Works with the skin microbiome Your skin's bacteria set pH, produce antimicrobial peptides and train immune response. They are part of the barrier, not passengers on it. Hydrolytic® supports them rather than stripping them.
Partial
Strengthens the barrier from first use The barrier is the outer layer that holds water in and irritants out. Hydrolytic® works on the surface without dissolving the lipids that hold that layer together, so there is no phase where the barrier is compromised before it improves.
No irritation or purge period Purging is the flaking and congestion that follows a sudden jump in cell turnover. Hydrolytic® releases only cells the skin has already prepared to shed, so nothing is forced and there is no adjustment period to push through.
Partial
No increase in sun sensitivity Retinoids and AHAs can leave skin more vulnerable to UV, which is why they are usually kept to night use. Hydrolytic® does not increase photosensitivity, so it works morning and evening.

Common questions

Common questions

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.
