The moisture barrier is the visible, top layer of skin you can touch, feel, and see. It’s called stratum corneum and it’s composed of layered, keratin-filled cells (corneocytes) that form a protective barrier and maintains skin hydration. The stratum corneum allows certain compounds to enter the skin and is responsible for making sure the body is not dehydrated. The keratin within corneocytes absorbs moisture, then loses that moisture as dead skin cells are replaced with new.

The moisture barrier protects the skin from external stressors. Loss of moisture causes it to shrink and crack, exposing the cells beneath resulting in irritation. Keeping the moisture barrier hydrated helps the body from premature ageing. It also protects deeper layers of the skin connected with blood vessels, nerves, and networks that continually regulate the body.

Skin with a healthy barrier is soft to the touch and looks smooth. If your skin looks and feels rough or is dull, and flaky, your moisture barrier is compromised.

Loss of moisture in your skin leads it to shrink and crack, exposing the cells beneath. Moisture loss results from lifestyle and diet deficiencies such as: not drinking enough water, excessive alcohol or caffeine consumption, or lacking vitamins A and B. Excessive bathing and washing hands with harsh soaps can also dry out the skin. Environmental factors such as extended exposure to heaters, too much sun or wind, and dry climates also lead to skin moisture loss.le forget to apply lotion or don’t apply enough. Regularly applying lotion can make a big difference!

Hydration is key—inside and out. Corneocytes, the keratin-filled cells that make up the stratum corneum, absorb water to plump up the skin and provide flexibility. Over time, the stratum corneum naturally loses moisture, which is why it’s important to seal your skin’s existing water content with moisturisers that help the skin renew itself without dehydrating. Instead of sitting on top of your skin, Renew uses effective moisturisers, like plant-based glycerin, that absorb further into the layers of your skin while simultaneously drawing more moisture from the air into the skin. Renew adds another protective barrier to the top of your skin with USP-grade petrolatum—a highly refined ingredient that seals in moisture, slowing water loss and helping maintain the moisture barrier.
