This wonderful blend of lipids has high levels of essential fatty acids (EFAs) to nourish your skin. Skin that lacks EFAs has less elasticity and more lines, roughness, and scaliness. Body Lipids protects your skin from the elements and transepidermal water loss (TEWL) — the moisture that evaporates from your unprotected skin. Moisture-rich skin functions better, looks softer, and feels smoother, so body Lipids contains crucial moisturizing oils: grapeseed, safflower, and sunflower.
