Diisostearoyl Polyglyceryl-3 Dimer Dilinoleate

Diisostearoyl polyglyceryl-3 dimer dilinoleate is a synthetic emollient derived from glycerin and fatty acids. It functions as a skin conditioning agent, designed to soften the skin surface and help lock in moisture.This ingredient belongs to a class of polyglyceryl esters commonly used in skincare and cosmetic formulations. Its molecular structure allows it to form a protective layer on the skin without leaving a heavy residue, making it suitable for lightweight moisturisers and serums.

This ingredient works by forming a thin, occlusive layer on the skin's outer surface. This barrier reduces water evaporation from the epidermis, allowing skin to retain moisture more effectively. Unlike heavier oils, its molecular size and structure allow it to absorb into the outer layers without creating a greasy feel.

This ingredient is typically incorporated into formulations by the manufacturer rather than used as a standalone product. When selecting a moisturiser or serum containing this ingredient, apply to clean, damp skin to maximise moisture absorption. A little goes a long way; start with a pea-sized amount and adjust as needed based on your skin's response.

Generally well-tolerated across skin types. Some individuals may experience sensitivity if applied in excessive amounts; discontinue use if irritation occurs.
