Our skin barrier, also known as the moisture barrier, stratum corneum or acid mantle is made up of the uppermost layers of the skin, it’s watertight and protects the deeper layers of the epidermis from being damaged by irritants. A healthy skin barrier looks plump, hydrated, and smooth, but if the barrier becomes damaged it can feel rough, be red, dry, and uncomfortable. A compromised skin barrier can lead to more issues, as external aggressors like pollution particles make their way to the lower layers of skin, so it’s important to help repair any damage A consistent skincare routine is key, especially one that incorporates ingredients known to support barrier function.
For example, squalene can replenish moisture, retinol encourages healthy cell turnover, and salicylic acid gently exfoliates to unclog pores. It's also important to use lukewarm water when washing your skin, because both cold and hot water can aggravate the skin's natural lipid balance.

Glacial Glycoprotein
Glacial glycoprotein is a naturally occurring compound found deep inside Antarctic glaciers. To survive in such an extreme environment, glacial glycoprotein has to be tough, so it’s no wonder it is a great skin protector. When included in skincare it helps to defend the skin against the drying effects of cold air and can provide long-lasting hydration. Glacial glycoprotein also helps to protect the skin against water loss, leaving it looking smoother and feeling softer over time.
Here at Kiehl’s we synthesise glacial glycoprotein in labs so as not to disturb the delicate balance of the Arctic ecosystem.
