As the foundation of your skin care and anti-aging regimen, Liquid BioCell effectively supports the delivery and synthesis of collagen at the deeper layers of the dermis for long-term benefits.* CellProof Eye Cream and the rest of the Modere CellProof line do not replace Liquid BioCell (or vice versa), but are instead an ideal complement, delivering topical BioCell Collagen CG to the skin. When used together, the visibly lifting and firming effects of CellProof Eye Cream enhance the inside-out benefits of Liquid BioCell Life, Skin, Pure or Sport to the eye area. Because it is ingested, the benefits of Liquid BioCell reach the entire dermis from head to toe as well as the eyes, hair, skin, nails and connective tissues, including joint cartilage.* The benefits of CellProof Eye Cream and the rest of the CellProof line are limited to the external areas where they are applied.
