Bring dehydrated skin back to life with an ultra-moisturising serum that instantly replenishes and conditions skin for the ultimate dewy glow.

Clinically proven to deliver a 150% increase in instant hydration upon application*, it instantly replenishes and conditions skin. We’ve used two different weights of hyaluronic acid to ensure all layers of the skin get that much-needed hydration hit.

Clinical trial results

Clinically proven to deliver over 150% increase in instant hydration upon application and over 50% increase after 24 hours, with twice daily use.*

How it works:

2% pure high and low molecular weight hyaluronic acid: Penetrates the skin at different depths for wider hydration throughout the skin.

Active level tremella: A naturally derived form of hyaluronic acid, also known as snow mushroom. It delivers an added moisture shot by delivering water to the skin, which tackles fine lines and wrinkles.

Active level polyglutamic acid: A powerful surface hydrator able to hold four times more water than hyaluronic acid, and locking it in, forming a protective seal across the skin to reduce ongoing water loss.

How to use
Step 2 of your skincare routine – treat

Can be used daily, AM and PM

Serums are usually gel-like in texture and contain a high concentration of active ingredients. They can be applied straight onto cleansed skin and used on their own or applied after a concentrate.

This serum pairs perfectly with all of our active concentrates; apply the Hyaluronic Fix Extreme4 Serum before using your concentrate as a way to prep the skin with hydration. This method reduces the chance of dryness or irritation from active ingredients such as glycolic acid, salicylic acid or retinol. Ideal for beginners, those with sensitive skin, or anyone who loves a glow!

Follow with our Hyaluronic Fix Extreme4 Hybrid Gel Cream to seal in hydration for enhanced results.

The Science

With a complex of three hardworking hydration ingredients, our Extreme4 range works by first hitting the skin with a moisture shot of tremella, a naturally occurring form of hyaluronic acid that deliver moisture directly into the top layers of skin. Hyaluronic acid, which holds 1,000 times its weight in water, then penetrates the skin at a deeper level, helping it retain water: our complex contains two molecular weights for multi-depth hydration. Combined with polyglutamic acid, which can hold 4 times more water than hyaluronic acid, our complex can reach even deeper into skin while also sealing in moisture by creating a 'film' over skin to prevent moisture loss
