As we age, our skin tissue becomes dehydrated and the collagen and elastin fibres lose their structure, resulting in a loss of skin volume and the formation of the facial wrinkles and folds that are common characteristics of aged skin.11,17,42
HA helps reduce wrinkles and improves skin health
Hyaluronic acid provides continuous moisture to our skin by binding up to 1000 times its weight in water. It is the only biological substance that can retain this amount of water. One of the hallmarks of youthful skin is its moisture content that helps keep the skin looking smooth, plump and healthy. With age, the ability of our skin to produce HA decreases: our skin loses moisture, resulting in a loss of firmness and elasticity.11,13,17,19,42,43
Hyaluronic acid also plays a significant role in reducing oxidative damage to our skin caused from both internal and external factors, such as UV irradiation (also referred to as photoageing).19
The primary way in which HA helps improve the appearance of photoaged skin is by reducing water loss from the epidermis.
Skin ageing is also influenced by hormonal changes: decreased production of sex hormones like oestrogen can lead to collagen degradation, which results in dryness, loss of elasticity and wrinkling of our skin.43
Newer generation HA dermal fillers have been specifically developed to adapt the movements and dynamism of our faces. They offer an immediate volume-boosting effect and are designed to create or restore facial volumes and resculpt facial contours.29
Thanks to its ability to stimulate collagen production and its excellent capacity to retain water, hyaluronic acid also keeps our skin smooth, plumped up and well hydrated.22
