© Mibelle Biochemistry, Switzerland 2007 Résumé Trimoist- the 3-step moisturizing system supports all three elements of the skin's own moisture balance system: 1. Protecting film CM-Glucan enhances the skin's own defence system and builds a superior protecting film. 2. Lamellar Lipid barrier Skin-like Lamellar Lipids enhance the barrier function of the lipid layer in the epidermis to boost the moisture barrier. 3. Humectants Glycerin and Lactate mimic the Natural Moisturizing Factor (NMF) of the skin to provide an instant burst of hydration.  Carnosine prevents the cross-linking and stiffening of collagen by glycation - the technical term for the process that leads to a loss of skin-elasticity
