Science
Mechanism of Action
This ingredient functions by creating a breathable, hydrophobic film on the skin's outermost layer. This barrier prevents trans-epidermal water loss (TEWL) and shields the skin from environmental stressors. Due to its larger molecular weight, it remains on the surface, improving product spreadability and glide, while physically filling in fine lines and pores for a visibly smoother complexion.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed dimethicone and its related polymers, including Diphenylisopropyl Dimethicone, safe for use in cosmetics when formulated to be non-irritating. The FDA has further proposed classifying Dimethicone as a Category 1 ingredient (safe and effective) for skin protectant uses at concentrations up to 30%, indicating a high safety profile and low risk of irritation or sensitization.
