Science

Mechanism of Action

Polyglyceryl-3 Dimethicone, often referred to more precisely as Polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone, exerts its primary action by forming a thin, occlusive yet non-comedogenic film on the skin's surface. This barrier effectively minimizes transepidermal water loss (TEWL), thereby locking in moisture and sustaining the skin's natural hydration balance. It also acts as a protective shield against various environmental aggressors such as pollutants and harsh weather. Additionally, it functions as a humectant, drawing moisture into the skin. As a sophisticated silicone emulsifier, it stabilizes water-in-oil and water-in-silicone systems, while simultaneously refining product texture, optimizing spreadability, and potentially enhancing the dermal absorption of other active compounds.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that dimethicone and its related polymers are safe for use in cosmetic products, attributing this to their substantial molecular weights which limit skin absorption. Regulatory bodies in the European Union and the U.S. Food and Drug Administration (FDA) also recognize its safety, particularly at recommended usage levels. While generally considered safe with a low propensity for irritation or allergic reactions, patch testing is advisable for individuals with particularly sensitive skin types.
