You don’t need to spend a lot to find a good hydrating serum. Here, we round up the best formulas that won’t break the bank.


Whether you’re a skincare buff or a bit of a beauty novice, you’re likely to be aware of hyaluronic acid.

The ultra-hydrating ingredient has caused a buzz in the beauty world in the past five years, promising plumper, bouncier and more juicy-looking skin. But what is hyaluronic acid, and do you need to shell out a fortune for a decent one?

What is hyaluronic acid?

Despite the name, hyaluronic acid isn’t your typical skincare acid. It’s a naturally occurring compound in the skin. As we age, our levels of hyaluronic acid deplete, resulting in dullness, fine lines and thirsty skin.

When added to our skincare routines, the gentle ingredient is suitable for all skin types, as it’s designed to hydrate, soothe and calm skin. Fine lines are left plumped and softened, breakouts and scars heal faster and skin looks brighter, clearer and healthier. 

Hyaluronic acid is a humectant, which means it retains and preserves moisture levels. Unlike moisturisers, which act as a barrier against trans-epidermal moisture loss (locking in hydration so that it can’t escape), hyaluronic acid acts as a ‘moisture magnet’, drawing hydration deep into the skin’s dermis. In fact, one gram of hyaluronic acid can hold up to six litres of water, retaining 1,000 times its own weight, making it one of the most effective hydration boosters around.

Because of its ability to attract moisture, using hyaluronic acid before applying any other serums or moisturisers will bolster any hydrating properties your other skincare has.

Of course, there are many different types of hyaluronic acid serums at many different price points. But that doesn’t mean there aren’t some great, affordable options out there.

Here we’ve rounded up the best affordable hyaluronic acid serums that guarantee major hydration – all under £30.
