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.

Not for me

When using Napoleon Complex Skin Renewal Serum I noticed an improvement in the appearance of my skin and in application of makeup when used. However I did feel a tingling irritation at times that was uncomfortable; probably not so good for those with sensitive skin.

Super Hydrating

This serum is very hydrating but hasn’t left my skin oily. It smells great and I have seen an improvement in my skin. It also leaves my skin super soft.

Night time face oil

It spreads very well and only need one or two drops for whole face and neck. It gets absorbed very quickly and doesn’t feel too greasy. I am happy with the hydrating effect. I prefer using it only at night as my combination skin looks a bit too shiny when used in the morning. I’ve noticed when this oil is applied after Vitamin C Suspension 30% in Silicone, sometimes it accelerates the stinginess of Vitamin C cream (only for a few seconds).

Just love this serum!

I have combination skin but tends to get quite dry in winter months. Hence, extra hydration is a must. I received this product as a sample. Although, I have used this product before and have loved it, I just found it too expensive so I didn't repurchase. Now that I have used the sample, it has just reminded me how good this serum is. It provides the hydration I need, brightens and smooths my skin as well as providing that much needed plump. Need to purchase again.
