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.

Does hydrate but is also quite sticky, doesn’t smell great (kind of like plastic) and doesn’t do much amazing for the price.

I've tried a lot of the ordinary products and haven't been disappointed,
However, this product stands out the most as being one of the best purchases I've ever made for my skin.
I use the cleanser in the shower and this Hyaluronic acid afterwards every morning.
There is always such a visible difference after I have, as well.

I have fairly oily skin with a few dry patches, and could never find a way to get rid of them until I used this! I have been only using this for a week but my skin feels super soft and smooth.
I apply it at night where it does look a little oily but it is all good the next morning!
Love this and would definitely repurchase - a little goes a long way
