Why this works when other things didn't

Barrier creams and soothing creams calm a flare that is already happening. Gut protocols and elimination diets work on the inside. None of them reach the imbalance on your skin itself: a disrupted skin microbiome, where harmful bacteria shelter in biofilms and keep the barrier under pressure. That is why the reactivity keeps coming back.

The Hydrolytic® Enzyme works there. It gently lifts dead cells and breaks up biofilm, so beneficial bacteria can recover. +38% microbiome diversity in 28 days, measured in vivo by third-party researchers and published in a peer-reviewed journal.

How to use

Apply 2-3 drops of the Hydrolytic® Serum
Massage into the skin
Repeat AM + PM

What to expect

What the first weeks look like. Barrier figures come from an in vivo clinical study, measured one hour after a single application. Microbiome figures come from an in vivo study over 28 days of daily use, run by third-party researchers and published in a peer-reviewed journal.

Acid exfoliants Acid exfoliants
Probiotic serums Probiotic serums
Works with the skin microbiome Your skin's bacteria set pH, produce antimicrobial peptides and train immune response. Probiotic serums add bacterial ingredients or ferments. Hydrolytic® clears what harms so your own bacteria can recover.
Partial
Strengthens the barrier from first use Barrier strength rose 25% one hour after a single application of the serum. Retinol and acids often weaken the barrier first, before skin adjusts.
Partial
Exfoliates gently Hydrolytic® lifts only the dead cells your skin has already prepared to shed. Acids dissolve the bonds between cells. Retinol speeds up turnover instead of exfoliating directly.
Partial
No purge or adjustment period Purging is the flaking and congestion that follows a sudden jump in cell turnover. Nothing is forced with Hydrolytic®, so there is nothing to push through.

Common questions

Common questions

I've tried everything. Why would this be different? +

Most of what you've tried works on the barrier or on the inside, so it calms the flare but not the reason it returns. fjör works on the microbial balance on your skin itself. If that mechanism is wrong for you, 28 days will show it, and your first order is covered by our 60-day money-back guarantee.

Is the Hydrolytic® Serum safe for sensitive skin? +

Yes, the serum is designed for sensitive skin. We've minimized the number of ingredients to reduce potential reactions. Please check the ingredient list on our packaging or website, and do a patch test on your inner bicep if you're concerned about sensitivity before applying it to your face.

What is the shelf life? +

All fjör products have a 3 year shelf life and last 1 year once opened. Look for the PAO (period after opening) symbol on the pack: an open jar with a number and an M, showing how many months the product stays good after first use. Beyond that, it may be less effective or unsafe to use.

Is it safe to use while I'm pregnant/nursing? +

Based on the toxicology evaluation of the fjör products and stated intended use for adults, there are no precautions required for pregnant / nursing / breastfeeding women who are using the product.

However, we always recommend checking with your doctor before using any new products while pregnant or nursing.
