Deconstructing the Formulation of an Effective Natural Cream
A superior cream is a delivery system governed by chemistry. Hydration comes from humectants like plant-derived glycerin and sodium hyaluronate, which bind water via hydrogen bonding, and occlusives like shea butter (Butyrospermum parkii), rich in unsaponifiables (triterpenes, sterols) that reinforce the skin’s lipid matrix. Protection involves antioxidants: pomegranate contains punicalagins, ellagitannins with demonstrated ability to inhibit UVB-induced collagenase (MMP-1) and protect fibroblasts. Sea buckthorn is unique for its palmitoleic acid (omega-7) content, a component of skin sebum, and its high tocopherol/tocotrienol profile. Barrier Support is achieved through phytoceramides (from wheat, rice) and cholesterol-like phytosterols that integrate into the stratum corneum lamellae, improving cohesion and reducing transepidermal water loss (TEWL). The vehicle matters as much as the actives.
