The Ordinary Hyaluronic Acid 2% + B5

£7.90 - £13.90

Retain your skin’s moisture with The Ordinary Hyaluronic Acid 2% + B5, a lightweight serum that hydrates every level of the dermis ideal for all skin types, especially dehydrated complexions.

The Ordinary Hyaluronic Acid 2% + B5 harnesses the power of vegan HA, which is known to reduce the visibility of fine lines and wrinkles, helping to retain a fresh, revitalised and youthful complexion. Unlike like most HA serums, the ordinary provides lasting hydration thanks to a combination of low, medium and high molecular weights of hyaluronic acid (HA); along with a next-generation HA crosspolymer, to provide multi-depth hydration that isn’t just a temporary fix on the surface of the skin.

The 2% Hyaluronic Acid Serum is also fortified with Vitamin B5, which helps the skin defend itself from external stresses and damaging free radicals linked to ageing. B5 works by moisturising underneath the skin’s barrier, soothing and protecting skin from irritation by reducing itching, redness and inflammation.

Why We Love It

Every skin type can be rehydrated by Hyaluronic Acid 2% + B5, as it enhances the skin’s ability to retain moisture, offering a more in-depth level of hydration by penetrating deeper due to the combined molecular weights of HA. The Ordinary’s clear serum instantly absorbs into the skin, and complexion looks and feels smoother straight away. You can easily apply just the right amount each time thanks to the built-in pipette.

How To Use It

Use the pipette to extract some of the formula, and apply onto your face and then massage into the skin.

Apply a few drops to the skin every morning and evening before applying your creams.

Rated 5 out of 5 by from Excellent Product Great serum, skin is so much better when using this. Dampen your face first before applying and the serum will last a lot longer and absorbs better too. Very reasonably priced, and have used for many years.

Rated 5 out of 5 by from Best serum of its kind I've tried other hyaluronic acid serums but this is the best, and one of the cheapest on the market. It's quite thick so only a couple of drops are needed and should be used over damp (not dry) skin for maximum effectiveness. I've been using it twice a day for about 4 months and have noticed a real improvement in hydration; skin feels less dry, looks brighter and plumper, and I have less need to use heavier creams as I usually do when cooler weather arrives. This serum is gentle, fragrance-free and absorbs easily. Now a staple in my skincare routine.

Rated 1 out of 5 by from First time I get sensitive skin from Hyaluronic I am not sure I will be able to use. My skin is painful, red and peeling. Not giving me a lux feel, shame because it has a good texture and it has a good price. Wont buy again.
