Why it’s built this way
Bio H.A. Firm & Flex is built around one molecule doing two jobs: hyaluronic acid is native both to the synovial fluid that cushions joints and to the matrix that holds water in skin, and the body makes less of it with age. MDR chose FlexLuron low-molecular-weight hyaluronic acid for the formula — a single molecule of H.A. can hold many times its weight in water, which is the point of getting more of it.
