Science
Mechanism of Action
This ingredient functions by forming an interface between immiscible oil and water phases, thereby stabilizing emulsions and preventing their separation. As a skin-conditioning agent and emollient, Glyceryl Sesquioleate contributes to the skin's barrier function, helping to bind moisture to the stratum corneum and impart a softer, more supple skin texture, while also improving the spreadability of topical products.
