Science
Mechanism of Action
This branched MQ silicone resin utilizes C16 cetyl chains to anchor onto the skin, forming a cohesive but flexible film. It functions by sealing in moisture to reduce transepidermal water loss (TEWL) while simultaneously providing a durable matrix that holds pigments and UV filters in a uniform distribution, preventing migration and enhancing wear-time.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Concentrations between 1-10% demonstrate significant reductions in pigment transfer and enhanced film durability for long-wear applications.
- 02 Usage at 2-5% has been shown to optimize the SPF performance of both mineral and chemical sunscreens by ensuring more consistent film coverage.
Transparency
Dusting Analysis
As a functional film-former, concentrations below 1% typically fail to provide the structural integrity required for waterproof or long-wear claims. It is rarely used as a 'marketing-only' ingredient due to its specific formulation benefits.
