The skin barrier depends on a balanced environment of water, lipids, and surface protection. When the barrier feels depleted, a lipid-forward cream can support softness, comfort, and moisture retention.
Bio-compatible lipid design refers to the use of oils, butters, wax esters, and lipid components that support softness, glide, and barrier comfort without relying on a generic emollient system.
Occlusive ingredients form a protective surface layer that supports moisture retention. In a facial cream, occlusion should be balanced with humectants, emollients, and elegant texture.
Transepidermal water loss, often abbreviated as TEWL, describes water leaving the skin through the epidermal surface. A barrier-supportive cream should address both sides of the equation: humectant hydration and lipid-rich moisture retention.
A facial cream containing water requires preservation. Preservation is not a compromise; it is a formulation requirement for product integrity during normal consumer use.
