Before we jump the gun, and just tell you about our favourite hyaluronic acid serums, we thought it would be good idea to tell you about this magic active ingredient that everyone keeps raving about. As our skin ages, our skin’s natural production of hyaluronic acid decreases. Since hyaluronic acid has water retention properties, a lack of hyaluronic acid in our skin makes it dull, lifeless and less plump. Hence, including a hyaluronic acid serum makes the moisturiser absorb better and gives you glowing, plumper, younger looking skin in a matter of minutes. Now that you know how it works, read on to know our favourites.

Loved by most beauty editiors, this serum by Dr. Barbara Sturm's contains long- and short-chain hyaluronic molecules that intensely hydrate in addition to smoothing fine lines. In non-science-speak, having a variety of molecular sizes means that the ingredients can penetrate the deeper layers of your skin, while also providing instant results. While it does produce magical results, it also comes at a price. So pick this one up only if you really feel the need to splurge.

In the world of K-beauty, the word "ampoule" and "serum" are sometimes used interchangeably to describe a lightweight-yet-potent formula that goes on before your essence or moisturizer. The Plant Base Waterfall Moist Balanced Hyaluronic Acid 100 is made with 100 percent pure sodium hyaluronate, which penetrates deep into the skin to plump it with moisture.

If you're not quite ready to get volumizing fillers (no pressure), try incorporating a hyaluronic acid concentrate into your routine to get plumper, smoother-looking skin sans needles. We like the Kiehl's Powerful-Strength Line-Reducing Concentrate, which is also spiked with 12.5 percent vitamin C to brighten as it plumps.

Your skin can’t drink H20, but it can definitely drink up Drunk Elephant's B-Hydra Intensive Hydration Serum. Fortified with sodium hyaluronate (aka a water-soluble, salt form of hyaluronic acid), this serum delivers the intense moisturisation and antioxidant benefits mature skin craves.

Who doesn’t want skin that’s so happy that it bounces? This serum is your shortcut for the happy skin you thought only existed in your dreams. The serum instantly delivers dewier complexion, thanks to skin-plumping hyaluronic acid and vitamin B5.

All those k-drama, k-pop stars are giving you impossible ‘glass skin’ goals you can’t live upto? Not anymore! This skin refining serum takes inspiration from the glass skin trend to formulate a serum (packed with hyaluronic acid, peach extract, niacinamide, and peptides) to bestow you with skin that’s luminous, translucent and dewy!

Now that you know it comes from a drugstore brand, you already know it won’t be breaking any bank account. But the serum is all about giving you a non-sticky feel and plumping effect and a dewy, hydrated glow. Its over 1000 five star reviews are proof to that statement.

The Ordinary is known for their low-cost high effective line of skincare products. Hence, it is not surprising that it is almost always sold out. The weightless formula delivers deep hydration that keeps the skin's natural moisture levels at an all-time high, with an added boost of strengthening B5, all the while being a budget buy.

You know that first glorious glass of cold water in the morning after a long, thoroughly dehydrating night out? Yep, this is that in a facial serum. The sensitive skin-friendly formula has 89% mineralizing water that feels like your skin is taking a sip from the Fountain of Youth.
