. Unlike some heavier occlusives, silicones like this one are typically lightweight and non-comedogenic.
Clinical Evidence & References
Research on dimethicone-based protectants suggests they offer meaningful barrier-supporting properties. Studies comparing skin protectant formulations, including those containing silicone derivatives, have demonstrated their efficacy in reducing irritation from known irritants such as sodium lauryl sulphate and in maintaining skin hydration when applied to compromised or irritated skin.
However, evidence specific to lauryl dimethicone alone is limited. Most research has focused on broader silicone-based protectant products rather than this ingredient in isolation. Current evidence supports its use as part of a barrier-repair formulation, though individual results may vary depending on the overall formula and skin condition.
How to Use
Lauryl dimethicone is typically used as a supporting ingredient within a broader formulation rather than a standalone treatment. Look for it in barrier creams, protective moisturisers, and products designed for sensitive or irritated skin. It can be used daily as part of your routine, often in the evening or whenever extra barrier support is needed. It works well in combination with other hydrating and skin-conditioning ingredients.
