Start with The Essential Set: The Cleanser, The Serum and The Day Cream, a complete three-step routine that saves you money compared to buying the products separately. See the product page for the price in your currency. If you prefer to start with one product, The Serum is the treatment step in the routine.

The Serum is the treatment step: it is lightweight, absorbs quickly and combines postbiotics, humectants and biomimetic lipids. The Day Cream hydrates and provides all-day comfort, with niacinamide and stabilised vitamin C. Use them together: serum first, then cream.

All our formulas are also designed for sensitive skin and contain no added fragrance. If your skin is sensitive or dry, start with The Serum. You can check the full ingredient list on each product page, and we recommend a patch test if you have any known sensitivities.

Barriers was born from a simple idea: healthy skin is not achieved by fighting the skin, but by supporting its natural function.

Our formulas are powered by FF-Symbiotic™, a proprietary extract grown from broccoli microgreens, daikon radish microgreens, and lion's mane, cultivated in our vertical farm in Barcelona.

Combined with biomimetic ingredients, FF-Symbiotic™ helps create formulas designed to work with the skin, promoting microbiome balance, strengthening the skin barrier, and helping to maintain hydration.
