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.

Quick and easy hydration!

I originally bought this for my partner's (combo/dry) skin, but have used it on my (oily) complexion quite a few times now. It's a lovely, watery consistency that soaks right in. I'm not sure how much of a difference it's made on my skin, but his skin is so much less dry!

This product is even more watery than water (NIOD seems to like this kind of formulation) which makes it really hard to apply and I feel like most of it's absorbed by my fingertips. I like that it's not sticky like the Ordinary hyaluronic acid is, but I do feel you'd be able to find a much more effective and user friendly version elsewhere for cheaper. Didn't notice any long term benefits from using this product as opposed to any other cheap version I've used.

Good for dry skin

Great for my dry skin. Super hydrating similar to that of my skincare company B3 which is $125 for the same size bottle. Great dupe.

Love it!

I highly recommend this product. My skin feels hydrated and firmer with each use. I wanted to try a product a step up from HA by the Ordinary and was recommened this product. I will be purchasing this product again. Loving the soft feel of my skin and goes well under makeup.
