Clinically proven to deliver over 90% increase in sustained hydration over 28 days, 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.

20% glycerin: Relieves dryness, and can act as an emollient to soften skin.

How to use
Step 2 of your skincare routine – treat

Can be used daily, AM and PM

Massage 2-3 drops into cleansed skin. Follow with our Hyaluronic Fix Extreme4 Hydrating Serum for maximum hydration.

Concentrates are lightweight and usually contain a high concentration of active products. They are best applied straight onto cleansed skin and can be followed with a serum or used alone


Using acids (such as pads or toner) as the active step in your routine? We recommend applying our Concentrate after your acid treatment and before your moisturiser. This will help soothe your skin, reducing the chance of irritation and enhancing the results of your active steps.

Glass skin foundation hack:

Step 1: Combine one drop of the Hyaluronic Fix Extreme4 Concentrate with 2-3 pumps of foundation, mix thoroughly on the back of your hand or on a palette.

Step 2: Apply with fingers or a brush, finish with a damp beauty sponge for the ultimate long lasting, glass-skin base.

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.

Boost your makeup
