Hydration, Hydration, Hydration: Our Best Hyaluronic Acid Serums and Creams 

What’s the hype around Hyaluronic Acid? Well, if it’s super hydrated, plumped up and glowing skin that you’re after, then this is the ingredient you need to add to your regime. With the ability to hold 1000 times itself in water weight, this heroic ingredient targets fine lines and lacklustre skin with ease. Here are the best Hyaluronic Acid serums and creams your parched skin will love. 

First things first: what is Hyaluronic Acid?

Hyaluronic Acid is a skincare ingredient that’s been in the spotlight a lot recently, but what actually is it? A sugar that naturally occurs in the skin, we recycle around 15 grams of it every. Single. Day. As a humectant, it draws water to it and is welcomed by the skin to top up moisture levels. 

Why is this ingredient so important for the health of our skin?

As we age, our skin creates less Hyaluronic Acid leading to a loss of elasticity and moisture. Topping this up with a cleanser, serum or cream can help to keep the skin hydrated on the surface and at a deeper level. Hyaluronic Acid benefits skin at all (st)ages, improving texture and preventing dehydration without causing irritation. 

And what does Hyaluronic Acid DO?

There are two types of Hyaluronic Acid and they both do slightly different things. High molecular weight Hyaluronic Acid is great for smoothing the skin and helping your complexion look healthier and happier. Low molecular weight Hyaluronic Acid is better to apply topically for specific skincare concerns. 

How do we fit Hyaluronic Acid into our skincare routines?

This skin-saving ingredient can be incorporated into every routine as it works so well with other actives and ingredients. It can help chemical exfoliants like Glycolic Acid and Salicylic Acid from drying out the skin, and is a dream duo with antioxidants like Vitamin C. Whether you prefer a cleanser, serum, or moisturiser, Hyaluronic Acid can fit into your skincare routine at any (or every step). It’s a real glow-getter. 

Which products do we recommend?

Look out for products that pair Hyaluronic Acid with other ingredients like Ceramides and Peptides to drench your skin in moisture and protect your barrier. We’ve fallen hard for Hyaluronic Acid in ALL its forms; check out our list of tried and tested formulas to find the hydration boost to best suit you.
