Harnessing the world’s first Hydrolytic® Enzyme Technology proven to diversify the skin’s microbiome, a key driver of hydration, barrier control and clarity.
Your microbiome matters more than you think
Your skin isn’t just skin. It’s a living barrier made up of trillions of microbes that protect, hydrate, and renew your skin. This is your microbiome.
But stress, pollution, over-cleansing, antibiotics and age can dramatically reduce that diversity, compromising your skin's ability to regenerate and protect itself².
75% of people in Western countries have a deficient skin microbiome¹. This leads to dryness, dullness, sensitivity, and a weaker skin barrier.
Just like the gut, your skin needs a diverse microbiome to work at its best

Bi-phase action: the Hydrolytic® Enzyme
Backed by 30+ years of clinical research, our patented Hydrolytic® Enzyme technology works in two key synergistic ways to mimic and enhance your skin’s natural defences.
Phase One: Precision exfoliation
By mimicking the skin’s natural cell renewal process, it selectively removes harmful bacteria - creating more space for beneficial microbes to repopulate.
Phase Two: Microbiome renewal
At the same time, it creates optimal conditions for good bacteria to thrive, creating a healthy and balanced microbiome, reinforcing the skin’s natural barrier over time.
Clinically shown to improve microbiome diversity by 38% and reduce acne-causing bacteria by 28% in 28 days⁴.
Not on your skin. For your skin.
“By breaking down harmful bacterial clusters, the Hydrolytic® Enzyme supports the growth of beneficial microbes, helping to stop imbalance from spreading and keeping the skin healthy, resilient and youthful.”
– Dr. Mats Clarsund, PhD, Chief Scientific Officer

Let’s Demystify Skincare
What is the Hydrolytic® Enzyme, and how does it work?
The Hydrolytic® Enzyme promotes microbiome diversity by preventing bacterial dominance and provides targeted dead cell exfoliation, ideal for sensitive skin.
Is the Hydrolytic® Enzyme suitable for sensitive skin?
Yes, the Hydrolytic® Enzyme is designed to work selectively without causing irritation, making it suitable for all skin types.
What's the difference between Hyaluronic Acid and the Hydrolytic® Enzyme?
Hyaluronic acid increases moisture content in your skin, while the Hydrolytic® Enzyme helps with cell renewal, microbiome balance and barrier protection.
How does the Hydrolytic® Enzyme improve hydration?
The Hydrolytic® Enzyme helps to retain moisture by promoting a healthy skin barrier, leading to better hydration and skin elasticity.
What makes the Hydrolytic® Enzyme different from other exfoliants?
Unlike harsher exfoliants such as physical and chemical exfoliants, the Hydrolytic® Enzyme only targets dead cells, avoiding over-exfoliation and maintaining the skin’s natural balance.
Is there scientific research supporting these claims?
Yes, consumer studies and various tests validate the effectiveness of the Hydrolytic® Enzyme in promoting healthy skin.
Can I use fjör products with other active ingredients?
fjör products are designed to be compatible with other skincare ingredients, enhancing overall skin care routines without conflict.
