Science
Mechanism of Action
Functioning as a substituted dimethicone, this ingredient operates by establishing a hydrophobic film on the stratum corneum, forming a protective surface barrier. This barrier actively reduces transepidermal water loss, thereby enhancing skin hydration, and offers a degree of protection against environmental stressors. Concurrently, its emollient action fills minute surface irregularities, promoting a visibly smoother skin texture.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that the broader category of dimethicone, methicone, and substituted-methicone polymers, to which this ingredient belongs, is safe for use in cosmetic products when formulated to be non-irritating. However, data were insufficient to assess safety for applications where incidental inhalation might occur, such as with airbrush devices.
