With baby boomers hitting retirement age, many are concerned about the ravages of ageing-aching joints, difficulty walking, as well as the time-worn wrinkles on their skin. Now there's a supplement that can be taken orally, used as a skin cream, or injected directly into aching joints that can help turn back the clock. Hyaluronic acid, a natural substance manufactured by the body and distributed throughout our connective tissue, can absorb over 3,000 times its weight in water, enabling it to hydrate and cushion dry joints, with the bonus of hydrating the collagen in our skin, smoothing out wrinkles, and bringing back the glow of youth.
