Dimethicone/Polyglycerin-3 Crosspolymer

Dimethicone/Polyglycerin-3 Crosspolymer is a synthetic silicone-based polymer created by chemically cross-linking dimethicone (a silicone oil) with polyglycerin-3. This creates a three-dimensional network structure that sits somewhere between a pure oil and a thickening agent.In skincare formulations, it functions as a multitasking ingredient: it helps emulsify (blend oil and water), conditions the skin surface, controls viscosity (thickness), and can absorb excess moisture. It appears in roughly 0.1% of skincare products, often in cleansers, moisturisers, and serums where formula stability…

The crosspolymer structure allows this ingredient to sit at the interface between oil and water phases in a formulation. Its dimethicone backbone provides a conditioning feel, whilst the polyglycerin component helps it integrate with both hydrophobic (oil-loving) and hydrophilic (water-loving) ingredients. This dual nature makes it an effective emulsifier and viscosity controller.On skin, it deposits a light conditioning layer that improves smoothness and tactile feel without the heaviness of traditional silicone oils. Because it's polymeric (a long-chain molecule), it doesn't penetrate dee…

This ingredient works behind the scenes in finished products; you don't need to use it differently based on its presence. It's most beneficial in formulations designed to improve texture and stability. If you use products containing this polymer alongside other actives, application order remains unchanged—this ingredient doesn't interact significantly with common skincare actives.

Generally well-tolerated across all skin types. As a silicone-based polymer, it remains largely on the skin surface and is not systemically absorbed. Those avoiding silicones for personal or environmental reasons may wish to check ingredient lists.
