Shop Hydrating and Hyaluronic Acid Serums

While your day and night moisturisers will help to ensure consistent hydration, adding a hydrating serum into your beauty skin care routine is the best way to provide an intense moisture surge for healthier skin. Serums contain high concentrations of active ingredients and can be applied as all-over treatments or used to target specific areas of concern. Dehydrated skin can accentuate fine lines, wrinkles, dark circles, and pigmentation so by keeping your skin hydrated with a high potency serum, you can enjoy a clearer and smoother complexion.


Hyaluronic acid is one of the best natural skin care ingredients for hydration, boasting an outstanding ability to retain water within the skin while boosting collagen levels. As you age, your skin becomes unable to maintain hydration which causes loss of firmness and elasticity, leading to fine lines and wrinkles. Collagen production in the skin also slows down which speeds up signs of premature aging. Hyaluronic acid not only delivers an instant burst of moisture but will help lock in existing hydration from day to night and support collagen production for younger-looking skin.


Due to its lightweight texture, hyaluronic acid is perfect for all skin types from the driest of skin to oilier complexions. Perfect for sensitive and blemish-prone skin, hyaluronic acid is also incredibly gentle and soothing to reactive skin types and will help retain moisture during a sensitivity flare-up.


Including a hydrating serum in both your morning and evening skin care routine is the best way to boost hydration and lock in moisture for healthy skin all day long. Our selection of Hydrating and Hyaluronic Acid Serums includes the bestselling The Ordinary Hyaluronic Acid 2% + B5 and The Ordinary Lactic Acid 10% + HA which works to exfoliate skin without causing dryness.

Just.. okay?

I used this hoping it would be similar to the DE B-Hydra (because it's a much more affordable price point!), but it didn't live up to expectations. It's in between a gel and serum consistency, and I found that it didn't really soak in and hydrate my skin. It seemed to sit on the surface a little bit. It was okay, but I wanted more moisture. If you have more oily than dry skin and you don't need as...

This product was recommended to me by an ex- beauty store employee when she encouraged me to switch from physical to chemical exfoliants. I LOVE THIS STUFF. It significantly reduced the clogging that occurred in my pores and has reduced the amount of whiteheads that sporadically pop up on my face.

I love this stuffffff. I have such dry skin and I love how the hyaluronic acid gives a deep hydration and plumpness to the skin. I use this with a facial mist as it is recommended to apply this onto a damp face and I find that it will soak right in. I use it as the first step in my routine both morning and nights and it gives me such great radiance and glow. LOVE IT
