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.

The Ordinary Hyaluronic Acid 2% + B5 is rated 4.5 out of 5 by 16.
Rated 2 out of 5 by from Rather drying serum Despite the very good reviewsI find this serum makes my skin feel taut and dry and sometimes it smarts. I am persevering, but may give up.

Rated 5 out of 5 by from Good value product I love most all Deciem products that I’ve tried, right up to the Niod brand. To be honest I usually use the Niod MMHC which is the premium version of this. But there is nothing wrong with this as a value product. Nice texture absorbs well and works well. It’s excellent value and an essential product for daily routine.
