What is Hyaluronic Acid?
Hyaluronic acid (HA) is a naturally occurring substance found within the skin. Classified as a glycosaminoglycan, it plays a crucial role in maintaining skin hydration and supporting connective tissue. HA’s impressive ability to hold up to 1,000 times its weight in water makes it a powerful humectant. This means it attracts and retains moisture in the skin, similar to a sponge.
Similar to collagen and elastin, our body’s natural production of HA declines with age. This contributes to dryness, fine lines, and a loss of skin plumpness. Topical application of HA in skincare can help address these concerns. By drawing and retaining moisture in the skin, HA helps slow down transepidermal water loss (TEWL), the process by which water evaporates from the skin’s surface. This translates to plumper, smoother skin with a more youthful appearance.
What can Hyaluronic Acid do for your skin?
Moisturising – often referred to as the “moisture magnet,” HA’s unique ability lies in attracting and retaining up to 1,000 times its weight in water. This surge in hydration plumps the skin, visibly reducing the appearance of fine lines and wrinkles, leaving your complexion looking smoother and more youthful.1
Anti-ageing – as we age, our body naturally produces less HA. This, combined with external stressors like UV exposure, contributes to visible signs of ageing like wrinkles and loss of elasticity. Studies suggest it may stimulate collagen production, a key protein that provides structural support to the skin. This can lead to plumper and firmer skin.2
Skin Barrier – with its remarkable ability to retain moisture, it helps keep the skin barrier functioning optimally. This, in turn, reduces the risk of dehydration, irritation, and other skin concerns.
Anti-inflammatory – boasting anti-inflammatory benefits, it can soothe irritated skin and reduce redness. Studies suggest it may play a role in supporting tissue repair functions. This makes HA a valuable ingredient for those with sensitive skin or concerns like eczema or rosacea.3
