In Deep: Hyaluronic Acid 101

Hyaluronic acid. If you’re a regular on the beauty scene, you’ve seen it. For the less beauty-savvy, we promise, it’s nowhere near as scary as it sounds. Arguably the secret ingredient to softer, plumper, smoother skin, is an absolute must in any skincare routine. But understanding how to use it and what type to use can be tricky. We’ve got you covered. From moisturisers to serums, we’ve rounded up the hottest hyaluronic acid products on the market. Plus, we’re breaking down all the info you need to know. 

What is hyaluronic acid? 

In a nutshell, hyaluronic acid (aka HA) is a transparent, sticky liquid that’s naturally produced by our bodies. Think of it as a magnet for moisture, helping your skin retain as much H2O as possible. The result is skin that feels plump, radiant and hydrated. How? This genius ingredient can hold on to water molecules, acting like a sponge and soaking up 1,000 times its weight in water. Pretty impressive.


Serums are a great way to penetrate the skin and tackle skin issues. Want to wake up with a hydrated glow? It doesn’t get much better than Estée Lauder’s Advanced Night Repair. For a great everyday serum, you can use morning or night, check out The Inkey List’s Hyaluronic Acid or 111 Skin’s Hyaluronic Acid Aqua Booster. If you’re ready to invest, you can’t go wrong with Dr. Barbara Sturm’s Hyaluronic Serum. 

Why should you start using hyaluronic acid?  

We all want hydrated, healthy-looking skin and hyaluronic acid is your ticket. If you suffer from dryness or dehydration, hyaluronic acid can help your skin to feel less tight, more moisturised. Plus, it can also help with flakiness and dry patches. As you get older, your body’s natural ability to produce HA decreases and so does the skin elasticity. So, if you’re looking to hold on to your youthful-looking complexion, hyaluronic acid is the one. Think - the more hydrated your skin is, the plumper it appears and the plumper your skin, the less obvious the signs of ageing are. Clever. 


Lock all that good stuff in with a hydrating moisturiser. For dry or dehydrated skin types, Tata Harper’s Reparative Moisturiser is a must. If your skin is acne-prone, Mario Badescu’s Hyaluronic Dew Cream is the perfect balance of oil-free and hydrating. On a fight against anti-ageing? This Works’ My Wrinkles Extreme Cream has a unique formula that helps to diminish the appearance of fine lines and wrinkles. Last but definitely not least, sun protection is a must. This is why every skincare routine needs Estée Lauder’s Daywear Multi-Protection Anti-Oxidant 24H-Moisture Crème SPF15. 

What to look out for when picking a hyaluronic acid?  

Size matters. The larger the hyaluronic acid molecule, the better it is for locking in moisture and smoothing the surface of the skin. The smaller the molecule, the deeper the acid can penetrate (beyond the first layer of the skin). We recommend keeping an eye out for products that contain both.  


Misting is the easiest way to get an extra hit of hydration. For a face mist that does it all, we’re obsessed with Omorovicza, Epara and Dr. Barbara Sturm. Looking for something to go the extra mile? Evolve Beauty’s Organic Beauty Daily Defence Moisture Mist helps to protect, firm and calm the skin whilst giving an extra shot of moisture.  

How to pick a hyaluronic acid?  

Oily, dry, ageing, sensitive or acne-prone, every skin type or skin issue can benefit from using hyaluronic acid. But what type of product is best for you? Luckily, hyaluronic acid comes in all forms. From exfoliators and cleansers to serums and face masks, it’s easy to incorporate hyaluronic acid into your routine. If you have oily/acne-prone skin, keep an eye out for ‘oil-free’ moisturisers or opt for a hyaluronic acid-based cleanser. If your skin is ultra-dry/dehydrated, look for a serum or moisturiser with smaller molecule’s, this will help to deeply hydrate the skin.

How do you use hyaluronic acid?  

How you apply your hyaluronic acid depends on the type of product you’re using. If you’re applying a serum, this should go on after cleansing and toning but before oils and moisturisers.  

Hyaluronic acid loves moisture. So, for best results spritz skin with a hydrating face mist before or apply the serum to slightly damp skin. Top tip? We like to finish off with face mist – the more moisture the better. 


When you have an extra 10 minutes, a face mask is a perfect way to squeeze in some ‘me time'. Don’t have time for a pampering session? No worries, Lancôme’s Hydra Zen Hydrating Overnight Jelly Face Mask can be worn while you sleep. The dream. If you’re constantly travelling, we recommend always having Sarah Chapman’s 3D Moisture Infusion or Dr. Jart’s Cryo Rubber with Moisturising Hyaluronic Acid in your beauty bag. Intensely hydrating and nourishing, both masks are ideal for getting a dose of hyaluronic acid into your skincare routine. For a weekly treatment, we turn to Tata Harper’s Hydrating Floral Mask. Like a glass of water for the skin, it’s infused with macromolecular sizes of hyaluronic acid that hydrate and recharge.
