Ceramide 1, 3 & 6 II
Ceramides 1, 3 and 6 II are essential lipids naturally found in the skin that act like the mortar between the bricks of your skin barrier. In skincare they are prized for helping to restore and strengthen the skin’s protective layer, locking in moisture and shielding against environmental stress. They are especially popular in UK moisturisers, serums and barrier-repair creams.
How it works in skincare
In cosmetics ceramides 1, 3 and 6 II are identical or bio-identical copies of the ceramides found in human skin. They integrate into the intercellular lipid matrix of the stratum corneum, improving barrier cohesion, reducing transepidermal water loss and helping the skin retain softness and suppleness. Formulators often combine the three for optimal barrier support in creams, lotions and targeted treatments.

Where it comes from
While naturally present in human skin, the ceramides used in UK skincare are typically produced by bio-fermentation of plant oils such as wheat, rice or corn, yielding high-purity, sustainable ingredients suitable for cosmetic use.
