In the Ultimate Serum it forms the hydrating base that the Vitamin C and plant-based collagen work within. Applied to clean skin before your moisturiser, it draws moisture to the surface and holds it there, making fine lines look shallower and skin feel noticeably fuller within the first few uses. It is one of the few skincare ingredients where the effect is visible quickly rather than requiring weeks of buildup." } }, { "@type": "Question", "name": "Is the Ultimate Serum suitable for oily skin?", "acceptedAnswer": { "@type": "Answer", "text": "Yes, and Hyaluronic Acid is a significant reason why. It provides hydration through water binding rather than oil, so it gives oily skin what it actually needs without contributing to shine or congestion. Oily skin is often also dehydrated, which is counterintuitive but common. The skin overproduces oil partly in response to dehydration. Using the Ultimate Serum adds the hydration that reduces that compensatory oil production over time, which means skin can actually become less oily with consistent use rather than more." } }, { "@type": "Question", "name": "Should I use the Ultimate Serum before or after my moisturiser?", "acceptedAnswer": { "@type": "Answer", "text": "Before. Always apply serums before moisturisers. The serum contains smaller molecules, including Hyaluronic Acid, that need direct contact with the skin to penetrate effectively. Applying moisturiser first creates a barrier that blocks that absorption. The correct order is cleanse, then Ultimate Serum on slightly damp skin, allow two minutes to absorb, then apply the Daily Moisturiser over the top to seal everything in. The moisturiser layer helps the Hyaluronic Acid retain the moisture it has drawn in rather than letting it evaporate." } }, { "@type": "Question", "name": "Which Aussie Man products contain Hyaluronic Acid?", "acceptedAnswer": { "@type": "Answer", "text": "Hyaluronic Acid is found in the Ultimate Serum, where it is the primary hydrating active alongside plant-based Vegetable Collagen from seaweed and L-Ascorbic Acid Vitamin C. It is a targeted, high-performance ingredient in a serum format rather than something spread thinly across multiple products. If hydration and fine line reduction are your main concerns, the Ultimate Serum is the product to focus on, used before the Daily Moisturiser in both your morning and evening routine." } }, { "@type": "Question", "name": "Why does the Ultimate Serum use plant-based collagen alongside Hyaluronic Acid?", "acceptedAnswer": { "@type": "Answer", "text": "Hyaluronic Acid handles the hydration. The plant-based Vegetable Collagen from seaweed handles the structural support. They address two different aspects of skin ageing simultaneously. Collagen in a topical formula does not directly replace the collagen in your skin, the molecules are too large to penetrate at that level. What it does is form a flexible film on the skin surface that supports elasticity and reduces the appearance of fine lines while the Hyaluronic Acid works on hydration depth. Together they address both the surface texture and the underlying plumpness that makes skin look younger." } } ] } ] --- [![The Aussie Man logo](https://theaussieman.com/cdn/shop/files/TAM_ASC_logo_20_93e60a6d-d573-4b14-ad22-44f52fba9983.png?v=1684379191&width=600)](/) [Home](/) Shop by Concern Guides [Products](/products)[Bundles](/bundles)[Ingredients](/ingredients)[Routines](/routines)[FAQs](/faqs)[Trust & Proof](/trust)[About](/about) [Visit Store](https://www.theaussieman.com) # Hyaluronic Acid Humectant Also known as: Sodium Hyaluronate, HA Last updated: April 2026 ## What is Hyaluronic Acid? Hyaluronic Acid is one of the few skincare ingredients that does exactly what the label says. It is a naturally occurring molecule found in the human body, concentrated in the skin, eyes, and connective tissue, where its primary job is to hold water and keep tissue lubricated and plump. The reason it works so well in skincare is straightforward: a single molecule of Hyaluronic Acid can bind up to 1,000 times its own weight in water. When applied topically, it draws moisture from the environment and from the deeper layers of the skin and holds it at the surface where it is most visible and most needed. In The Aussie Man range, Hyaluronic Acid is found in the Ultimate Serum, where it works alongside plant-based Vegetable Collagen from seaweed and L-Ascorbic Acid (Vitamin C). The serum is designed to be applied first in your morning or evening routine, before the moisturiser, so the Hyaluronic Acid can do its hydrating work on clean skin and the layers that follow seal it in. ## Key Benefits Hyaluronic acid is a humectant your skin already produces, but levels drop from the late twenties onwards. Applied topically it binds water to the surface of the skin, which plumps the look of fine lines, smooths texture and restores a hydrated appearance without leaving an oily finish. For men, hyaluronic acid is the fastest way to add moisture to dehydrated or post-shave skin without adding grease. It sits cleanly under a beard, absorbs quickly and layers well with other products. It suits oily, combination and sensitive skin as readily as dry skin, because it adds hydration rather than oil. The Aussie Man uses hyaluronic acid in the hydrating serum and daily moisturiser, where it draws moisture into the skin and helps lock it in through the day. ## Scientific Evidence Hyaluronic Acid is one of the most extensively studied ingredients in dermatology with a research base spanning several decades. A clinical study published in the Journal of Clinical and Aesthetic Dermatology demonstrated statistically significant improvements in skin hydration, elasticity, and the appearance of periorbital wrinkles in subjects using a topical Hyaluronic Acid formulation twice daily for eight weeks, compared to a vehicle control. Research published in Dermato-Endocrinology examined the role of endogenous Hyaluronic Acid in skin ageing, confirming that skin HA content declines measurably from the fourth decade onwards and that this decline is directly correlated with the loss of skin volume and the deepening of surface lines. The study supported topical supplementation as a practical strategy for partially compensating this age-related reduction. A review in the International Journal of Biological Macromolecules summarised the evidence for different molecular weight forms of Hyaluronic Acid in topical application, confirming that lower molecular weight forms penetrate more deeply into the epidermis while higher molecular weight forms remain at the surface to provide immediate hydration and barrier support, with the most effective formulas combining both. ## Frequently Asked Questions ### What does Hyaluronic Acid actually do in the Ultimate Serum? ### Is the Ultimate Serum suitable for oily skin? ### Should I use the Ultimate Serum before or after my moisturiser? ### Which Aussie Man products contain Hyaluronic Acid? ### Why does the Ultimate Serum use plant-based collagen alongside Hyaluronic Acid? ## Ingredient Category Hyaluronic Acid is classified as a humectant ingredient in skincare formulation.
