Why it's Cultured.

Our weightless, results-driven formula uses powerful, new-era FutureFerments™ to deliver an immediate plumping effect, while kick-starting the skin’s own ability to self-renew, rebalance and regenerate itself. The result? Long-term skin health and ageless radiance, thanks to a restored barrier function, diverse microbiome and revitalised skin function.

Delivers Deep Hydration

Dry skin often takes on an older appearance, displaying deeper lines and a rougher texture. We use ingredients backed by science to deliver a revolutionary twofold approach to hydration. Firstly, Fermented hyaluronic acid, a supercharged version of this humectant hero, delivers intense hydration by drawing moisture deep into the skin, restoring the plump, dewy appearance we all associate with a more youthful-looking complexion. This is partnered with a prebiotic super-hydrator, Inulin, which works by replenishing the water resevoir on the skin to fortify the skin barrier and microbiome.

Supports the Microbiome

Any skin issue you’re experiencing now – from irritation and redness to breakouts and eczema – are all likely to link back to an impaired barrier function and compromised microbiome. Our new-era formulas are powered by FutureFerments™, with the skin’s precious microbiome in mind. This regenerative, skin-quenching serum contains powerful fermented actives with prebiotic effect, that work to accelerate and improve skin renewal, skin barrier function and microbiome health.

Supports Skin Self-Regeneration and Renewal

Did you know that as we age our skin slows down, becoming drier, stretched and less resilient? But did you also know that your skin has the ability to accelerate its own self-renewal and regeneration, in effect to behave younger? Thanks to a complex of powerful FutureFerments™ our serum supports and optimises your skin’s natural regeneration and renewal, improving skin barrier function, skin health and leaving skin at its radiant, ageless best.

Streamlines your Skincare

The more science-backed actives a product contains, the less of it you need to put on your face to get results. Cultured’s sustainability ethos encourages less waste, allowing you to adopt a more streamline routine that’s better for your skin, and the planet.

How to use

Use morning and evening on cleansed skin. Apply one pump using upward sweeping motions. Don’t neglect your neck! TRY: Applying it to slightly damp skin. Hyaluronic acid is a humectant, meaning it draws water into the skin. This technique maximises overall hydration levels. Can be used by itself as a mosituriser or under a day cream. Perfect as a make-up primer.

Absolutely favourite product! Great absorption. Leaves the skin moistures and rejuvenated.

Youthful skin

I love to use this serum after the cleansing milk. It absorbs quickly and makes skin looking and feeling fresh and youthful

Lovely Serum

The consistency is thin but rich. The serum applies easily and evenly; additionally, it absorbs into the skin quickly and doesn't leave any residue and it is not sticky or greasy. Works well with or without makeup. It is effective for any day or night skincare routine as hydration is always necessary.
