What Is Lauryl Dimethicone/Polyglycerin-3 Crosspolymer?

Lauryl Dimethicone/Polyglycerin-3 Crosspolymer is a silicone-derived ingredient created by chemically linking dimethicone (a silicone oil) with polyglycerin molecules. This crosslinking creates a larger, more structured molecule that behaves differently from simple silicone oils.

In skincare and haircare formulations, it functions as a conditioning agent and texture modifier. It deposits a thin, lightweight film on the skin's surface that can improve smoothness and create a refined feel, whilst also helping to control the viscosity and consistency of the product itself.

How It Works

The crosspolymer structure allows this ingredient to sit somewhere between a free-flowing silicone oil and a solid conditioning agent. When applied to skin, it deposits a smooth film that can help diffuse light and create a soft-focus visual effect, whilst also providing a light conditioning layer.

Because it's crosslinked rather than a simple fluid, it tends to stay where applied rather than migrating significantly across the skin, and may feel lighter than traditional silicone conditioning agents.

Clinical Evidence & References

Published clinical research specifically on this crosspolymer is limited. Evidence for silicone-based conditioning agents in general suggests they are well-tolerated and effective at improving skin texture perception and product feel. However, most data comes from cosmetic testing rather than dermatological studies.

Real-world tolerability appears good across skin types, though individual responses to silicone ingredients vary. Anyone with particular sensitivities to silicones should patch test first.

How to Use

This ingredient is typically found in formulated products rather than used as a standalone treatment. It works well in lightweight serums, primers, and foundations where a smooth, refined finish is desired. Layer it under or with other skincare products as directed by the specific formulation.

Safety & Precautions

Generally well-tolerated and considered safe for topical use in cosmetics. Those with silicone sensitivity or preference for silicone-free products should avoid it.
