Both glycerin and hyaluronic acid are generated in skin cells and utilized to keep skin moisturized. Glycerin draws moisture into the skin, medium molecular Hyaluronic Acid improves hydration in the epidermis's outermost layer - where fine lines and winkles form - and low molecular Hyaluronic Acid penetrates deeper into the epidermal layers, stimulating the skin's own production of Hyaluronic Acid and replenishing moisture where deeper wrinkles form.
They are important elements in the Eucerin Hyaluron-Filler Moisture Booster product, providing skin with a fast and powerful moisture boost, as well as increasing skin hydration for up to 24 hours.
