Loss of firmness and volume alongside wrinkles make ageing skin look even older. Our jowls droop, our features crumple, our cheeks hollow out and our mouths look down-turned. These changes in volume can make us look old and grumpy. Hormonal fluctuations, lifestyle and the natural ageing process are to blame for this loss of volume. Fortunately help is at hand! And it comes in the form of hyaluronic acid, a revolumising active ingredient that helps our skin to harness moisture. Whether in a pot or a jab, hyaluronic acid revolumises and firms up skin, notably under the eyes, on our cheeks and around our mouths.
